OpenJDK 27 · java.lang.classfile.constantpool.MethodTypeEntry

Models a CONSTANT_MethodType_info structure, or a symbolic reference to a method type, in the constant pool of a class file.

A method type entry is composite:

MethodTypeEntry(Utf8Entry descriptor)

where descriptor is a method descriptor string.

Method Summary

Modifier and Type	Method and Description
public MethodTypeDesc	Returns: a symbolic descriptor for the method type asSymbol() Returns a symbolic descriptor for the method type.
public default ConstantDesc	constantValue() Implements java.lang.classfile.constantpool.LoadableConstantEntry.constantValue. Returns a symbolic descriptor of this constant.
public Utf8Entry	Returns: the method descriptor string descriptor() Returns the method descriptor string.
public boolean	Returns: whether this entry describes the given method type matches(MethodTypeDesc the method type descriptor desc) Returns whether this entry describes the given method type.

asSymbol back to summary

asSymbol	back to summary
public 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 improve `class` file reading performance. Returns:MethodTypeDesc a symbolic descriptor for the method type

public 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 improve class file reading performance.

constantValue back to summary

constantValue	back to summary
public default ConstantDesc constantValue() Implements java.lang.classfile.constantpool.LoadableConstantEntry.constantValue. Doc from java.lang.classfile.constantpool.LoadableConstantEntry.constantValue. Returns a symbolic descriptor of this constant. This is equivalent to `asSymbol()`. Annotations @Override

public default ConstantDesc constantValue()

Returns a symbolic descriptor of this constant.

This is equivalent to asSymbol().
