Constructor Detail

jTime

public jTime(jTerm c)
Method Detail

getName

public java.lang.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.

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.

duplicate

protected jUnaryBuiltinPredicate duplicate(jTerm t)
Specified by:
duplicate in class jUnaryBuiltinPredicate
