Method Detail

getGraph

Graph getGraph(String name,
               CoreSession session)

Gets a registered graph by name.

A CoreSession should be passed to provide a context in which to store relations when using a "core" graph.

Parameters:

name - string name of the graph used at registration

session - the core session

Returns:

the graph

Throws:

RuntimeException - if the graph is not found

Since:

5.5

getGraphByName

Graph getGraphByName(String name)

Gets a registered graph by name.

Parameters:

name - string name of the graph used at registration

Returns:

the graph

Throws:

RuntimeException - if the graph is not found

getTransientGraph

Graph getTransientGraph(String type)

Gets a transient graph.

Parameters:

type - The graph type.

Returns:

the graph.

getResource

Resource getResource(String namespace,
                     Serializable object,
                     Map<String,Object> context)

Gets a resource given a namespace and a serializable object.

There can be several resources with different namespaces associated to an incoming object. A document can for instance be used to refer to itself as a precise version as well as to the set of all versions.

Context can hold any object useful for the adapters, like a CoreSession.

Since:

5.2-M1

getAllResources

Set<Resource> getAllResources(Serializable object,
                              Map<String,Object> context)

Computes all resources corresponding to the given object.

Context can hold any object useful for the adapters, like a CoreSession.

Returns:

the resources as a set

Since:

5.2-M1

getResourceRepresentation

Serializable getResourceRepresentation(String namespace,
                                       Resource resource,
                                       Map<String,Object> context)

Gets an object representing this resource given a namespace.

Context can hold any object useful for the adapters, like a CoreSession.

Since:

5.2-M1

getGraphNames

List<String> getGraphNames()

Gets the list containing the graph names.

Since:

5.2-GA
