Method Detail

isNode

public boolean isNode()

Always returns false.

Specified by:

isNode in class ItemState

Returns:

always false

getId

public ItemId getId()
             throws javax.jcr.RepositoryException

Utility method: Returns the identifier of this item state. Shortcut for calling 'getId' on the hierarchy entry.

Specified by:

getId in class ItemState

Returns:

the identifier of this item state..

Throws:

javax.jcr.RepositoryException

getWorkspaceId

public ItemId getWorkspaceId()
                      throws javax.jcr.RepositoryException
