      Description copied from interface: VariableListener
      Called when a variable's values are updated
      Specified by:

    • fireEmission

      protected void fireEmission​(int size)
      Fires a source emission of size size, and updates the cursor.
      Parameters:
      size -

    • fireReset

      protected void fireReset()
      Informs listeners that this data source has been reset (i.e., the XY signal history should be destroyed.

    • setBatch

      public void setBatch​(boolean b)
      Informs this data source to treat all subsequent operations as a batch job; i.e., do not fire any events. Events will be fired, if necessary, when this method is called with b == false.
      Parameters:
      b -

    • reset

      public void reset() throws java.io.IOException
      Resets this data source.
      Throws:
      java.io.IOException

    • setChannel

      public void setChannel​(MatrixInt matrix)
      Sets a channel for this data source; uses the object's name as the channel name. If a channel by this name doesn't already exist, creates it; otherwise overwrites it. Finally, fires an emission event to alert listeners of this change.
      Parameters:
      matrix -

    • removeChannel

      public void removeChannel​(java.lang.String channel)
      Removes a channel for this data source.
      Parameters:
      channel -
