    • getSignature

      public String getSignature(ConstantPoolGen cpg)
      Returns:
      signature of referenced method/field.
    • getName

      public String getName(ConstantPoolGen cpg)
      Returns:
      name of referenced method/field.
    • getClassName

      public String getClassName(ConstantPoolGen cpg)
      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() method, which correctly distinguishes between class types and array types.
      Returns:
      name of the referenced class/interface
    • getClassType

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

      public ReferenceType getReferenceType(ConstantPoolGen cpg)
      Return 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)
    • getLoadClassType

      public ObjectType getLoadClassType(ConstantPoolGen cpg)
      Description copied from interface: LoadClass
      Returns the ObjectType of the referenced class or interface that may be loaded and resolved.
      Specified by:
      getLoadClassType in interface LoadClass
      Returns:
      type of the referenced class/interface
