Package org.apache.jena.riot.lang

Class LangNTuple<X>

java.lang.Object

org.apache.jena.riot.lang.LangEngine

org.apache.jena.riot.lang.LangBase

org.apache.jena.riot.lang.LangNTuple<X>

All Implemented Interfaces:

Iterator<X>, LangRIOT

Direct Known Subclasses:

LangNQuads, LangNTriples

public abstract class LangNTuple<X>
extends LangBase
implements Iterator<X>

N-Quads, N-triples parser framework, with both push and pull interfaces.

• The LangBase.parse() method processes the whole stream of tokens, sending each to a Sink object.
• The Iterator<X> interface yields triples one-by-one.

Normally, bad terms causes the parser to stop (i.e. treat them as errors). In addition, the NTuples subsystem allows triples/quads with "bad" terms to be skipped. Checking can be switched off completely. If the data is known to be correct, no checking can be a large performance gain. Caveat emptor.
