public class FeatureStructureImplC extends Object implements FeatureStructureImpl
Feature structure implementation (for non JCas and JCas) Each FS has - int data - used for boolean, byte, short, int, long, float, double data -- long and double use 2 int slots - may be null if all slots are in JCas cover objects as fields - ref data - used for references to other Java objects, such as -- strings -- other feature structures -- arbitrary Java Objects - may be null if all slots are in JCas cover objects as fields - an id: an incrementing integer, starting at 1, per CAS, of all FSs created for that CAS - a ref to the casView where this FS was created - a ref to the TypeImpl for this class -- can't be static - may be multiple type systems in use

      See http://www.javaworld.com/article/2076332/java-se/how-to-avoid-traps-and-correctly-override-methods-from-java-lang-object.html for suggestions on avoiding bugs in implementing clone Because we have final fields for _intData, _refData, and _id, we can't use clone. Instead, we use the createFS to create the FS of the right type. This will use the generators. Strategy for cloning: Goal is to create an independent instance of some subtype of this class, with all the fields properly copied from this instance. - some fields could be in the _intData and _refData - some fields could be stored as features Subcases to handle: - arrays - these have no features. Note: CasCopier doesn't call this because it needs to do a deep copy This is not used by the framework
      Specified by:
      clone in interface FeatureStructure
      Overrides:
      clone in class Object
      Returns:
      a new Feature Structure as a new instance of the same class, with a new _id field, with its features set to the values of the features in this Feature Structure

      CASRuntimeException - (different from Object.clone()) if an exception occurs
