I suspect this is some mostly-internal type that is there for any common things among the various types of lists (it's a common supertype of lists of floats, of ints, of fsRefs, etc.).
It is not something that can be directly instantiated. That's why there's no JCas type for it. There's a similar type, ArrayBase, for Arrays... My guess is that they're structural placeholders at this time - I don't think there's any common behavior, etc., assigned to them (but I could be wrong...) -Marshall On 7/24/2013 11:10 AM, Richard Eckart de Castilho wrote: > Hi, > > I noticed there is a type "ListBase" listed amongst the possible supertypes > in the CDE. > I found a reference to this type in CAS.TYPE_NAME_LIST_BASE but nowhere else. > > There also appears to be a CAS.TYPE_NAME_ARRAY_BASE, but "ArrayBase" is not > offered > as a supertype in the CDE. > > There appear to be no JCas classes for these types. > > What are these types used for? > > Cheers, > > -- Richard
