isNodeType

public static boolean isNodeType(Node node,
                                 String type)
                          throws 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:

RepositoryException

getVersionParent

public static Version getVersionParent(Version version)
                                throws ItemNotFoundException,
                                       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:

ItemNotFoundException

RepositoryException

getPrimaryItem

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

Parameters:

node -

Returns:

primary item

Throws:

ItemNotFoundException

RepositoryException

isVirtualNode

public static boolean isVirtualNode(Node node)
                             throws 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:

RepositoryException

isVirtualRoot

public static boolean isVirtualRoot(Node node)
                             throws RepositoryException

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

Parameters:

node -

Throws:
