getEObjectById

ChronoEObject getEObjectById(java.lang.String eObjectID)

Retrieves a single ChronoEObject by its unique identifier.

Parameters:

eObjectID - The ID of the EObject to retrieve. Must not be null.

Returns:

The EObject. May be null if there is no EObject for the given ID.

getEObjectById

java.util.Map<java.lang.String,ChronoEObject> getEObjectById(java.lang.Iterable<java.lang.String> eObjectIDs)

Retrieves the ChronoEObjects for the given unique identifiers.

Parameters:

eObjectIDs - The IDs of the EObjects to retrieve. May be empty, but must not be null.

Returns:

The mapping from unique ID to retrieved EObject. May be empty, but never null. Is guaranteed to include every given ID as a key. The IDs that did not have a matching EObject have null values assigned in the map.

getEObjectById

java.util.Map<java.lang.String,ChronoEObject> getEObjectById(java.util.Iterator<java.lang.String> eObjectIDs)

Retrieves the ChronoEObjects for the given unique identifiers.

Parameters:

eObjectIDs - The IDs of the EObjects to retrieve. May be empty, but must not be null.

Returns:

The mapping from unique ID to retrieved EObject. May be empty, but never null. Is guaranteed to include every given ID as a key. The IDs that did not have a matching EObject have null values assigned in the map.

find

QueryStepBuilderStarter find()

getEObjectHistory

java.util.Iterator<java.lang.Long> getEObjectHistory(org.eclipse.emf.ecore.EObject eObject)

Returns an iterator over the change timestamps in the history of the given EObject.

Parameters:

eObject - The eObject in question. Must not be null.

Returns:

An iterator over the change timestamps, in descending order. May be empty if the given object is not attached.

getEObjectModificationsBetween

java.util.Iterator<org.apache.commons.lang3.tuple.Pair<java.lang.Long,java.lang.String>> getEObjectModificationsBetween(long timestampLowerBound,
                                                                                                                        long timestampUpperBound)

Returns an iterator over all EObject modifications that have taken place in the given time range.

Parameters:

timestampLowerBound - The lower bound of the time range to search in. Must not be negative. Must be less than or equal to timestampUpperBound. Must be less than or equal to the transaction timestamp.

timestampUpperBound - The upper bound of the time range to search in. Must not be negative. Must be greater than or equal to timestampLowerBound. Must be less than or equal to the transaction timestamp.

Returns:

An iterator over pairs, containing the change timestamp at the first and the modified EObject id at the second position. May be empty, but never null.
