Modifier and Type	Method and Description
void	accept(InstructionVisitor insVisitor)
Instruction	execute(ThreadInfo ti) this is the real workhorse returns next instruction to enter in this thread <2do> it's unfortunate we roll every side effect into this method, because it diminishes the value of the 'executeInstruction' notification: all insns that require some sort of late binding (InvokeVirtual, GetField, ..) are not yet fully analyzable (e.g.
int	getByteCode()
int	getLength() return the length in bytes of this instruction.

Method Detail

popOperands1

protected void popOperands1(StackFrame frame)

Specified by:

popOperands1 in class FieldInstruction

popOperands2

protected void popOperands2(StackFrame frame)

Specified by:

popOperands2 in class FieldInstruction

execute

public Instruction execute(ThreadInfo ti)

Description copied from class: Instruction

this is the real workhorse returns next instruction to enter in this thread <2do> it's unfortunate we roll every side effect into this method, because it diminishes the value of the 'executeInstruction' notification: all insns that require some sort of late binding (InvokeVirtual, GetField, ..) are not yet fully analyzable (e.g. the callee of InvokeVirtuals is not known yet), putting the burden of duplicating the related code of enter() in the listener. It would be better if we factor this 'prepareExecution' out of enter()

Specified by:

execute in class Instruction

getLength

public int getLength()

Description copied from class: Instruction

return the length in bytes of this instruction. override if this is not 1

Overrides:

getLength in class Instruction

getByteCode

public int getByteCode()

Specified by:

getByteCode in class Instruction

isRead

public boolean isRead()

Specified by:

isRead in class FieldInstruction

accept

public void accept(InstructionVisitor insVisitor)

Specified by:

accept in interface InstructionVisitorAcceptor

Overrides:

accept in class StaticFieldInstruction
