Constructor Detail

SimpleGraph

public SimpleGraph(TripleCollection tripleCollection)

Creates a graph with the triples in tripleCollection

Parameters:

tripleCollection - the collection of triples this Graph shall consist of

SimpleGraph

public SimpleGraph(TripleCollection tripleCollection,
           boolean tripleCollectionWillNeverChange)

Creates a graph with the triples in tripleCollection. This construction allows to specify if the tripleCollection might change in future. If tripleCollectionWillNeverChange is set to true it will assume that the collection never changes, in this case the collection isn't copied making things more efficient.

Parameters:

tripleCollection - the collection of triples this Graph shall consist of

tripleCollectionWillNeverChange - true if the caller promises tripleCollection will never change

Method Detail

size

public int size()

Specified by:

size in interface Collection<Triple>

Specified by:

size in class AbstractCollection<Triple>

performFilter

public Iterator<Triple> performFilter(NonLiteral subject,
                             UriRef predicate,
                             Resource object)

Description copied from class: AbstractTripleCollection

A subclass of AbstractTripleCollection should override this method instead of filter for graph event support to be added. The Iterator returned by filter will dispatch a GraphEvent after invoking the remove method of the iterator returned by this method.

Specified by:

performFilter in class AbstractTripleCollection

Returns:
