getIterator

public abstract AlignFnc.AlignmentIterator getIterator(AntiUnifyProblem aup,
                                     int minAlignLen,
                                     int upperBound,
                                     boolean iterateAll,
                                     PrintStream out)
                                                throws MaximumIterationException

Initialize the computation. This method is called once before the iterations begin. For each pair, the user has to iterate over the alignment computation function AlignFnc and for each iteration the anti-unification algorithm should be called.

Throws:

MaximumIterationException - If the specified upper bound has been reached. Any value smaller than 1 disables the upper bound.

newInstance

public abstract AlignFnc newInstance()

Returns a fresh new instance of this alignment computation function.
