+ * @author Eric Bruneton
+ */
+final class Frame {
+
+ /*
+ * Frames are computed in a two steps process: during the visit of each
+ * instruction, the state of the frame at the end of current basic block is
+ * updated by simulating the action of the instruction on the previous state
+ * of this so called "output frame". 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 beginning 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 below, 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).
