Method Detail

find

public ExtendedIterator<Triple> find(TriplePattern pattern)

Basic pattern lookup interface.

Specified by:

find in interface Finder

Parameters:

pattern - a TriplePattern to be matched against the data

Returns:

a ClosableIterator over all Triples in the data set that match the pattern

findWithContinuation

public ExtendedIterator<Triple> findWithContinuation(TriplePattern pattern,
                                                     Finder continuation)

Extended find interface used in situations where the implementator may or may not be able to answer the complete query. It will attempt to answer the pattern but if its answers are not known to be complete then it will also pass the request on to the nested Finder to append more results.

Specified by:

findWithContinuation in interface Finder

Parameters:

pattern - a TriplePattern to be matched against the data

continuation - either a Finder or a normal Graph which will be asked for additional match results if the implementor may not have completely satisfied the query.

getGraph

public Graph getGraph()

Returns the graph.

Returns:

Graph

contains

public boolean contains(TriplePattern pattern)

Return true if the given pattern occurs somewhere in the find sequence.

Specified by:

contains in interface Finder
