Interface MemberRefEntry

All Superinterfaces:

PoolEntry

All Known Subinterfaces:

FieldRefEntry, InterfaceMethodRefEntry, MethodRefEntry

public sealed interface MemberRefEntry
extends PoolEntry
permits FieldRefEntry, InterfaceMethodRefEntry, MethodRefEntry (not exhaustive)

Superinterface modeling symbolic references to a member of a class or interface in the constant pool of a class file, which include references to fields, class methods, and interface methods.

Different types of symbolic references to a member of a class or interface bear structural similarities and share parts of the resolution processes, and they can sometimes appear in the same locations. For example, both MethodRefEntry and InterfaceMethodRefEntry can appear in an invokestatic instruction.

A member reference entry is composite:

MemberRefEntry(
    ClassEntry owner,
    NameAndTypeEntry nameAndType
)

Modifier and Type	Method	Description
ConstantPool	constantPool()	Returns the constant pool this entry is from.

Method Details

owner

ClassEntry owner()

Returns the class or interface which this member belongs to.

Returns:

the class or interface which this member belongs to

nameAndType

NameAndTypeEntry nameAndType()

Returns the name and descriptor string of the member.

Returns:

the name and descriptor string of the member

name

default Utf8Entry name()

Returns the name of the member.

Returns:

the name of the member

type

default Utf8Entry type()

Returns the descriptor string of the member. This is a field descriptor string if this entry is a FieldRefEntry, or a method descriptor string if this entry is a MethodRefEntry or InterfaceMethodRefEntry.

API Note:

Each subinterface defines a typeSymbol() accessor for the symbolic descriptor for the member type.

Returns:

the descriptor string of the member
