Method Detail

getName

public String getName()

Description copied from interface: iName

Returns the name of this instance.

Specified by:

getName in interface iName

Specified by:

getName in interface iTerm

Overrides:

getName in class jTerm

Returns:

String containing name of this instance.

prove

public boolean prove(jNameGoal ng)

convertStringToTerm

protected jTerm convertStringToTerm(String s,
                                    boolean pa)

convertListToString

protected String convertListToString(jList i)

convertStringToList

protected jList convertStringToList(String s)

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 jBinaryBuiltinPredicate

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 jBinaryBuiltinPredicate

Parameters:

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

goals - The iGoalStack to add the goal to.

duplicate

protected jBinaryBuiltinPredicate duplicate(jTerm lhs,
                                            jTerm rhs)

Specified by:

duplicate in class jBinaryBuiltinPredicate
