Interface ModuleEntry

All Superinterfaces:

PoolEntry

public sealed interface ModuleEntry
extends PoolEntry

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.

See Java Virtual Machine Specification:

4.4.11 The CONSTANT_Module_info Structure

Method Summary

Modifier and Type	Method	Description
ModuleDesc	asSymbol()	Returns a symbolic descriptor for the module name.
boolean	matches(ModuleDesc desc)	Returns whether this entry describes the given module.
Utf8Entry	name()	Returns the name of the module.

Method Details

name

Utf8Entry name()

Returns the name of the module.

Returns:

the name of the module

asSymbol

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:

a symbolic descriptor for the module name

matches

boolean matches(ModuleDesc desc)

Returns whether this entry describes the given module.

Parameters:

desc - the module descriptor

Returns:

whether this entry describes the given module
