getNodeTypeName

public static String getNodeTypeName(javax.jcr.Node node)
                              throws javax.jcr.RepositoryException

Return the NodeType-name for the provided Node. It it's a JCPropertiesFilteringNodeWrapper the unwrapped node will be used for retrieving the property from. As it's about versioning, the frozen primary type if existing (else primary type) will be returned.

Throws:

javax.jcr.RepositoryException

getVersionInfoList

public static List<VersionInfo> getVersionInfoList(javax.jcr.Node node)

Returns version history of a content as a List of VersionInfos.

Parameters:

node - Node

Returns:

list of version info
