Method Detail

reduceHeap

protected void reduceHeap(JvmHeapAbstractState<ValueAbstractState> heap,
                          JvmFrameAbstractState<ValueAbstractState> frame,
                          MapAbstractState<java.lang.String,ValueAbstractState> staticFields)

Description copied from class: DefaultReduceOperator

Reduces the heap state. The default implementation doesn't perform any reduction.

Overrides:

reduceHeap in class DefaultReduceOperator<ValueAbstractState>

Parameters:

heap - the heap that is modified by this method by performing reduction

frame - the frame after reduction has been performed on it

staticFields - the static fields after reduction has been performed on them

createJvmAbstractState

                                                                      JvmFrameAbstractState<ValueAbstractState> frame,
