Interface MethodTypeEntry
- All Superinterfaces:
LoadableConstantEntry, PoolEntry
Models a
where
CONSTANT_MethodType_info
structure, or a symbolic reference
to a method type, in the constant pool of a class
file.
The use of a MethodTypeEntry
is modeled by a MethodTypeDesc
.
Conversions are through ConstantPoolBuilder.methodTypeEntry(MethodTypeDesc)
and asSymbol()
.
A method type entry is composite:
MethodTypeEntry
(Utf8Entry descriptor
)
descriptor
is a method descriptor
string.- See Java Virtual Machine Specification:

Method Details
-
constantValue
Returns a symbolic descriptor of this constant.This is equivalent to
asSymbol()
.- Specified by:
constantValue
in interfaceLoadableConstantEntry
- Returns:
- a symbolic descriptor of this constant
- See Also:
-
descriptor
-
asSymbol
MethodTypeDesc asSymbol()Returns a symbolic descriptor for the method type.- API Note:
- If only symbol equivalence is desired,
matches
should be used. It requires reduced parsing and can improveclass
file reading performance. - Returns:
- a symbolic descriptor for the method type
-
matches
Returns whether this entry describes the given method type.- Parameters:
desc
- the method type descriptor- Returns:
- whether this entry describes the given method type
