Method Detail

version

public final java.lang.String version()

Description copied from interface: EntityState

Version of the entity. This is managed by the EntityStore.

If the underlying EntityStore does not support versioning, then version must always be set to 0.

Specified by:

version in interface EntityState

Returns:

version of the entity

lastModified

public long lastModified()

Description copied from interface: EntityState

Last modified timestamp of the entity. This is managed by the EntityStore.

If the underlying EntityStore does not support timestamping, then last modified must always be set to the current time.

Specified by:

lastModified in interface EntityState

Returns:

last modified timestamp of the entity, as defined by System.currentTimeMillis()

identity

public EntityReference identity()

Description copied from interface: EntityState

Returns the identity of the entity that this EntityState represents.

Specified by:

identity in interface EntityState

Returns:

the identity of the entity that this EntityState represents.

Specified by:

propertyValueOf in interface EntityState

setPropertyValue

public void setPropertyValue(QualifiedName stateName,
                             java.lang.Object newValue)

Specified by:
