• JCasRegistry

  public JCasRegistry()

Method Detail

• register

  public static int register(Class<? extends TOP> aJCasCoverClass)

  Registers a JCas cover class with this registry. The registry will assign it a unique index, which is then used by the cover-class to identify itself to the JCas implementation.

  Parameters:

  aJCasCoverClass - the class to register

  Returns:

  the unique index value for this class.

• getFeatOkTst

  public static boolean getFeatOkTst(String fullyQualTypeName)

  For a particular type, return true if that type should have run-time checking for use of fields defined in the JCas Model which are not present in the CAS. If false, all fields in the JCas must be in the CAS type system at instantiation time, or an exception is thrown; this allows the runtime to skip this test.

  This is reserved for future use; it currently always returns true.

  Parameters:

  fullyQualTypeName - fully qualified type name

  Returns:

  true if that type should have run-time checking for use of fields defined in the JCas Model which are not present in the CAS. If false, all fields in the JCas must be in the CAS type system at instantiation time, or an exception is thrown; this allows the runtime to skip this test.

• getNumberOfRegisteredClasses

  public static int getNumberOfRegisteredClasses()

  Gets the number of cover classes that have been registered.

  Returns:

  the number of registered JCas cover classes

• getClassForIndex

  public static Class<? extends TOP> getClassForIndex(int aIndex)

  Gets the JCas cover class for a given index.

  Parameters:

  aIndex - the index

  Returns:

  the JCas cover class that was assigned the value aIndex during its registration, null if none.
