In visitMaxs, a fix point algorithm is used to compute the "input frame" of each basic - * block, i.e. the stack map frame at the begining of the basic block, starting from the input frame of the first - * basic block (which is computed from the method descriptor), and by using the previously computed output frames to - * compute the input state of the other blocks. All output and input frames are stored as arrays of integers. - * Reference and array types are represented by an index into a type table (which is not the same as the constant - * pool of the class, in order to avoid adding unnecessary constants in the pool - not all computed frames will end - * up being stored in the stack map table). This allows very fast type comparisons. 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 output frames. This format is the following: DIM KIND VALUE (4, 4 and 24 bits). DIM is a signed - * number of array dimensions (from -8 to 7). KIND is either BASE, LOCAL or STACK. BASE is used for types that are - * not relative to the input frame. LOCAL is used for types that are relative to the input local variable types. - * STACK is used for types that are relative to the input stack types. VALUE depends on KIND. For LOCAL types, it is - * an index in the input local variable types. For STACK types, it is a position relatively to the top of input - * frame stack. For BASE types, it is either one of the constants defined in FrameVisitor, or for OBJECT and - * UNINITIALIZED types, a tag and an index in the type table. Output frames can contain types of any kind and with a - * positive or negative dimension (and even unassigned types, represented by 0 - which does not correspond to any - * valid type value). Input frames can only contain BASE types of positive or null dimension. In all cases the type - * table contains only internal type names (array type descriptors are forbidden - dimensions must be represented - * through the DIM field). The LONG and DOUBLE types are always represented by using two slots (LONG + TOP or DOUBLE + - * TOP), for local variable types 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 actual type values if types were always represented by a - * single slot in the stack (and this is not possible, since actual type values are not always known - cf LOCAL and - * STACK type kinds). - */ - - /** - * Mask to get the dimension of a frame type.

- * 2. The class modifiers written as a 32-bit integer.
- * 3. The name of each interface sorted by name written using UTF encoding.
- * 4. For each field of the class sorted by field name (except private static
- * and private transient fields):
- * 1. The name of the field in UTF encoding.
- * 2. The modifiers of the field written as a 32-bit integer.
- * 3. The descriptor of the field in UTF encoding
- * 5. If a class initializer exists, write out the following:
- * 1. The name of the method, <clinit>, in UTF encoding.
- * 2. The modifier of the method, java.lang.reflect.Modifier.STATIC,
- * written as a 32-bit integer.
- * 3. The descriptor of the method, ()V, in UTF encoding.
- * 6. For each non-private constructor sorted by method name and signature:
- * 1. The name of the method, <init>, in UTF encoding.
- * 2. The modifiers of the method written as a 32-bit integer.
- * 3. The descriptor of the method in UTF encoding.

- * 1. The name of the method in UTF encoding.
- * 2. The modifiers of the method written as a 32-bit integer.
- * 3. The descriptor of the method in UTF encoding.
- * 8. The SHA-1 algorithm is executed on the stream of bytes produced by
- * DataOutputStream and produces five 32-bit values sha[0..4].
- * 9. The hash value is assembled from the first and second 32-bit values of 
- * the SHA-1 message digest. If the result of the message digest, the five
- * 32-bit words H0 H1 H2 H3 H4, is in an array of five int values named 
- * sha, the hash value would be computed as follows:
- * long hash = ((sha[0] >>> 24) & 0xFF) |
- * ((sha[0] >>> 16) & 0xFF) << 8 |
- * ((sha[0] >>> 8) & 0xFF) << 16 |

- * ((sha[1] >>> 24) & 0xFF) << 32 |
- * ((sha[1] >>> 16) & 0xFF) << 40 |
- * ((sha[1] >>> 8) & 0xFF) << 48 |
- * ((sha[1] >>> 0) & 0xFF) << 56;

-Provides an ASM visitor that constructs a tree representation of the -classes it visits. This class adapter can be useful to implement "complex" -class manipulation operations, i.e., operations that would be very hard to -implement without using a tree representation (such as optimizing the number -of local variables used by a method). -

- -

-However, this class adapter has a cost: it makes ASM bigger and slower. Indeed -it requires more than twenty new classes, and multiplies the time needed to -transform a class by almost two (it is almost two times faster to read, "modify" -and write a class with a ClassAdapter than with a ClassNode). This is why -this package is bundled in an optional asm-tree.jar library that -is separated from (but requires) the asm.jar library, which contains -the core ASM framework. This is also why it is recommended -not to use this class adapter when it is possible. -

- -

-The root class is the ClassNode, that can be created from existing bytecode. For example: -

- -
-  ClassReader cr = new ClassReader(source);
-  ClassNode cn = new ClassNode();
-  cr.accept(cn, true);
-
- -

-Now content of ClassNode can be modified and then -serialized back into bytecode: -

- -
-  ClassWriter cw = new ClassWriter(true);
-  cn.accept(cw);
-
- -

-Using simple ClassAdapter it is possible to create MethodNode instances per-method. -In this example MethodNode is acting as a buffer that is flushed out at visitEnd() call: -

- -
-  ClassReader cr = new ClassReader(source);
-  ClassWriter cw = new ClassWriter();
-  ClassAdapter ca = new ClassAdapter(cw) {
-      public MethodVisitor visitMethod(int access, String name, 
-          String desc, String signature, String[] exceptions) {
-        final MethodVisitor mv = super.visitMethod(access, name, desc, signature, exceptions);
-        MethodNode mn = new MethodNode(access, name, desc, signature, exceptions) {
-            public void visitEnd() {
-              // transform or analyze method code using tree API
-              accept(mv);
-            }
-          };
-      }
-    };
-  cr.accept(ca, true);
-
- -

-Several strategies can be used to construct method code from scratch. The first -option is to create a MethodNode, and then create XXXInsnNode instances and -add them to the instructions list: -

- -
-MethodNode m = new MethodNode(...);
-m.instructions.add(new VarInsnNode(ALOAD, 0));
-...
-
- -

-Alternatively, you can use the fact that MethodNode is a MethodVisitor, and use -that to create the XXXInsnNode and add them to the instructions list through -the standard MethodVisitor interface: -

- -
-MethodNode m = new MethodNode(...);
-m.visitVarInsn(ALOAD, 0);
-...
-
- -

-If you cannot generate all the instructions in sequential order, i.e. if you -need to save some pointer in the instruction list and then insert instructions -at that place after other instructions have been generated, you can use InsnList -methods insert() and insertBefore() to insert instructions at saved pointer. -

- -
-MethodNode m = new MethodNode(...);
-m.visitVarInsn(ALOAD, 0);
-AbstractInsnNode ptr = m.instructions.getLast();
-m.visitVarInsn(ALOAD, 1);
-// inserts an instruction between ALOAD 0 and ALOAD 1
-m.instructions.insert(ptr, new VarInsnNode(ALOAD, 0));
-...
-
- -

-If you need to insert instructions while iterating over an existing instruction -list, you can also use several strategies. The first one is to use a -ListIterator over the instruction list: -

- -
-ListIterator it = m.instructions.iterator();
-while (it.hasNext()) {
-    AbstractInsnNode n = (AbstractInsnNode) it.next();
-    if (...) {
-        it.add(new VarInsnNode(ALOAD, 0));
-    }
-}
-
- -

-It is also possible to convert instruction list into the array and iterate trough -array elements: -

- -
-AbstractInsnNode[] insns = m.instructions.toArray();
-for(int i = 0; i<insns.length; i++) {
-    AbstractInsnNode n = insns[i];
-    if (...) {
-        m.instructions.insert(n, new VarInsnNode(ALOAD, 0));
-    }
-}
-
- -

-If you want to insert these instructions through the MethodVisitor interface, -you can use another instance of MethodNode as a MethodVisitor and then -insert instructions collected by that instance into the instruction list. -For example: -

- -
-AbstractInsnNode[] insns = m.instructions.toArray();
-for(int i = 0; i<insns.length; i++) {
-    AbstractInsnNode n = insns[i];
-    if (...) {
