Interface MethodHandleEntry
- All Superinterfaces:
LoadableConstantEntry,PoolEntry
Models a
where
CONSTANT_MethodHandle_info structure, or a symbolic
reference to a method handle, in the constant pool
of a class file. The method handle directly accesses an accessible
method, field, or constructor.
The use of a MethodHandleEntry is modeled by a DirectMethodHandleDesc. Conversions are through ConstantPoolBuilder.methodHandleEntry(DirectMethodHandleDesc) and asSymbol().
A method handle entry is composite:
MethodHandleEntry(
int refKind,
MemberRefEntry reference
)
refKind is in the range [1, 9].- See Java Virtual Machine Specification:
