WriteCanonical

java.lang.Object
- org.projog.core.predicate.AbstractSingleResultPredicate
- - org.projog.core.predicate.builtin.io.WriteCanonical

All Implemented Interfaces:

KnowledgeBaseConsumer, PredicateFactory
```
public final class WriteCanonical
extends AbstractSingleResultPredicate
```
write_canonical(X) - writes a term to the output stream.
Writes the term X to the current output stream. write_canonical does not take account of current operator declarations - thus any structures are printed out with the functor first and the arguments in brackets.

Succeeds only once.
