Method Detail

getSingleElement

org.eclipse.xtext.resource.IEObjectDescription getSingleElement(org.eclipse.xtext.naming.QualifiedName name,
                                                                Collection<ISliceFilter> slices)

Finds the first description that matches the given name.

Parameters:

name - the name of the to-be-found element. May not be null.

slices - list of predicates corresponding to the index slices, can't be null

Returns:

the first element that matches the name. May be null.

getElements

Iterable<org.eclipse.xtext.resource.IEObjectDescription> getElements(org.eclipse.xtext.naming.QualifiedName name,
                                                                     Collection<ISliceFilter> slices)

Find all descriptions that match the given name.

Parameters:

name - the name of the to-be-found elements. May not be null.

slices - list of predicates corresponding to the index slices, can't be null

Returns:

all elements that match the name. Never null.

getAllElements

Iterable<org.eclipse.xtext.resource.IEObjectDescription> getAllElements(Collection<ISliceFilter> slices)

Obtain all elements from the scope. Implementors a free to throw an UnsupportedOperationException if the scope cannot be enumerated.

Parameters:

slices - list of predicates corresponding to the index slices, can't be null

Returns:

all elements of the scope. Never null.

Throws:

UnsupportedOperationException - if the scope cannot be enumerated.

getElements

Iterable<org.eclipse.xtext.resource.IEObjectDescription> getElements(org.eclipse.emf.ecore.EObject object,
                                                                     Collection<ISliceFilter> slices)

Finds all descriptions that match the given instance.

Parameters:

object - the instance whose descriptions should be obtained. May not be null.

slices - list of predicates corresponding to the index slices, can't be null

Returns:

all elements that match the instance. Never null.
