/**
* The input and output stack map frames of a basic block.
*
* <p>Stack map frames are computed in two steps:
*
* <ul>
* <li>During the visit of each instruction in MethodWriter, the state of the frame at the end of
* the current basic block is updated by simulating the action of the instruction on the
* previous state of this so called "output frame".
* <li>After all instructions have been visited, a fix point algorithm is used in MethodWriter to
* compute the "input frame" of each basic block (i.e. the stack map frame at the beginning of
* the basic block). See {@link MethodWriter#computeAllFrames}.
* </ul>
*
* <p>Output stack map frames are computed relatively to the input frame of the basic block, which
* is not yet known when output frames are computed. It is therefore necessary to be able to
* represent abstract types such as "the type at position x in the input frame locals" or "the type
* at position x from the top of the input frame stack" or even "the type at position x in the input
* frame, with y more (or less) array dimensions". This explains the rather complicated type format
* used in this class, explained below.
*
* <p>The local variables and the operand stack of input and output frames contain values called
* "abstract types" hereafter. An abstract type is represented with 4 fields named DIM, KIND, FLAGS
* and VALUE, packed in a single int value for better performance and memory efficiency:
*
* <pre>
* =====================================
* |...DIM|KIND|.F|...............VALUE|
* =====================================
* </pre>
*
* <ul>
* <li>the DIM field, stored in the 6 most significant bits, is a signed number of array
* dimensions (from -32 to 31, included). It can be retrieved with {@link #DIM_MASK} and a
* right shift of {@link #DIM_SHIFT}.
* <li>the KIND field, stored in 4 bits, indicates the kind of VALUE used. These 4 bits can be
* retrieved with {@link #KIND_MASK} and, without any shift, must be equal to {@link
* #CONSTANT_KIND}, {@link #REFERENCE_KIND}, {@link #UNINITIALIZED_KIND}, {@link #LOCAL_KIND}
* or {@link #STACK_KIND}.
* <li>the FLAGS field, stored in 2 bits, contains up to 2 boolean flags. Currently only one flag
* is defined, namely {@link #TOP_IF_LONG_OR_DOUBLE_FLAG}.
* <li>the VALUE field, stored in the remaining 20 bits, contains either
* <ul>
* <li>one of the constants {@link #ITEM_TOP}, {@link #ITEM_ASM_BOOLEAN}, {@link
* #ITEM_ASM_BYTE}, {@link #ITEM_ASM_CHAR} or {@link #ITEM_ASM_SHORT}, {@link
* #ITEM_INTEGER}, {@link #ITEM_FLOAT}, {@link #ITEM_LONG}, {@link #ITEM_DOUBLE}, {@link
* #ITEM_NULL} or {@link #ITEM_UNINITIALIZED_THIS}, if KIND is equal to {@link
* #CONSTANT_KIND}.
* <li>the index of a {@link Symbol#TYPE_TAG} {@link Symbol} in the type table of a {@link
* SymbolTable}, if KIND is equal to {@link #REFERENCE_KIND}.
* <li>the index of an {@link Symbol#UNINITIALIZED_TYPE_TAG} {@link Symbol} in the type
* table of a SymbolTable, if KIND is equal to {@link #UNINITIALIZED_KIND}.
* <li>the index of a local variable in the input stack frame, if KIND is equal to {@link
* #LOCAL_KIND}.
* <li>a position relatively to the top of the stack of the input stack frame, if KIND is
* equal to {@link #STACK_KIND},
* </ul>
* </ul>
*
* <p>Output frames can contain abstract types of any kind and with a positive or negative array
* dimension (and even unassigned types, represented by 0 - which does not correspond to any valid
* abstract type value). Input frames can only contain CONSTANT_KIND, REFERENCE_KIND or
* UNINITIALIZED_KIND abstract types of positive or {@literal null} array dimension. In all cases
* the type table contains only internal type names (array type descriptors are forbidden - array
* dimensions must be represented through the DIM field).
*
* <p>The LONG and DOUBLE types are always represented by using two slots (LONG + TOP or DOUBLE +
* TOP), for local variables as well as in the operand stack. This is necessary to be able to
* simulate DUPx_y instructions, whose effect would be dependent on the concrete types represented
* by the abstract types in the stack (which are not always known).

* exception handler block. The visited types must describe the values of the local variables and
* of the operand stack elements <i>just before</i> <b>i</b> is executed.<br>
* <br>
* (*) this is mandatory only for classes whose version is greater than or equal to {@link

* <br>
* The frames of a method must be given either in expanded form, or in compressed form (all frames
* must use the same format, i.e. you must not mix expanded and compressed frames within a single
* method):
*
* <ul>
* <li>In expanded form, all frames must have the F_NEW type.
* <li>In compressed form, frames are basically "deltas" from the state of the previous frame:
* <ul>
* <li>{@link Opcodes#F_SAME} representing frame with exactly the same locals as the
* previous frame and with the empty stack.
* <li>{@link Opcodes#F_SAME1} representing frame with exactly the same locals as the
* previous frame and with single value on the stack ( <code>numStack</code> is 1 and
* <code>stack[0]</code> contains value for the type of the stack item).
* <li>{@link Opcodes#F_APPEND} representing frame with current locals are the same as the
* locals in the previous frame, except that additional locals are defined (<code>
* numLocal</code> is 1, 2 or 3 and <code>local</code> elements contains values
* representing added types).
* <li>{@link Opcodes#F_CHOP} representing frame with current locals are the same as the
* locals in the previous frame, except that the last 1-3 locals are absent and with
* the empty stack (<code>numLocal</code> is 1, 2 or 3).
* <li>{@link Opcodes#F_FULL} representing complete frame data.
* </ul>
* </ul>
*
* <br>
* In both cases the first frame, corresponding to the method's parameters and access flags, is
* implicit and must not be visited. Also, it is illegal to visit two or more frames for the same
* code location (i.e., at least one instruction must be visited between two calls to visitFrame).
*
* @param type the type of this stack map frame. Must be {@link Opcodes#F_NEW} for expanded
* frames, or {@link Opcodes#F_FULL}, {@link Opcodes#F_APPEND}, {@link Opcodes#F_CHOP}, {@link
* Opcodes#F_SAME} or {@link Opcodes#F_APPEND}, {@link Opcodes#F_SAME1} for compressed frames.
* @param numLocal the number of local variables in the visited frame. Long and double values
* count for one variable.
* @param local the local variable types in this frame. This array must not be modified. Primitive
* types are represented by {@link Opcodes#TOP}, {@link Opcodes#INTEGER}, {@link
* Opcodes#FLOAT}, {@link Opcodes#LONG}, {@link Opcodes#DOUBLE}, {@link Opcodes#NULL} or
* {@link Opcodes#UNINITIALIZED_THIS} (long and double are represented by a single element).
* Reference types are represented by String objects (representing internal names, see {@link
* Type#getInternalName()}), and uninitialized types by Label objects (this label designates
* the NEW instruction that created this uninitialized value).
* @param numStack the number of operand stack elements in the visited frame. Long and double
* values count for one stack element.
* @param stack the operand stack types in this frame. This array must not be modified. Its
* content has the same format as the "local" array.
* @throws IllegalStateException if a frame is visited just after another one, without any
* instruction between the two (unless this frame is a Opcodes#F_SAME frame, in which case it

* visitNewStuf(arg | (api < API_NEW ? SOURCE_DEPRECATED : 0), ...);
* }
*
* public void visitNewStuff(int argAndSource, ...) {
* if (api < API_NEW && (argAndSource & SOURCE_DEPRECATED) == 0) {
* visitOldStuff(argAndSource, ...);
* } else {
* int arg = argAndSource & ~SOURCE_MASK;
* [ do stuff ]
* }
* }
* }
* </pre>
*
* <p>If 'api' is equal to API_NEW, there are two cases:
*
* <ul>
* <li>call visitNewStuff: the redirection test is skipped and 'do stuff' is executed directly.
* <li>call visitOldSuff: the source is not set to SOURCE_DEPRECATED before calling
* visitNewStuff, but the redirection test is skipped anyway in visitNewStuff, which
* directly executes 'do stuff'.
* </ul>
*
* <p>If 'api' is equal to API_OLD, there are two cases:
*
* <ul>
* <li>call visitOldSuff: the source is set to SOURCE_DEPRECATED before calling visitNewStuff.
* Because of this visitNewStuff does not redirect back to visitOldStuff, and instead
* executes 'do stuff'.
* <li>call visitNewStuff: the call is redirected to visitOldStuff because the source is 0.
* visitOldStuff now sets the source to SOURCE_DEPRECATED and calls visitNewStuff back. This
* time visitNewStuff does not redirect the call, and instead executes 'do stuff'.
* </ul>
*
* <h1>User subclasses</h1>
*
* <p>If a user subclass overrides one of these methods, there are only two cases: either 'api' is
* API_OLD and visitOldStuff is overridden (and visitNewStuff is not), or 'api' is API_NEW or
* more, and visitNewStuff is overridden (and visitOldStuff is not). Any other case is a user
* programming error.
*
* <p>If 'api' is equal to API_NEW, the class hierarchy is equivalent to
*
* <pre>
* public class StuffVisitor {
* @Deprecated public void visitOldStuff(int arg, ...) { visitNewStuf(arg, ...); }
* public void visitNewStuff(int arg, ...) { [ do stuff ] }
* }
* class UserStuffVisitor extends StuffVisitor {
* @Override public void visitNewStuff(int arg, ...) {
* super.visitNewStuff(int arg, ...); // optional
* [ do user stuff ]
* }
* }
* </pre>
*
* <p>It is then obvious that whether visitNewStuff or visitOldStuff is called, 'do stuff' and 'do
* user stuff' will be executed, in this order.
*
* <p>If 'api' is equal to API_OLD, the class hierarchy is equivalent to
*
* <pre>
* public class StuffVisitor {
* @Deprecated public void visitOldStuff(int arg, ...) {
* visitNewStuff(arg | SOURCE_DEPRECATED, ...);
* }
* public void visitNewStuff(int argAndSource...) {
* if ((argAndSource & SOURCE_DEPRECATED) == 0) {
* visitOldStuff(argAndSource, ...);
* } else {
* int arg = argAndSource & ~SOURCE_MASK;
* [ do stuff ]
* }
* }
* }
* class UserStuffVisitor extends StuffVisitor {
* @Override public void visitOldStuff(int arg, ...) {
* super.visitOldStuff(int arg, ...); // optional
* [ do user stuff ]
* }
* }
* </pre>
*
* <p>and there are two cases:
*
* <ul>
* <li>call visitOldStuff: in the call to super.visitOldStuff, the source is set to
* SOURCE_DEPRECATED and visitNewStuff is called. Here 'do stuff' is run because the source
* was previously set to SOURCE_DEPRECATED, and execution eventually returns to
* UserStuffVisitor.visitOldStuff, where 'do user stuff' is run.
* <li>call visitNewStuff: the call is redirected to UserStuffVisitor.visitOldStuff because the
* source is 0. Execution continues as in the previous case, resulting in 'do stuff' and 'do
* user stuff' being executed, in this order.
* </ul>
*
* <h1>ASM subclasses</h1>
*
* <p>In ASM packages, subclasses of StuffVisitor can typically be sub classed again by the user,
* and can be used with API_OLD or API_NEW. Because of this, if such a subclass must override
* visitNewStuff, it must do so in the following way (and must not override visitOldStuff):
*
* <pre>
* public class AsmStuffVisitor extends StuffVisitor {
* @Override public void visitNewStuff(int argAndSource, ...) {
* if (api < API_NEW && (argAndSource & SOURCE_DEPRECATED) == 0) {
* super.visitNewStuff(argAndSource, ...);
* return;
* }
* super.visitNewStuff(argAndSource, ...); // optional
* int arg = argAndSource & ~SOURCE_MASK;
* [ do other stuff ]
* }
* }
* </pre>
*
* <p>If a user class extends this with 'api' equal to API_NEW, the class hierarchy is equivalent
* to
*
* <pre>
* public class StuffVisitor {
* @Deprecated public void visitOldStuff(int arg, ...) { visitNewStuf(arg, ...); }
* public void visitNewStuff(int arg, ...) { [ do stuff ] }
* }
* public class AsmStuffVisitor extends StuffVisitor {
* @Override public void visitNewStuff(int arg, ...) {
* super.visitNewStuff(arg, ...);
* [ do other stuff ]
* }
* }
* class UserStuffVisitor extends StuffVisitor {
* @Override public void visitNewStuff(int arg, ...) {
* super.visitNewStuff(int arg, ...);
* [ do user stuff ]
* }
* }
* </pre>
*
* <p>It is then obvious that whether visitNewStuff or visitOldStuff is called, 'do stuff', 'do
* other stuff' and 'do user stuff' will be executed, in this order. If, on the other hand, a user
* class extends AsmStuffVisitor with 'api' equal to API_OLD, the class hierarchy is equivalent to
*
* <pre>
* public class StuffVisitor {
* @Deprecated public void visitOldStuff(int arg, ...) {
* visitNewStuf(arg | SOURCE_DEPRECATED, ...);
* }
* public void visitNewStuff(int argAndSource, ...) {
* if ((argAndSource & SOURCE_DEPRECATED) == 0) {
* visitOldStuff(argAndSource, ...);
* } else {
* int arg = argAndSource & ~SOURCE_MASK;
* [ do stuff ]
* }
* }
* }
* public class AsmStuffVisitor extends StuffVisitor {
* @Override public void visitNewStuff(int argAndSource, ...) {
* if ((argAndSource & SOURCE_DEPRECATED) == 0) {
* super.visitNewStuff(argAndSource, ...);
* return;
* }
* super.visitNewStuff(argAndSource, ...); // optional
* int arg = argAndSource & ~SOURCE_MASK;
* [ do other stuff ]
* }
* }
* class UserStuffVisitor extends StuffVisitor {
* @Override public void visitOldStuff(int arg, ...) {
* super.visitOldStuff(arg, ...);
* [ do user stuff ]
* }
* }
* </pre>
*
* <p>and, here again, whether visitNewStuff or visitOldStuff is called, 'do stuff', 'do other
* stuff' and 'do user stuff' will be executed, in this order (exercise left to the reader).
*
* <h1>Notes</h1>
*
* <ul>
* <li>the SOURCE_DEPRECATED flag is set only if 'api' is API_OLD, just before calling
* visitNewStuff. By hypothesis, this method is not overridden by the user. Therefore, user
* classes can never see this flag. Only ASM subclasses must take care of extracting the
* actual argument value by clearing the source flags.
* <li>because the SOURCE_DEPRECATED flag is immediately cleared in the caller, the caller can
* call visitOldStuff or visitNewStuff (in 'do stuff' and 'do user stuff') on a delegate
* visitor without any risks (breaking the redirection logic, "leaking" the flag, etc).
* <li>all the scenarios discussed above are unit tested in MethodVisitorTest.
* </ul>

* Generates classes to handle multi-valued keys, for use in things such as Maps and Sets.

* <p>
* To generate a <code>KeyFactory</code>, you need to supply an interface which
* describes the structure of the key. The interface should have a
* single method named <code>newInstance</code>, which returns an
* <code>Object</code>. The arguments array can be
* <i>anything</i>--Objects, primitive values, or single or

* <p><pre>
* private interface IntStringKey {
* public Object newInstance(int i, String s);
* }
* </pre><p>
* Once you have made a <code>KeyFactory</code>, you generate a new key by calling
* the <code>newInstance</code> method defined by your interface.
* <p><pre>
* IntStringKey factory = (IntStringKey)KeyFactory.create(IntStringKey.class);
* Object key1 = factory.newInstance(4, "Hello");
* Object key2 = factory.newInstance(4, "World");
* </pre><p>
* <b>Note:</b>
* <code>hashCode</code> equality between two keys <code>key1</code> and <code>key2</code> is only guaranteed if
* <code>key1.equals(key2)</code> <i>and</i> the keys were produced by the same factory.

/**
* Generates dynamic subclasses to enable method interception. This
* class started as a substitute for the standard Dynamic Proxy support
* included with JDK 1.3, but one that allowed the proxies to extend a
* concrete base class, in addition to implementing interfaces. The dynamically
* generated subclasses override the non-final methods of the superclass and
* have hooks which callback to user-defined interceptor
* implementations.
* <p>
* The original and most general callback type is the {@link MethodInterceptor}, which
* in AOP terms enables "around advice"--that is, you can invoke custom code both before
* and after the invocation of the "super" method. In addition you can modify the
* arguments before calling the super method, or not call it at all.
* <p>
* Although <code>MethodInterceptor</code> is generic enough to meet any
* interception need, it is often overkill. For simplicity and performance, additional
* specialized callback types, such as {@link LazyLoader} are also available.
* Often a single callback will be used per enhanced class, but you can control
* which callback is used on a per-method basis with a {@link CallbackFilter}.
* <p>
* The most common uses of this class are embodied in the static helper methods. For
* advanced needs, such as customizing the <code>ClassLoader</code> to use, you should create
* a new instance of <code>Enhancer</code>. Other classes within CGLIB follow a similar pattern.
* <p>
* All enhanced objects implement the {@link Factory} interface, unless {@link #setUseFactory} is
* used to explicitly disable this feature. The <code>Factory</code> interface provides an API
* to change the callbacks of an existing object, as well as a faster and easier way to create
* new instances of the same type.
* <p>
* For an almost drop-in replacement for
* <code>java.lang.reflect.Proxy</code>, see the {@link Proxy} class.
