PoolEntrypublic sealed interface ModuleEntry extends PoolEntry
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)
name is a module name.CONSTANT_Module_info StructureTAG_CLASS, TAG_DOUBLE, TAG_DYNAMIC, TAG_FIELDREF, TAG_FLOAT, TAG_INTEGER, TAG_INTERFACE_METHODREF, TAG_INVOKE_DYNAMIC, TAG_LONG, TAG_METHOD_HANDLE, TAG_METHOD_TYPE, TAG_METHODREF, TAG_MODULE, TAG_NAME_AND_TYPE, TAG_PACKAGE, TAG_STRING, TAG_UTF8
