MethodHandle constant 9 variations are stored using a range
of 9 values from ClassWriter.HANDLE_BASE
+ 1 to
ClassWriter.HANDLE_BASE
+ 9.
Special Item types are used for Items that are stored in the ClassWriter
ClassWriter.typeTable
, instead of the constant pool, in order to
avoid clashes with normal constant pool items in the ClassWriter constant
pool's hash table. These special item types are
ClassWriter.TYPE_NORMAL
, ClassWriter.TYPE_UNINIT
and
ClassWriter.TYPE_MERGED
.
