Method Detail

isNodeType

public static boolean isNodeType(javax.jcr.Node node,
                                 String type)
                          throws javax.jcr.RepositoryException

Determine whether node is of the specified type, by using the jcr:mixinTypes property. This is necessary when a mixin has been added to the node, but the node hasn't been saved yet.

Parameters:

node -

type -

Returns:

true when the node is of the specified type

Throws:

javax.jcr.RepositoryException

getVersionParent

public static javax.jcr.version.Version getVersionParent(javax.jcr.version.Version version)
                                                  throws javax.jcr.ItemNotFoundException,
                                                         javax.jcr.RepositoryException

Find the first checked-in version of the parent of a node that contains a particular version of the child. I.e. given a version of a child, the oldest version of the parent that contains the child is returned.

Parameters:

version -

Throws:

javax.jcr.ItemNotFoundException

javax.jcr.RepositoryException

getPrimaryItem

public static javax.jcr.Item getPrimaryItem(javax.jcr.Node node)
                                     throws javax.jcr.ItemNotFoundException,
                                            javax.jcr.RepositoryException

Retrieve the primary item of a node, according to the primary node type hierarchy. Plain JackRabbit only checks the declared items of a type, not the inherited ones.

Parameters:

node -

Returns:

primary item

Throws:

javax.jcr.ItemNotFoundException

javax.jcr.RepositoryException

isVirtualNode

public static boolean isVirtualNode(javax.jcr.Node node)
                             throws javax.jcr.RepositoryException

Determine whether node in question is a virtual node.

Parameters:

node - the node to check for virtuality

Returns:

whether the node is a virtual node or not

Throws:

javax.jcr.RepositoryException

isVirtualRoot

public static boolean isVirtualRoot(javax.jcr.Node node)
                             throws javax.jcr.RepositoryException

Determine whether the node is a virtual root node (facet search or facet navigation)

Parameters:

node -

Throws:

javax.jcr.RepositoryException
