Interface FieldRefEntry

All Superinterfaces:: MemberRefEntry, PoolEntry

public sealed interface FieldRefEntry extends MemberRefEntry

Models a CONSTANT_Fieldref_info structure, or a symbolic reference to a field, in the constant pool of a class file.

A field reference constant pool entry is composite:

FieldRefEntry(
    ClassEntry owner,
    NameAndTypeEntry nameAndType
)

where the nameAndType.type() represents a field descriptor string.

See Java Virtual Machine Specification:

4.4.2 The CONSTANT_Fieldref_info,


            CONSTANT_Methodref_info

, and


            CONSTANT_InterfaceMethodref_info
