Class TransDebugMeta

  • public class TransDebugMeta
extends Object
    For a certain transformation, we want to be able to insert break-points into a transformation. These breakpoints can be applied to steps. When a certain condition is met, the transformation will be paused and the caller will be informed of this fact through a listener system.
