static NodeOperation	addNode(String name, String type)
static NodeOperation	addProperty(String name, String newValue) Adds property.
static NodeOperation	getNode(String name)

Method Detail

addNode

public static NodeOperation addNode(String name)

addNode

public static NodeOperation addNode(String name,
                                    String type)

getNode

public static NodeOperation getNode(String name)

addProperty

public static NodeOperation addProperty(String name,
                                        String newValue)

Adds property. Throws an ItemExistsException if the property already exists.

setProperty

public static NodeOperation setProperty(String name,
                                        Object newValue)

Sets the value of an existing property, ignoring its current value.

Throws:

javax.jcr.ItemNotFoundException - if the property does not exist.

renameNode

public static NodeOperation renameNode(String currentName,
                                       String newName)

Renames a node.

renameProperty

public static NodeOperation renameProperty(String name,
                                           String newName)

Renames a property by creating a new one and copying the value.

moveNode

public static NodeOperation moveNode(String nodeName,
                                     String dest)

Moves a node, using session-scoped operation.

noop

public static NodeOperation noop()

No operation; can be useful in ternary expression, for instance.

getOrAddNode

public static final NodeOperation getOrAddNode(String name,
                                               String nodeType)

Gets or adds node depending on whether it existed or not.

onChildNodes

public static final NodeOperation onChildNodes()

Executes then() ops on all child nodes. Use with care as it might result in modification of more nodes then intended.

onChildNodes

public static final NodeOperation onChildNodes(AbstractPredicate<javax.jcr.Node> predicate)

Executes then() ops on all child nodes that are evaluated true by the predicate.

ifTrue

public static final NodeOperation ifTrue(boolean bool)

Executes all then() defined ops only when passed in flag is evaluated true, behaves as noop otherwise. This is useful to switch off/on blocks of bigger operation chains without having to split them into too many small chunks.
