Method Detail

clear

public void clear()

Specified by:

clear in interface Collection<Triple>

Overrides:

clear in class AbstractCollection<Triple>

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)

performFilter in class AbstractTripleCollection

Returns:

performAdd

public boolean performAdd(Triple triple)

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:

triple - The triple to be added to the triple collection

Returns:

performRemove

public boolean performRemove(Triple triple)

Description copied from class: AbstractTripleCollection

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

Overrides:

performRemove in class AbstractTripleCollection

Returns:
