Method Detail

visit

public boolean visit(int[][] result)

Get the current result of the combinatorics algorithm step.

Specified by:

Overrides:

visit in class org.matheclipse.combinatoric.AbstractListStepVisitor<IExpr>

Returns:

false if the combinatorics algorithm should stop immediately; true otherwise.
