public AbstractNeoSaveProcessor()

Method Detail

setHelper

public void setHelper(NeoHelper neoHelper)

Setter.

Parameters:

neoHelper - the helper to set

getHelper

public NeoHelper getHelper()

Getter.

Returns:

the helper

process

public void process(org.eclipse.emf.ecore.resource.Resource resource,
                    Map<org.eclipse.emf.ecore.EObject,Object> registry)

Process.

Specified by:

process in interface SaveProcessor

Parameters:

resource - Resource

registry - Node cache

See Also:

SaveProcessor.process(org.eclipse.emf.ecore.resource.Resource, java.util.Map)

public void dispatch(org.eclipse.emf.ecore.EObject element,
                     Map<org.eclipse.emf.ecore.EObject,Object> registry)

Dispatch the current element to its handler.

The order of dispatch types dependends on type hierarchy. Special types must be checked earlier then generally types.

Specified by:

dispatch in interface SaveProcessor

Parameters:

element - Element to dispatch

registry - Node cache

getNodeFromRegistry

protected org.neo4j.api.core.Node getNodeFromRegistry(org.eclipse.emf.ecore.EObject element,
                                                      Map<org.eclipse.emf.ecore.EObject,Object> registry)

Determine a node from the registry.

Parameters:

element - Element for what we need a node.

registry - Node cache

Returns:

Node

createNodeWithRelationship

protected org.neo4j.api.core.Node createNodeWithRelationship(org.neo4j.api.core.Node node,
                                                             EcoreRelationshipType relType,
                                                             boolean ordered)

Parameters:

node - the node

relType - the relationship type

ordered - true if node will be created with ordering position value

Returns:

the created and bound node

createNode

protected org.neo4j.api.core.Node createNode()

Create a node. Optionally the node gets a position ordering value.

Returns:

Node
