Method Detail

getDataNode

javax.jcr.Node getDataNode(javax.jcr.Node rootNode,

                    throws javax.jcr.PathNotFoundException,
                           javax.jcr.RepositoryException

Retrieves the node from the JCR under the given root node and corresponding to the given data id.

Parameters:

rootNode - the root node under which the data to find is stored

dataId - the id of the data to find

Returns:

the Node corresponding to the data to find

Throws:

javax.jcr.PathNotFoundException - if the data cannot be find

javax.jcr.RepositoryException - if an error occurred while trying to get the expected data

getOrCreateDataNode

javax.jcr.Node getOrCreateDataNode(javax.jcr.Node rootNode,
                                   String dataId)
                            throws javax.jcr.RepositoryException

Tries to get the node from the JCR and if it cannot be found, it will create it automatically.

Parameters:

rootNode - the root node under which the data to find is stored

dataId - the id of the data to find/create

Returns:

the Node corresponding to the data to find

Throws:

javax.jcr.RepositoryException - if an error occurred while trying to get or create the expected data

getOrCreateDataNode

javax.jcr.Node getOrCreateDataNode(javax.jcr.Node rootNode,
                                   String dataId,
                                   String nodeType)
                            throws javax.jcr.RepositoryException

Tries to get the node from the JCR and if it cannot be found, it will create it automatically. If the node has to be created, the node will be created with the given node type.

Parameters:

rootNode - the root node under which the data to find is stored

dataId - the id of the data to find/create

nodeType - the node type to use in case we need to create the node

Returns:

the Node corresponding to the data to find

Throws:

javax.jcr.RepositoryException - if an error occurred while trying to get or create the expected data

getOrCreateDataNode

javax.jcr.Node getOrCreateDataNode(javax.jcr.Node rootNode,
                                   String dataId,

dataId - the id of the data to find/create

nodeType - the node type to use in case we need to create the node

mixinTypes - the mixin types to use in case we need to create the node

Returns:

the Node corresponding to the data to find

Throws:

javax.jcr.RepositoryException - if an error occurred while trying to get or create the expected data

getOrCreateDataNode

permissions - the permissions to use in case we need to create the node

Returns:

the Node corresponding to the data to find

Throws:

javax.jcr.RepositoryException - if an error occurred while trying to get or create the expected data

removeDataNode

void removeDataNode(javax.jcr.Node rootNode,
                    String dataId)
