InvokeInstruction
protected InvokeInstruction(short opcode,
                            int index)
- Parameters:
- index- to constant pool
toString
public java.lang.String toString(ConstantPool cp)
- 
- Overrides:
- toStringin class- CPInstruction
 
- 
- Returns:
- mnemonic for instruction with symbolic references resolved
 
consumeStack
public int consumeStack(ConstantPoolGen cpg)
- Also works for instructions whose stack effect depends on the
 constant pool entry they reference.
 
- 
- Specified by:
- consumeStackin interface- StackConsumer
- Overrides:
- consumeStackin class- Instruction
 
- 
- Returns:
- Number of words consumed from stack by this instruction
 
produceStack
public int produceStack(ConstantPoolGen cpg)
- Also works for instructions whose stack effect depends on the
 constant pool entry they reference.
 
- 
- Specified by:
- produceStackin interface- StackProducer
- Overrides:
- produceStackin class- Instruction
 
- 
- Returns:
- Number of words produced onto stack by this instruction
 
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:
- getTypein interface- TypedInstruction
- Overrides:
- getTypein class- CPInstruction
 
- 
- Returns:
- return type of referenced method.
- See Also:
- LoadClass.getLoadClassType(ConstantPoolGen)
 
getMethodName
public java.lang.String getMethodName(ConstantPoolGen cpg)
- 
 
- 
- Returns:
- name of referenced method.
 
getReturnType
public Type getReturnType(ConstantPoolGen cpg)
- 
 
- 
- Returns:
- return type of referenced method.
 
getArgumentTypes
public Type[] getArgumentTypes(ConstantPoolGen cpg)
- 
 
- 
- Returns:
- argument types of referenced method.
