- * The input and output stack map frames of a basic block.
- *
- *
Stack map frames are computed in two steps:
- *
- *
- * 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".
- * 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}.
- *
- *
- * 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.
- *
- *
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:
- *
- *
- * =====================================
- * |.DIM|KIND|FLAG|...............VALUE|
- * =====================================
- *
- *
- *
- * the DIM field, stored in the 4 most significant bits, is a signed number of array
- * dimensions (from -8 to 7, included). It can be retrieved with {@link #DIM_MASK} and a right
- * shift of {@link #DIM_SHIFT}.
- * 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}.
- * the FLAGS field, stored in 4 bits, contains up to 4 boolean flags. Currently only one flag
- * is defined, namely {@link #TOP_IF_LONG_OR_DOUBLE_FLAG}.
- * the VALUE field, stored in the remaining 20 bits, contains either
- *
- * 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}.
- * 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}.
- * 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}.
- * the index of a local variable in the input stack frame, if KIND is equal to {@link
- * #LOCAL_KIND}.
- * a position relatively to the top of the stack of the input stack frame, if KIND is
- * equal to {@link #STACK_KIND},
- *
- *
- *
- * 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 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).
- *
- *
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).

- // the first basic block (known from the method signature), and by the using the previously

-/**
- * A {@link ClassVisitor} that adds a serial version unique identifier to a class if missing. Here
- * is typical usage of this class:
- *
- *
- * ClassWriter cw = new ClassWriter(...);
- * ClassVisitor sv = new SerialVersionUIDAdder(cw);
- * ClassVisitor ca = new MyClassAdapter(sv);
- * new ClassReader(orginalClass).accept(ca, false);
- *
- *
- * The SVUID algorithm can be found http://java.sun.com/j2se/1.4.2/docs/guide/serialization/spec/class.html :
- *
- *
- * The serialVersionUID is computed using the signature of a stream of bytes
- * that reflect the class definition. The National Institute of Standards and
- * Technology (NIST) Secure Hash Algorithm (SHA-1) is used to compute a
- * signature for the stream. The first two 32-bit quantities are used to form a
- * 64-bit hash. A java.lang.DataOutputStream is used to convert primitive data
- * types to a sequence of bytes. The values input to the stream are defined by
- * the Java Virtual Machine (VM) specification for classes.
- *
- * The sequence of items in the stream is as follows:
- *
- * 1. The class name written using UTF encoding.
- * 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.
- * 7. For each non-private method sorted by method name and signature:
- * 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[0] >>> 0) & 0xFF) << 24 |
- * ((sha[1] >>> 24) & 0xFF) << 32 |
- * ((sha[1] >>> 16) & 0xFF) << 40 |
- * ((sha[1] >>> 8) & 0xFF) << 48 |
- * ((sha[1] >>> 0) & 0xFF) << 56;
