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)
                     throws ClientException
```
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

ClientException

getTransientGraph
```
Graph getTransientGraph(String type)
                        throws ClientException
```
Gets a transient graph.

Parameters:
type - The graph type.

Returns:
the graph.

Throws:

ClientException

getResource
```
Resource getResource(String namespace,
                   Serializable object,
                   Map<String,Object> context)
                     throws ClientException
```
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.

Throws:

ClientException
Since:

5.2-M1

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

Throws:

ClientException
Since:

5.2-M1

getResourceRepresentation

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

Gets an object representing this resource given a namespace.

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

Throws:: ClientException
Since:: 5.2-M1

getGraphNames
```
List<String> getGraphNames()
                           throws ClientException
```
Gets the list containing the graph names.

Throws:

ClientException
Since:

5.2-GA
