propagate

protected boolean propagate(T s_p,
 int i,
 T n,
 int j)

Description copied from class: TabulationSolver

Propagate the fact <s_p,i> -> <n, j> has arisen as a path edge. Returns <code>true</code> iff the path edge was not previously observed.

Overrides:

propagate in class TabulationSolver<T,P,F>

Parameters:

s_p - entry block

i - dataflow fact on entry

n - reached block

j - dataflow fact reached

getNumSteps

public int getNumSteps()

resetBound

public void resetBound()
