InsertRecord

java.lang.Object
- org.projog.core.predicate.AbstractSingleResultPredicate
- - org.projog.core.predicate.builtin.db.InsertRecord

All Implemented Interfaces:

KnowledgeBaseConsumer, PredicateFactory
```
public final class InsertRecord
extends AbstractSingleResultPredicate
```
recorda(X,Y,Z) / recordz(X,Y,Z) - associates a term with a key.
recorda(X,Y,Z) associates Y with X. The unique reference for this association will be unified with Z. Y is added to the start of the list of terms already associated with X.

recordz(X,Y,Z) associates Y with X. The unique reference for this association will be unified with Z. Y is added to the end of the list of terms already associated with X.

    Description copied from class: AbstractSingleResultPredicate
    
    This method is called by AbstractSingleResultPredicate.setKnowledgeBase(KnowledgeBase).
    Can be overridden by subclasses to perform initialisation before any calls to AbstractSingleResultPredicate.evaluate(Term...) are made. As AbstractSingleResultPredicate.setKnowledgeBase(KnowledgeBase) will have already been called before this method is invoked, overridden versions will be able to access the KnowledgeBase using AbstractSingleResultPredicate.getKnowledgeBase().
    
    Overrides:
    
    init in class AbstractSingleResultPredicate

protected boolean evaluate(Term key,
                           Term value)
