FlatDiv

public FlatDiv(net.sourceforge.czt.z.ast.ZName a,

               net.sourceforge.czt.z.ast.ZName c)

Method Detail

chooseMode

public Mode chooseMode(Envir env)

Chooses the mode in which the predicate can be evaluated.

Specified by:

chooseMode in class FlatPred

Returns:

The Mode object, with statistics and an updated environment.

nextEvaluation

public boolean nextEvaluation()
                       throws EvalException

Does the actual evaluation

Specified by:

nextEvaluation in class FlatPred

Returns:

true iff another solution has been found.

Throws:

EvalException

toString

public String toString()

Description copied from class: FlatPred

A default implementation of toString. This returns "FlatXXX(args[0], args[1], ...)".

Overrides:

toString in class FlatPred

accept

public <R> R accept(net.sourceforge.czt.util.Visitor<R> visitor)

Description copied from class: FlatPred

Calls visitor.visitPred (preferably) or visitor.visitTerm. Subclasses that correspond to particular kinds of Pred should override this to call more specific visitXXX methods (and should call super to handle the remaining cases).

Overrides:
