Method Detail

addModelElement

void addModelElement(org.eclipse.emf.ecore.EObject modelElement)

Adds the given model element to the collection.

Parameters:

modelElement - the model element that should be added to the collection

clearAllocatedCaches

void clearAllocatedCaches()

Clear allocated caches.

clearAllocatedCaches

void clearAllocatedCaches(Set<ModelElementId> modelElementIds)

Clear caches from the given set of ModelElementIds.

Parameters:

modelElementIds - the collection of ModelElementIds to be removed from the allocated cache

allocateModelElementIds

void allocateModelElementIds(Map<org.eclipse.emf.ecore.EObject,ModelElementId> modelElementToIdMap)

Allocates certain IDs for the given model elements in the mapping. If any EObject contained in the mapping is added to this collection its ModelElementId will be determined using the ID in the mapping.

Parameters:

modelElementToIdMap - A map containing ModelElementIds for the model element and its children

disallocateModelElementIds

void disallocateModelElementIds(Set<ModelElementId> modelElementIds)

Removes any allocated ID entries from this collection that are contained in the given set of ModelElementIds.

Parameters:

modelElementIds - the set of model element IDs to be released

contains

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

Checks whether a given EObject is contained in the collection.

Specified by:

contains in interface ESObjectContainer<ModelElementId>

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

See Also:

ESObjectContainer.contains(org.eclipse.emf.ecore.EObject)

contains

boolean contains(ModelElementId eObjectId)

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

Specified by:

contains in interface ESObjectContainer<ModelElementId>

Parameters:

eObjectId - 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

See Also:

ESObjectContainer.contains(java.lang.Object)

getModelElementId

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

Retrieve the ESModelElementId of the given model element.

Specified by:

getModelElementId in interface ESObjectContainer<ModelElementId>

Parameters:

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

Returns:

the ESModelElementId of the given model element

See Also:

ESObjectContainer.getModelElementId(org.eclipse.emf.ecore.EObject)

getModelElement

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

Returns the model element with the given ESModelElementId.

Specified by:

getModelElement in interface ESObjectContainer<ModelElementId>

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

See Also:

ESObjectContainer.getModelElement(java.lang.Object)

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.

Specified by:

getModelElements in interface ESObjectContainer<ModelElementId>

Returns:

a list containing the directly contained model elements within the container

See Also:

ESObjectContainer.getModelElements()

deleteModelElement

void deleteModelElement(org.eclipse.emf.ecore.EObject modelElement)

Deletes the given model element from the collection.

Parameters:

modelElement - the model element that should get deleted

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.

Specified by:

getAllModelElements in interface ESObjectContainer<ModelElementId>

Returns:

a set of all model elements contained in the collection

See Also:

ESObjectContainer.getAllModelElements()

getModelElementsByClass

<T extends org.eclipse.emf.ecore.EObject> org.eclipse.emf.common.util.EList<T> getModelElementsByClass(org.eclipse.emf.ecore.EClass modelElementClass,
                                                                                                       org.eclipse.emf.common.util.EList<T> list)

Retrieve a list of model elements of a certain type in the collection that are directly contained in the collection.

Type Parameters:

T - a sub-type of model element

Parameters:

modelElementClass - the EClass

list - a list of model elements, can be empty, but must be of the same type as the modelElementClass indicates.

Returns:

a list of model elements of the given type

initMapping

void initMapping(Map<org.eclipse.emf.ecore.EObject,String> eObjectToIdMap,
                 Map<String,org.eclipse.emf.ecore.EObject> idToEObjectMap)

/** Initializes the ID caches of the project with the given mappings.

Parameters:

eObjectToIdMap - a mapping from EObjects to IDs

idToEObjectMap - the reverse mapping of eObjectToIdMap

initMapping

void initMapping()

Initializes the ID caches of the collection, i.e. the collection will call getModelElements() and for each model element the ModelElementId is fetched via getModelElementId(EObject). Then a mapping between the model element and its ModelElementId is created within the cache.

getIdToEObjectMapping

Map<String,org.eclipse.emf.ecore.EObject> getIdToEObjectMapping()

Returns the ID/EObject mapping where IDs are represented as strings.

This method is mainly provided for convenience and performance reasons, where the ID must be a string.

Returns:

the ID/EObject mapping

getEObjectToIdMapping

Map<org.eclipse.emf.ecore.EObject,String> getEObjectToIdMapping()

Returns the EObject/ID mapping where IDs are represented as strings.

This method is mainly provided for convenience and performance reasons, where the ID must be a string.

Returns:

the EObject/ID mapping
