Class FieldOrMethod

All Implemented Interfaces:
Cloneable, IndexedInstruction, LoadClass, TypedInstruction
Direct Known Subclasses:
FieldInstruction, InvokeInstruction

public abstract class FieldOrMethod extends CPInstruction implements LoadClass
Super class for InvokeInstruction and FieldInstruction, since they have some methods in common!
  • Constructor Details

    • FieldOrMethod

      protected FieldOrMethod(short opcode, int index)
      Parameters:
      index - to constant pool
  • Method Details

    • getClassName

      Deprecated.
      If the instruction references an array class, this method will return "java.lang.Object". For code generated by Java 1.5, this answer is sometimes wrong (e.g., if the "clone()" method is called on an array). A better idea is to use the getReferenceType(ConstantPoolGen) method, which correctly distinguishes between class types and array types.
      Returns:
      name of the referenced class/interface
    • getClassType

      Deprecated.
      If the instruction references an array class, the ObjectType returned will be invalid. Use getReferenceType() instead.
      Returns:
      type of the referenced class/interface
    • getLoadClassType

      Gets the ObjectType of the method return or field.
      Specified by:
      getLoadClassType in interface LoadClass
      Parameters:
      cpg - A ConstantPoolGen
      Returns:
      type of the referenced class/interface
      Throws:
      ClassGenException - when the field is (or method returns) an array,
    • getName

      Returns:
      name of referenced method/field.
    • getReferenceType

      Gets the reference type representing the class, interface, or array class referenced by the instruction.
      Parameters:
      cpg - the ConstantPoolGen used to create the instruction
      Returns:
      an ObjectType (if the referenced class type is a class or interface), or an ArrayType (if the referenced class type is an array class)
    • getSignature

      Returns:
      signature of referenced method/field.
