eObject

EObject eObject(Id id)

Returns the resolved EObject identified by the given id or null.

Parameters:

id - the identifier of the EObject to resolve

Returns:

the resolved EObject, or null if no EObject can be resolved

getAllInstances

default EList<EObject> getAllInstances(EClass eClass,
                                       boolean strict)

Back-end specific computation of Resource.getAllContents().

Parameters:

eClass - the EClass to compute the instances of

strict - true if the lookup searches for strict instances

Returns:

an EList containing all the EObjects that are instances of the given EClass

Throws:

UnsupportedOperationException - if the back-end does not support custom all instances computation

save

void save()
