Interface EPackageToGraphMapper

All Known Implementing Classes:

EPackageToGraphMapperImpl

public interface EPackageToGraphMapper

This class is a utility capable of mapping EPackages to the graph, and reading the ChronoEPackageRegistry from the graph.

Method Summary

Modifier and Type	Method and Description
void	deleteInGraph(org.chronos.chronograph.api.structure.ChronoGraph graph, EPackageBundle bundle) Removes the graph representation of the given EPackageBundle, as well as all EObjects that are instances of the classifiers contained within the bundle.
void	mapToGraph(org.chronos.chronograph.api.structure.ChronoGraph graph, EPackageBundle bundle) Maps the contents of the given EPackageBundle into the given ChronoGraph.
ChronoEPackageRegistry	readChronoEPackageRegistryFromGraph(org.chronos.chronograph.api.structure.ChronoGraph graph) Reads the contents of the given ChronoEPackageRegistry from the graph.

Method Detail

mapToGraph

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

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!

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

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

Reads the contents of the given ChronoEPackageRegistry from the graph.

Parameters:

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

Returns:

The ChronoEPackageRegistry. Never null.

deleteInGraph

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

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.

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.
