Using the Marking Property to Define Segment Boundaries

Using the Marking Property to Define Segment Boundaries

You can use the marking property to control whether the data in the opening and closing marker is included in the segment and passed to a transformation.
The rule is that the Streamer passes the data between the innermost reference points surrounding the segment. For example:
  • If the opening marker has
    marker = begin position
    , the innermost reference point is at the start. The entire marker is included in the segment.
  • If the opening marker has
    marker = end position
    or
    full
    , the innermost reference point is at the end. The marker is excluded from the segment.
The inverse relationships apply to the closing marker.
To illustrate this, consider a simple segment having the following structure:
BEGIN...data...END
A
MarkerStreamer
identifies the opening marker by searching for the text
BEGIN
. Another
MarkerStreamer
identifies the closing marker by searching for
END
.
The following table illustrates how the marking property affects the segment boundaries.
