Method Detail

add

public boolean add(Triple e)

Specified by:

add in interface Collection<Triple>

Overrides:

add in class AbstractTripleCollection

addAll

public boolean addAll(Collection<? extends Triple> c)

Specified by:

addAll in interface Collection<Triple>

Overrides:

addAll in class AbstractCollection<Triple>

remove

public boolean remove(Object o)

Specified by:

remove in interface Collection<Triple>

Overrides:

remove in class AbstractTripleCollection

removeAll

public boolean removeAll(Collection<?> c)

Specified by:

removeAll in interface Collection<Triple>

Overrides:

removeAll in class AbstractTripleCollection

retainAll

public boolean retainAll(Collection<?> c)

Specified by:

retainAll in interface Collection<Triple>

Overrides:

retainAll in class AbstractCollection<Triple>

filter

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

Description copied from interface: TripleCollection

Filters triples given a pattern. filter(null, null, null) returns the same as iterator()

Specified by:

filter in interface TripleCollection

Overrides:

filter in class AbstractTripleCollection

Returns:

Iterator

delete

public void delete()

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.
