    public interface AbstractCas

The base interface extended by all CAS (Common Analysis System) interfaces in the UIMA SDK. A CAS is an object that provides access to an artifact and metadata about that artifact. Analysis Components, such as Annotators, read from a CAS interface in order to do their analysis and may write new metadata back to the CAS interface.

The UIMA SDK provides the CAS interfaces `JCas` and `CAS`, but in future versions, other CAS interfaces may be available.
