Method Detail

iterator

public Iterator<javax.jcr.Node> iterator()

Description copied from interface: Sequence

Iterator for the Items in this sequence. The order of the items is implementation specific.

Specified by:

iterator in interface Iterable<javax.jcr.Node>

Specified by:

iterator in interface Sequence<javax.jcr.Node>

Iterable.iterator()

getItem

public javax.jcr.Node getItem(String key)
                       throws javax.jcr.RepositoryException

Description copied from interface: Sequence

Retrieve an Item from this sequence by its key. If the sequence does not contain the key this method throws an ItemNotFoundException.

Specified by:

getItem in interface Sequence<javax.jcr.Node>

Parameters:

key - The key of the item to retrieve. Must not be null.

Returns:

The item belonging to key.

Throws:

javax.jcr.ItemNotFoundException

javax.jcr.RepositoryException

hasItem

public boolean hasItem(String key)
                throws javax.jcr.RepositoryException

Description copied from interface: Sequence

Determine whether this sequence contains a specific key.

Specified by:

hasItem in interface Sequence<javax.jcr.Node>

Parameters:

key - The key to look up.

Returns:

true if this sequence contains key. False otherwise.

Throws:

javax.jcr.RepositoryException

addNode

public javax.jcr.Node addNode(String key,
                     String primaryNodeTypeName)
                       throws javax.jcr.RepositoryException

Description copied from interface: NodeSequence

Add a with the given key and primary node type name.

Specified by:

addNode in interface NodeSequence

Parameters:

key - key of the node to add

primaryNodeTypeName - primary node type of the node to add

Returns:

the newly added node

Throws:

javax.jcr.RepositoryException

removeNode

public void removeNode(String key)
                throws javax.jcr.RepositoryException

Description copied from interface: NodeSequence

Remove the node with the given key.

Specified by:

removeNode in interface NodeSequence

Parameters:

key - The key of the node to remove

Throws:

javax.jcr.RepositoryException - If there is no node with such a key or another error occurs.

getParent

public javax.jcr.Node getParent(String key)
                         throws javax.jcr.RepositoryException

Description copied from class: ItemSequence

Returns the parent node for the given key. When the key is not present in this sequence already, the returned node is the node that would contain that key if it where present.

Specified by:

getParent in class ItemSequence

Throws:

javax.jcr.RepositoryException
