Resource Locking Custom Protocol Plugin Extension

This plugin type allows the developer to work with a custom designed protocol for retrieving and storing files. It can lock a resource on opening it in Oxygen XML Author. This type of plugin extends the custom protocol plugin type with resource locking support.

Such a plugin provides the following API:

• The interface URLStreamHandlerWithLockPluginExtension - The plugin receives callbacks following the simple protocol for resource locking and unlocking imposed by Oxygen XML Author.

  There are two additional methods that must be implemented:

  • getLockHandler() - Returns a LockHandler implementation class with the implementation of the lock specific methods from the plugin.
  • isLockingSupported(String protocol) - Returns a boolean that is true if the plugin accepts to manage locking for a certain URL protocol scheme like ftp, http, https, or customName.
