jUnaryOperator

protected jUnaryOperator(jTerm r,
                         int t)

Method Detail

prove

public abstract boolean prove(jUnaryOperatorGoal og)

addGoals

public void addGoals(jGoal g,
                     jVariable[] vars,
                     iGoalStack goals)

Description copied from class: iPredicate

Adds goal to prove this predicate onto goal stack. This version is called when the original predicate must duplicate itself (or its arguments). Add goals in the reverse order you want them evaluated.

Overrides:

addGoals in class jUnaryBuiltinPredicate

Parameters:

g - The super-goal jGoal for the sub-goal that this function will add.

vars - The vector of duplicate variables produced from the previous call to registerVariables. Needed for call to duplicate.

goals - The iGoalStack to add the goal to.

addGoals

public void addGoals(jGoal g,
                     iGoalStack goals)

Description copied from class: iPredicate

Adds goal to prove this predicate onto goal stack. This version is called when the original predicate is already duplicated (usually as part of an argument for another predicate). Add goals in the reverse order you want them evaluated.

Overrides:

addGoals in class jUnaryBuiltinPredicate

Parameters:

g - The super-goal jGoal for the sub-goal that this function will add.

goals - The iGoalStack to add the goal to.

toString

public String toString(boolean usename)

Description copied from class: jTerm

Produces a string identifying this term, suitable for display to the console. param usename determines whether to display variables by name or identity. false is the default for displaying the term, true for displaying this term in a user query.

Specified by:

toString in interface iTerm

Overrides:

toString in class jUnaryBuiltinPredicate

Returns:

String which is a textual representation of this term.
