Method Summary

Graph	getGraph() Returns the graph
boolean	performAdd(Triple e) A subclass of AbstractTripleCollection should override this method instead of add for graph event support to be added.
Iterator<Triple>	performFilter(NonLiteral subject, UriRef predicate, Resource object) A subclass of AbstractTripleCollection should override this method instead of filter for graph event support to be added.
void	setCheckConcurrency(boolean bool) Specifies whether or not to throw ConcurrentModificationExceptions, if this simple triple collection is modified concurrently.

public SimpleMGraph(Iterator<Triple> iterator)

Method Detail

getGraph

public Graph getGraph()

Description copied from interface: MGraph

Returns the graph

Specified by:

getGraph in interface MGraph

Returns:

graph

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:

performAdd

public boolean performAdd(Triple e)

Description copied from class: AbstractTripleCollection

A subclass of AbstractTripleCollection should override this method instead of add for graph event support to be added.

Overrides:

performAdd in class AbstractTripleCollection

Parameters:

e - The triple to be added to the triple collection

Returns:

setCheckConcurrency

public void setCheckConcurrency(boolean bool)

Specifies whether or not to throw ConcurrentModificationExceptions, if this simple triple collection is modified concurrently. Concurrency check is set to false by default.

Parameters:

bool - Specifies whether or not to check concurrent modifications.
