Richard Eckart de Castilho commented on UIMA-4685:
--------------------------------------------------

I think if there is a sensible fallback to be made if a parameter is null, then 
the parameter can as well be optional.
All load methods accept all formats, even if the documentation for the  
load(IS, CAS, TS) says that it only works for form 6. 
I would like to use the method to load all formats and simply optionally supply 
a pre-loaded TS if I have one.
I could do an if/else switch to use a different signature if I don't have a 
pre-loaded TS available, but it somehow seems unnecessary.
... unsure ...

> Create a new CasIOUtils class having common load and save APIs, with optional 
> saving of type system and index definitions, in all the various CAS 
> serialization formats (except JSON).  Implement heuristic discovery for 
> deserialization to support automatic selection of the right kind of 
> deserializer.  Update the headers for binary to support indicating they have 
> the type system included (not used yet).  Update the SerialFormat to support 
> this.  Update the CasEditor and other components to use this new API.
