Interface FieldInstruction
- All Superinterfaces:
- ClassFileElement,- CodeElement,- Instruction
Models a field access instruction in the 
code array of a Code
 attribute.  Corresponding opcodes have a kind
 of Opcode.Kind.FIELD_ACCESS.  Delivered as a CodeElement when
 traversing the elements of a CodeModel.
 A field access instruction is composite:
FieldInstruction(
    Opcode opcode,
    FieldRefEntry field,
)
