GETFIELD
GETFIELD()
- Empty constructor needed for the Class.newInstance() statement in
Instruction.readInstruction(). Not to be used otherwise.
GETFIELD
public GETFIELD(int index)
produceStack
public int produceStack(ConstantPoolGen cpg)
- Description copied from class:
Instruction
- This method also gives right results for instructions whose
effect on the stack depends on the constant pool entry they
reference.
- Specified by:
produceStack
in interface StackProducer
- Overrides:
produceStack
in class Instruction
- Returns:
- Number of words produced onto stack by this instruction,
or Constants.UNPREDICTABLE, if this can not be computed statically
getExceptions
public java.lang.Class[] getExceptions()
- Specified by:
getExceptions
in interface ExceptionThrower
accept
public void accept(Visitor v)
- Call corresponding visitor method(s). The order is:
Call visitor methods of implemented interfaces first, then
call methods according to the class hierarchy in descending order,
i.e., the most specific visitXXX() call comes last.
- Specified by:
accept
in class Instruction
- Parameters:
v
- Visitor object
