             Summary: Better alternative for CasCreationUtils
                 Key: UIMA-6382
                 URL: https://issues.apache.org/jira/browse/UIMA-6382
             Project: UIMA
          Issue Type: New Feature
          Components: Core Java Framework
            Reporter: Richard Eckart de Castilho


The {{CasCreationUtils}} class is the way of creating new CAS instances, but its signatures are becoming a bit unwieldy. E.g. we have a {{CasCreationUtils.createCas()}} to create a CAS without any type system definition and we have a {{CasCreationUtils.createCas(tsd, null, null, null)}} to create one with a type system definition and nothing really in between.

In would propose investigating a builder-like approach where we could write something like:

```
CAS cas = CAS.builder().withTypeSystem(tsd).build();

CAS cas = CAS.builder()
   .withDefinition(CasDefinition)
   .withTypeSystem(tsd)
   .withTypePriorities(...)
   .withFsIndexes(...)
   .addAnalysisEngineDescription(...) // can be called multiple times
   .addMetaDataObject(...) // can be called multiple times
   .withResourceManager(...)
   .withProperties(...)
   .withProperty(...)
   .build();
```
