jJ2P
public jJ2P(jTerm lhs,
jTerm rhs)
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 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
public jBinaryBuiltinPredicate duplicate(jTerm t1,
jTerm t2)
- Specified by:
duplicate
in class jBinaryBuiltinPredicate
