Write

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

All Implemented Interfaces:

KnowledgeBaseConsumer, PredicateFactory
```
public final class Write
extends AbstractSingleResultPredicate
```
write(X) - writes a term to the output stream.
Writes the term X to the current output stream. write takes account of current operator declarations - thus an infix operator will be printed out between its arguments. write represents lists as a comma separated sequence of elements enclosed in square brackets.

Succeeds only once.

writeln(X) writes the term X to the current output stream, followed by a new line character. writeln(X) can be used as an alternative to write(X), nl.
