    • run

      public V run(T operation) throws SVNException
      Description copied from interface: ISvnOperationRunner
      Implementation of operation's run method for concrete working copy generation
      Specified by:
      run in interface ISvnOperationRunner<V,T extends SvnOperation<V>>
      Parameters:
      operation - operation that needs to be executed
      Returns:
      execution result value of operation's return type
      Throws:
      SVNException
    • reset

      public void reset(SvnWcGeneration wcGeneration)
      Description copied from interface: ISvnOperationRunner
      Resets runner's working copy generation.
      Specified by:
      reset in interface ISvnOperationRunner<V,T extends SvnOperation<V>>
      Parameters:
      wcGeneration - new working copy generation for the runner
    • setWcContext

      public void setWcContext(SVNWCContext context)
      Description copied from interface: ISvnOperationRunner
      Sets operation's context
      Specified by:
      setWcContext in interface ISvnOperationRunner<V,T extends SvnOperation<V>>
      Parameters:
      context - context of the operation
    • getWcContext

      protected SVNWCContext getWcContext()
    • run

      protected abstract V run() throws SVNException
      Throws:
      SVNException
    • setOperation

      public void setOperation(T operation)
    • getOperation

      public T getOperation()
    • checkCancelled

      public void checkCancelled() throws SVNCancelException
      Description copied from interface: ISVNCanceller
      Checks if the current operation is cancelled (somehow interrupted) and should throw an SVNCancelException or notify the handler if exists.

      This method is often called during iterations when processing trees of versioned items. This way the entire operation may be interrupted without waiting till the iteration run out.

      Specified by:
      checkCancelled in interface ISVNCanceller
      Throws:
      SVNCancelException
    • handleEvent

      public void handleEvent(SVNEvent event, double progress) throws SVNException
      Description copied from interface: ISVNEventHandler
      Handles the current event.

      Generally all operations represented by do*() methods of SVN*Client objects are followed by generating a sequence of events that are passed to the registered ISVNEventHandler object for custom processing. For example, during an update operation each local item being modified is signaled about by dispatching a specific for this item SVNEvent object to this method where this event can be scrutinized and handled in a desired way.

      Specified by:
      handleEvent in interface ISVNEventHandler
      Parameters:
      event - the current event that keeps detailed information on the type of action occured and other attributes like path, status, etc.
      progress - currently reserved for future use; now it's value is always set to ISVNEventHandler.UNKNOWN
      Throws:
      SVNException
    • handleEvent

      protected void handleEvent(SVNEvent event) throws SVNException
      Throws:
      SVNException
