All Implemented Interfaces:

OSizeable, OAutoConvertToRecord, ODetachable, ORecordElement, ORecordLazyMultiValue, OTrackedMultiValue<OIdentifiable,OIdentifiable>, OIdentityChangeListener, Iterable<OIdentifiable>, Collection<OIdentifiable>, Set<OIdentifiable>

public class ORecordLazySet
extends ORecordTrackedSet
implements Set<OIdentifiable>, ORecordLazyMultiValue, ORecordElement, OIdentityChangeListener

Lazy implementation of Set. Can be bound to a source ORecord object to keep track of changes. This avoid to call the makeDirty() by hand when the set is changed.

Internals:

• stores new records in a separate IdentityHashMap to keep underlying list (delegate) always ordered and minimizing sort operations

Method Detail

detach

public boolean detach()

Description copied from interface: ODetachable

Detaches the object.

Specified by:

detach in interface ODetachable

Returns:

true if the object has been fully detached, otherwise false

iterator

public Iterator<OIdentifiable> iterator()

Specified by:

iterator in interface Iterable<OIdentifiable>

Specified by:

iterator in interface Collection<OIdentifiable>

Specified by:

iterator in interface Set<OIdentifiable>

Overrides:

iterator in class ORecordTrackedSet

rawIterator

public Iterator<OIdentifiable> rawIterator()

Specified by:

rawIterator in interface ORecordLazyMultiValue

add

public boolean add(OIdentifiable e)

Specified by:

add in interface Collection<OIdentifiable>

Specified by:

add in interface Set<OIdentifiable>

Overrides:

add in class ORecordTrackedSet

convertLinks2Records

public void convertLinks2Records()

Description copied from interface: ORecordLazyMultiValue

Description copied from interface: OIdentityChangeListener

Called before the change of the identity is made.

Specified by:

onBeforeIdentityChange in interface OIdentityChangeListener

convertRecords2Links

Browse all the set to convert all the items into links.

Specified by:

convertRecords2Links in interface ORecordLazyMultiValue

Returns:

clearDeletedRecords

remove

public boolean remove(Object o)

Specified by:

remove in interface Collection<OIdentifiable>

Specified by:

remove in interface Set<OIdentifiable>

Overrides:

remove in class ORecordTrackedSet
