Method Detail

mapToGraph

public void mapToGraph(org.chronos.chronograph.api.structure.ChronoGraph graph,
                       EPackageBundle bundle)

Description copied from interface: EPackageToGraphMapper

Maps the contents of the given EPackageBundle into the given ChronoGraph.

After this operation, the contents of the graph will fully reflect the contents of the given EPackageBundle. The graph will be adapted, the bundle is treated as read-only.

/!\ WARNING: If an EClass or (sub-) package was removed, the instances will be deleted as well!

Specified by:

mapToGraph in interface EPackageToGraphMapper

Parameters:

graph - The graph to map the EPackageBundle into. Must not be null. Must be self-contained.

bundle - The bundle to synchronize with the graph. Will be treated as read-only. Must not be null.

readChronoEPackageRegistryFromGraph

public ChronoEPackageRegistry readChronoEPackageRegistryFromGraph(org.chronos.chronograph.api.structure.ChronoGraph graph)

Description copied from interface: EPackageToGraphMapper

Reads the contents of the given ChronoEPackageRegistry from the graph.

Specified by:

readChronoEPackageRegistryFromGraph in interface EPackageToGraphMapper

Parameters:

graph - The graph to read from. Must not be null.

Returns:

The ChronoEPackageRegistry. Never null.

deleteInGraph

public void deleteInGraph(org.chronos.chronograph.api.structure.ChronoGraph graph,
                          EPackageBundle bundle)

Description copied from interface: EPackageToGraphMapper

Removes the graph representation of the given EPackageBundle, as well as all EObjects that are instances of the classifiers contained within the bundle.

This is an expensive operation. Use with care.

Specified by:

deleteInGraph in interface EPackageToGraphMapper

Parameters:

graph - The graph to perform the deletion in. Must not be null.

bundle - The EPackageBundle to delete in the graph. Must not be null.
