Modifier and Type	Method and Description
org.eclipse.emf.transaction.TransactionalEditingDomain	createResourceSetAndEditingDomain() Creates a TransactionalEditingDomain with a ResourceSet resource set and a IWorkspaceCommandStack command stack.
Diagram	getDiagramFromFile(IFile file, org.eclipse.emf.ecore.resource.ResourceSet resourceSet) If given file is a valid emf resource and it contains a diagram as first root element, this methods return the diagram.
org.eclipse.emf.ecore.EObject	getEObject(java.lang.Object object) Tries to convert the given object to a EObject using #adaptObject(Object, Class), unwrapping an IStructuredSelection.

IFile	getFile(org.eclipse.emf.common.util.URI uri) Returns the Eclipse file for the given URI.
org.eclipse.emf.common.util.URI	getFileURI(IFile file) Retrieves the workspace-local string location of the given IFile, constructs a potentially normalized platform resource URI from it and returns it.
java.lang.String	getObjectName(java.lang.Object obj) Returns the human readable name of a given object or the EMF id if no name can be found.
org.eclipse.emf.common.util.URI	mapDiagramFileUriToDiagramUri(org.eclipse.emf.common.util.URI diagramFileUri) Maps the fileURI to an URI which points directly to the Diagram Object.
java.lang.StringBuilder	toString(org.eclipse.emf.ecore.EObject o, java.lang.StringBuilder result) Creates an extended string presentation of the given EObject, including its type and attributes

Method Detail

getObjectName

public java.lang.String getObjectName(java.lang.Object obj)

Description copied from interface: IEmfService

Returns the human readable name of a given object or the EMF id if no name can be found. The method tries to access a modeled attribute "name" or "id" in this order. If no attribute with this name is modeled, the first attribute whose value is a String or TranslatableTextFragment is returned, otherwise null .

Parameters:

obj - the object to get a name for

Returns:

the value of attribute "name" or the EMF id if no attribute "name" exists

getEObject

public org.eclipse.emf.ecore.EObject getEObject(java.lang.Object object)

Description copied from interface: IEmfService

Tries to convert the given object to a EObject

• using #adaptObject(Object, Class),
• unwrapping an IStructuredSelection.

Parameters:

object - the object to convert

Returns:

the target object or null

See Also:

IEmfService.getEObject(Object)

getFile

public IFile getFile(org.eclipse.emf.ecore.EObject object)

Description copied from interface: IEmfService

Returns the Eclipse file for the given EObject's Resource . Note that the file is null for objects in

• archives,
• closed projects,
• not yet persisted resources or not yet persisted EObjects in already persisted resources. In this respect this methods behaves asymmetric to the handle-only resource APIs like IProject.getFile(String).

Parameters:

object - the model object to get the file for

Returns:

the partition file or null under the mentioned circumstances

See Also:

IEmfService.getFile(URI)

getFile

public IFile getFile(org.eclipse.emf.common.util.URI uri)

Description copied from interface: IEmfService

Returns the Eclipse file for the given URI. Note that the file is null for objects in

• archives,
• closed projects,
• not yet persisted resources or not yet persisted EObjects in already persisted resources. In this respect this methods behaves asymmetric to the handle-only resource APIs like IProject.getFile(String).

Parameters:

uri - the URI to get the file for

Returns:

the file or null under the mentioned circumstances

See Also:

IEmfService.getFile(EObject)

toString

public java.lang.StringBuilder toString(org.eclipse.emf.ecore.EObject o,
                                        java.lang.StringBuilder result)

Description copied from interface: IEmfService

Creates an extended string presentation of the given EObject, including its type and attributes

Parameters:

o - the object to create a string presentation for

result - the string buffer to store the result into

Returns:

the same string buffer as result per convenience

See Also:

#toString(EObject)

getDiagramFromFile

public Diagram getDiagramFromFile(IFile file,
                                  org.eclipse.emf.ecore.resource.ResourceSet resourceSet)

Description copied from interface: IEmfService

If given file is a valid emf resource and it contains a diagram as first root element, this methods return the diagram. Otherwise this method returns null.

Parameters:

file - a valid emf (diagram) resource

Returns:

diagram or null

getFileURI

public org.eclipse.emf.common.util.URI getFileURI(IFile file)

Description copied from interface: IEmfService

Retrieves the workspace-local string location of the given IFile, constructs a potentially normalized platform resource URI from it and returns it.

Parameters:

file - The file to construct the URI for

Returns:

The platform resource URI for the given file.

mapDiagramFileUriToDiagramUri

public org.eclipse.emf.common.util.URI mapDiagramFileUriToDiagramUri(org.eclipse.emf.common.util.URI diagramFileUri)

Description copied from interface: IEmfService

Maps the fileURI to an URI which points directly to the Diagram Object. This methods assumes the Diagram object is the first root object in the given file.

Parameters:

diagramFileUri - URI of the diagramFile

Returns:

URI of the diagram

createResourceSetAndEditingDomain

public org.eclipse.emf.transaction.TransactionalEditingDomain createResourceSetAndEditingDomain()

Description copied from interface: IEmfService

Creates a TransactionalEditingDomain with a ResourceSet resource set and a IWorkspaceCommandStack command stack.

Specified by:

createResourceSetAndEditingDomain in interface IEmfService

Returns:

a TransactionalEditingDomain editing domain
