    • begin

      public void begin(ExtensionsManager manager, int numFiles)
      Description copied from interface: ExtensionsFileProcessor
      Called by the extensions manager before the processing starts.
      Specified by:
      begin in interface ExtensionsFileProcessor
      Parameters:
      manager - The manager that is executing the action
      numFiles - The number of extension files that is going to be processed this time

    • processFile

      public void processFile(ExtensionsManager manager, ExtensionsFile.WriteableExtensionsFile wFile)
      Description copied from interface: ExtensionsFileProcessor
      Called by the extensions manager for each extensions file that it manages. The order of the files is generally not predicatable and may change from one invokation to the next.

      If the processor throws an exception the manager will abort processing and call ExtensionsFileProcessor.done(ExtensionsManager, Throwable). Error that are related to a specific file should be catched by the processor and registered by calling .......

      If all files was processed without exceptions the manager will call ExtensionsFileProcessor.done(ExtensionsManager).

      Note that the file is read-only to begin with. If the processor wants to call any write-operation the file must be opened by calling ExtensionsFile.WriteableExtensionsFile.open(). It is recommended that the processor calls ExtensionsFile.WriteableExtensionsFile.close() once it is done writing.

      Specified by:
      processFile in interface ExtensionsFileProcessor
      Parameters:
      manager - The manager that is executing the action
