Method Detail

fetchCompositeValue

void fetchCompositeValue(DeepaMehtaObjectModel parent)

Recursively fetches the composite value (child topic models) of the given parent object model and updates it in-place.

fetchChildTopics

void fetchChildTopics(DeepaMehtaObjectModel parent,
                      AssociationDefinition assocDef)

Recursively fetches the child topic models of the given parent object model and updates it in-place.

Works for both, "one" and "many" association definitions.

Parameters:

assocDef - The child topic models according to this association definition are fetched.

storeValue

void storeValue(DeepaMehtaObjectModel model,
                ClientState clientState,
                Directives directives)

Stores and indexes the specified model's value, either a simple value or a composite value (child topics). Depending on the model type's data type dispatches either to storeSimpleValue() or to storeCompositeValue().

Called to store the initial value of a newly created topic/association.

refreshLabel

void refreshLabel(DeepaMehtaObjectModel model)

Prerequisite: this is a composite object.

setSimpleValue

void setSimpleValue(DeepaMehtaObjectModel model,
                    SimpleValue value)

getType

Type getType(DeepaMehtaObjectModel model)

Convenience method to get the (attached) type of a DeepaMehta object model. The type is obtained from the core service's type cache.

storeSimpleValue
