All Implemented Interfaces:

OSizeable, OAutoConvertToRecord, ODetachable, ORecordElement, ORecordLazyMultiValue, OTrackedMultiValue<Object,OIdentifiable>, Serializable, Cloneable, Map<Object,OIdentifiable>

public class ORecordLazyMap
extends OTrackedMap<OIdentifiable>
implements ORecordLazyMultiValue

Lazy implementation of LinkedHashMap. It's bound to a source ORecord object to keep track of changes. This avoid to call the makeDirty() by hand when the map is changed.

isAutoConvertToRecord

public boolean isAutoConvertToRecord()

Specified by:

isAutoConvertToRecord in interface OAutoConvertToRecord

setAutoConvertToRecord

public void setAutoConvertToRecord(boolean convertToRecord)

Specified by:

setAutoConvertToRecord in interface OAutoConvertToRecord

convertLinks2Records

public void convertLinks2Records()

Description copied from interface: ORecordLazyMultiValue

Browse all the set to convert all the items into records. It converts only items that already loaded into memory from storage. To convert records that will be fetched from disk later use OAutoConvertToRecord.setAutoConvertToRecord(boolean)

Specified by:

convertLinks2Records in interface ORecordLazyMultiValue

convertRecords2Links

public boolean convertRecords2Links()

Description copied from interface: ORecordLazyMultiValue

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

Specified by:

convertRecords2Links in interface ORecordLazyMultiValue

Returns:

setDirty

public OTrackedMap<OIdentifiable> setDirty()

Description copied from interface: ORecordElement

Marks the instance as dirty. The dirty status could be propagated up if the implementation supports ownership concept.

Specified by:

setDirty in interface ORecordElement

Overrides:

setDirty in class OTrackedMap<OIdentifiable>

Returns:

The object it self. Useful to call methods in chain.

Specified by:

fireCollectionChangedEvent in interface OTrackedMultiValue<Object,OIdentifiable>

Overrides:

fireCollectionChangedEvent in class OTrackedMap<OIdentifiable>

getRecordType

Specified by:

rawIterator in interface ORecordLazyMultiValue

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

size

public int size()

Specified by:

size in interface OSizeable

Specified by:

size in interface Map<Object,OIdentifiable>

Overrides:

size in class HashMap<Object,OIdentifiable>
