Package org.apache.jena.riot.lang

Class LangNTuple<X>

  • All Implemented Interfaces:
    java.util.Iterator<X>, LangRIOT
    Direct Known Subclasses:
    LangNQuads, LangNTriples
    public abstract class LangNTuple<X>
extends LangBase
implements java.util.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.
