    `class` | `FeatureStructureImplC` 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
