# 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` Structures
