------------------------------------------------
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();
```
