Method Detail

createRootNodeState

protected VirtualNodeState createRootNodeState()
                                        throws RepositoryException

Creates the root node state.

currently we have no dynamic ones, we just recreate the entire nodetypes tree

Specified by:

createRootNodeState in class AbstractVISProvider

Returns:

The virtual root node state.

Throws:

RepositoryException

internalHasNodeState

protected boolean internalHasNodeState(NodeId id)

Checks if this provide has the node state of the given node id

Specified by:

internalHasNodeState in class AbstractVISProvider

Returns:

true if it has the node state

internalGetNodeState

protected VirtualNodeState internalGetNodeState(NodeId id)
                                         throws NoSuchItemStateException,
                                                ItemStateException

Retrieves the node state with the given node id

Specified by:

internalGetNodeState in class AbstractVISProvider

Returns:

Throws:

NoSuchItemStateException

ItemStateException

onNodeTypeAdded

public void onNodeTypeAdded(Name ntName)

onNodeTypeModified

public void onNodeTypeModified(Name ntName)

onNodeTypesRemoved

public void onNodeTypesRemoved(Collection<Name> names)

setNodeReferences

public boolean setNodeReferences(ChangeLog references)

Description copied from interface: VirtualItemStateProvider

Informs this provider that the node references to some of its states have changed.

Parameters:

references - collection of NodeReferences instances

Returns:

true if the reference target is one of its items.
