The IServerResource interface

P4Java represents Helix Server objects (such as changelists, branch mappings, job specs, and so on) to the end user through associated interfaces (such as IChangelist, IBranchSpec, and so on) onto objects within P4Java that mirror or proxy the server-side originals. This means that over time, the P4Java-internal instances of the objects may get out of date with the server originals, or the server originals may need to be updated with corresponding changes made to the P4Java versions.

P4Java’s IServerResource interface is designed to support such proxying and to allow refreshes from the server or updates to the server as necessary. Virtually all useful P4Java objects or interfaces that proxy or represent Helix Server-side objects extend the IServerResource interface, and unless otherwise noted in the individual Javadoc comments, the interface methods can be used to update server- and client-side versions accordingly.
