getId

long getId()

Specified by:

getId in interface Identifiable

getUri

String getUri()

setUri

void setUri(String uri)

getTypeUri

String getTypeUri()

setTypeUri

void setTypeUri(String typeUri)

getSimpleValue

SimpleValue getSimpleValue()

setSimpleValue

void setSimpleValue(String value)

setSimpleValue

void setSimpleValue(int value)

setSimpleValue

void setSimpleValue(long value)

getType

DeepaMehtaType getType()

Returns the type of this object.

No access control is performed as Implicit READ permission applies: if a user has READ access to an object she has READ access to its type as well.

Note: if the user would have no READ access to this object the DeepaMehta Core would not instantiate it in the first place, but throw an AccessControlException.

getModel

DeepaMehtaObjectModel getModel()

updateChildTopic

void updateChildTopic(RelatedTopicModel newChildTopic,
                      AssociationDefinition assocDef)

updateChildTopics

void updateChildTopics(List<? extends RelatedTopicModel> newChildTopics,
                       AssociationDefinition assocDef)

delete
