java.lang.classfile.constantpool

public sealed Interface ModuleEntry

Known Direct Implementers: jdk.internal.classfile.impl.AbstractPoolEntry.ModuleEntryImpl
Imports: java.lang.constant.ModuleDesc, jdk.internal.classfile.impl.AbstractPoolEntry

Models a CONSTANT_Module_info structure, denoting a module, in the constant pool of a class file.

The use of a ModuleEntry is modeled by a ModuleDesc. Conversions are through ConstantPoolBuilder#moduleEntry(ModuleDesc) and asSymbol().

A module entry is composite:

ModuleEntry(Utf8Entry name)

where name is a module name.

Since: 24
Java Virtual Machine Specification: 4.4.11 The CONSTANT_Module_info Structure

asSymbol back to summary

asSymbol	back to summary
public ModuleDesc asSymbol() Returns a symbolic descriptor for the module name. API Note If only symbol equivalence is desired, `matches` should be used. It requires reduced parsing and can improve `class` file reading performance. Returns:ModuleDesc a symbolic descriptor for the module name

public ModuleDesc asSymbol()

Returns a symbolic descriptor for the module name.

API Note

If only symbol equivalence is desired, matches should be used. It requires reduced parsing and can improve class file reading performance.

matches	back to summary
public boolean matches(ModuleDesc desc) Returns whether this entry describes the given module. Parameters desc:ModuleDesc the module descriptor Returns:boolean whether this entry describes the given module Since 25
