Constructor Detail

FieldOrMethod

protected FieldOrMethod(short opcode, int index)

Parameters: index to constant pool

Method Detail

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

getLoadClassType

public ObjectType getLoadClassType(ConstantPoolGen cpg)

Returns: type of the referenced class/interface

getName

public String getName(ConstantPoolGen cpg)

Returns: name of referenced method/field.

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)

getSignature

public String getSignature(ConstantPoolGen cpg)

Returns: signature of referenced method/field.
