------------------------------------

             Summary: Add CAS interface method that allows user to obtain a list of Markers
associated with a given CAS
                 Key: UIMA-2478
                 URL: https://issues.apache.org/jira/browse/UIMA-2478
             Project: UIMA
          Issue Type: New Feature
            Reporter: Benjamin Segal


Add a convenience function that removes the need for applications that create Markers for
many CASes to separately manage them (e.g., map CAS to its related Marker), and thereby simplify
application code.

Today's current level of support allows a user to create a Marker for a given CAS (through
the createMarker() method which is part of the CAS interface).

This proposed support will allow the user to subsequently query a given CAS and obtain a complete
list of Markers created against this CAS. This function is a natural extension to the given
level of support (i.e., if one can create Marker for a given CAS, one should be able to query
the CAS to find said Marker.)

Having this support significant simplifies application code, offering advantages from a memory
overhead, performance, and maintainability standpoint.  For example, the application won't
need to build and maintain a map of CASes to Markers, given the Marker is hanging off the
CAS to begin with.
