Examples of org.apache.uima.cas.AbstractCas

org.apache.uima.cas.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 {@link org.apache.uima.jcas.JCas} and{@link org.apache.uima.cas.CAS}, but in future versions, other CAS interfaces may be available.

      Class<? extends AbstractCas> casInterface) {
    CASImpl ci = getStartingView(cas, sofaAware, componentInfo);
    // get requested interface to CAS (CAS or JCas)
    // next will create JCas if needed, but not already created
    // must precede the switchClassLoader call - that one needs the JCas link, if it is being used
    AbstractCas r = CasManager_impl.getCasInterfaceStatic(ci, casInterface);
    // This cas will be unlocked and its class loader restored when the
    //   next() method returns it
    // Insure the same view is passed for switching/restoring  https://issues.apache.org/jira/browse/UIMA-2211
