Interface ESObjectContainer<T>

Type Parameters:

T - the ID type being used

All Known Subinterfaces:

ESLocalProject, IdEObjectCollection, NotifiableIdEObjectCollection, Project

All Known Implementing Classes:

ESLocalProjectImpl, IdEObjectCollectionImpl, NotifiableIdEObjectCollectionImpl, ProjectImpl

public interface ESObjectContainer<T>

A container for EObjects where each EObject has a unique ESModelElementId assigned to it.

The container does not specify how model elements are added or removed from the underlying collection of EObjects.

Method Detail

getModelElement

org.eclipse.emf.ecore.EObject getModelElement(T modelElementId)

Returns the model element with the given ESModelElementId.

Parameters:

modelElementId - the ID of the model element, that should be retrieved

Returns:

the model element that has the given ID assigned to it within the container

getModelElementId

T getModelElementId(org.eclipse.emf.ecore.EObject modelElement)

Retrieve the ESModelElementId of the given model element.

Parameters:

modelElement - the model element for which to retrieve the ID for

Returns:

the ESModelElementId of the given model element

getModelElements

org.eclipse.emf.common.util.EList<org.eclipse.emf.ecore.EObject> getModelElements()

Returns all directly contained model element of the container, i.e. a hierarchical representation of the model elements.

Returns:

a list containing the directly contained model elements within the container

getAllModelElements

Set<org.eclipse.emf.ecore.EObject> getAllModelElements()

Returns a flat representation of all model elements in the collection.

The returned set is not modifiable and will throw an UnsupportedOperationException in case trying to do so.

Returns:

a set of all model elements contained in the collection

contains

boolean contains(T modelElementId)

Checks whether the EObject with the given ESModelElementId is contained in the collection.

Parameters:

modelElementId - the model element ID of the EObject, which needs to be checked, whether it is contained in the collection

Returns:

true, if the EObject with the given model element ID is contained in the collection, false

contains

boolean contains(org.eclipse.emf.ecore.EObject modelElement)

Checks whether a given EObject is contained in the collection.

Parameters:

modelElement - the model element to be checked, whether it is contained in the collection

Returns:

true, if the model element is contained in the collection, false otherwise

getAllModelElementsByClass

<U extends org.eclipse.emf.ecore.EObject> Set<U> getAllModelElementsByClass(Class<U> modelElementClass,
                                                                            Boolean includeSubclasses)

Retrieve a list of all model elements of a certain type in the collection.

Type Parameters:

U - the type of the model element(s) to be retrieved

Parameters:

modelElementClass - the Class of the model element(s) to be retrieved

includeSubclasses - whether to also include all subclasses of the given Class in the list

Returns:

a list of model elements of the given type

getAllModelElementsByClass

<U extends org.eclipse.emf.ecore.EObject> Set<U> getAllModelElementsByClass(Class<U> modelElementClass)

Retrieve a list of all model elements of a certain type in the collection.

Type Parameters:

U - the type of the model element(s) to be retrieved

Parameters:

modelElementClass - the Class of the model element(s) to be retrieved

Returns:

a list of model elements of the given type
