Method Detail

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 interface InstructionInterface

Specified by:

getLength

public int getLength()

Description copied from class: Instruction

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

Specified by:

getLength in interface InstructionInterface

Overrides:

getLength in class Instruction

getByteCode

public int getByteCode()

accept

public void accept(JVMInstructionVisitor insVisitor)

toString

public java.lang.String toString()

Overrides:

toString in class Instruction
