Class FieldOrMethod

java.lang.Object
org.apache.bcel.generic.Instruction
org.apache.bcel.generic.CPInstruction
org.apache.bcel.generic.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)
      Constructs a FieldOrMethod.
      Parameters:
      opcode - the opcode.
      index - to constant pool.

  • Method Details

    • getClassName

      @Deprecated 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 (for example, 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.
      Gets the name of the referenced class/interface.
      Parameters:
      cpg - the constant pool generator.
      Returns:
      name of the referenced class/interface.

    • getClassType

      @Deprecated public ObjectType getClassType(ConstantPoolGen cpg)
      Deprecated.
      If the instruction references an array class, the ObjectType returned will be invalid. Use getReferenceType() instead.
      Gets the type of the referenced class/interface.
      Parameters:
      cpg - the constant pool generator.
      Returns:
      type of the referenced class/interface.

    • getLoadClassType

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

    • getName

      public String getName(ConstantPoolGen cpg)
      Gets the name of referenced method or field.
      Parameters:
      cpg - the constant pool generator.
      Returns:
      name of referenced method/field.

    • getReferenceType

      public ReferenceType getReferenceType(ConstantPoolGen cpg)
      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

      public String getSignature(ConstantPoolGen cpg)
      Gets the signature of referenced method or field.
      Parameters:
      cpg - the constant pool generator.
      Returns:
      signature of referenced method/field.
