Interface MethodTypeEntry

All Superinterfaces:

LoadableConstantEntry, PoolEntry

public sealed interface MethodTypeEntry
extends LoadableConstantEntry

Models a 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)

where descriptor is a method descriptor string.

Method Details

constantValue

default ConstantDesc constantValue()

Returns a symbolic descriptor of this constant.

This is equivalent to asSymbol().

Specified by:

constantValue in interface LoadableConstantEntry

Returns:

a symbolic descriptor of this constant

• ConstantPoolBuilder.loadableConstantEntry(ConstantDesc)

descriptor

Utf8Entry descriptor()

Returns the method descriptor string.

Returns:

the method descriptor string

asSymbol

MethodTypeDesc asSymbol()

Returns a symbolic descriptor for the method type.

Returns:

a symbolic descriptor for the method type

matches

boolean matches(MethodTypeDesc desc)

Returns whether this entry describes the given method type.

Parameters:

desc - the method type descriptor

Returns:

whether this entry describes the given method type
