Examples of org.apache.uima.cas.TypeSystem

org.apache.uima.cas.TypeSystem
The interface to the type system. Used to access information about existing {@link org.apache.uima.cas.Type types} and {@link org.apache.uima.cas.Feature features} usingtheir String identifiers. This is a pure access interface. Types and features are defined using Component Descriptors, written in XML.
Get the type system from a {@link CAS CAS} object with {@link CAS#getTypeSystem getTypeSystem()}.
There are a few methods to list the existing types in a type system. Information about which feature is appropriate for which type is available through the {@link Type Type} and{@link Feature Feature} classes.

      // now read in a TypeSystem that's a subset of those types
      TypeSystemDescription partialTypeSystemDesc = UIMAFramework.getXMLParser()
              .parseTypeSystemDescription(
                      new XMLInputSource(JUnitExtension
                              .getFile("ExampleCas/partialTestTypeSystem.xml")));
      TypeSystem partialTypeSystem = CasCreationUtils.createCas(partialTypeSystemDesc, null, null)
              .getTypeSystem();


      // reserialize as XMI, filtering out anything that doesn't fit in the
      // partialTypeSystem
      StringWriter sw = new StringWriter();
