void |
accept(InstructionVisitor insVisitor) |
Instruction |
execute(ThreadInfo th)
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.

Instruction |
getTarget() |
boolean |
isBackJump()
answer if this is a potential loop closing jump
|
String |
toString() |
Instruction |
typeSafeClone(MethodInfo mi)
this is overridden by any Instruction that use a cache for class or
method to provide a type safe cloning
