FieldInstruction
protected FieldInstruction (short opcode,
int index)
Parameters: index
- to constant pool
toString
public java.lang.String toString (ConstantPool cp)
Overrides: toString
in class CPInstruction
Returns: mnemonic for instruction with symbolic references resolved
getFieldSize
protected int getFieldSize (ConstantPoolGen cpg)
Returns: size of field (1 or 2)
getType
public Type getType (ConstantPoolGen cpg)
Description copied from interface: LoadClass
Returns the type associated with this instruction.
LoadClass instances are always typed, but this type
does not always refer to the type of the class or interface
that it possibly forces to load. For example, GETFIELD would
return the type of the field and not the type of the class
where the field is defined.
If no class is forced to be loaded, null is returned.
An example for this is an ANEWARRAY instruction that creates
an int[][].
Specified by: getType
in interface TypedInstruction
Overrides: getType
in class CPInstruction
Returns: return type of referenced field
getFieldType
public Type getFieldType (ConstantPoolGen cpg)
Returns: type of field
getFieldName
public java.lang.String getFieldName (ConstantPoolGen cpg)
Returns: name of referenced field.
