Examples of org.apache.jackrabbit.spi.Name

org.apache.jackrabbit.spi.Name
A Name is a combination of a namespace URI and a local part. Instances of this class are used to internally represent the names of JCR content items and other objects within a content repository.
A Name is immutable once created.
The String representation of a Name object must be in the format "{namespaceURI}localPart".
An implementation of the Name interface must implement the {@link Object#equals(Object)} method such that two Name objects are equal ifboth the namespace URI and the local part are equal.
