The call

>> AnalysisEngineFactory.createPrimitiveDescription(TestEngine.class);


Scans the classpath for all type system descriptors, loads them and
merges them. How this is done and how types can be made detectable
is documented here:

  https://code.google.com/p/uimafit/wiki/TypeDescriptorDetection

Btw. I've been playing with the thought of adding support for =
result-specs
to uimaFIT. I'm thinking of something that starts with all the types=20
declared by the component, which then allows easy removal of undesired
types (which has so far been my most prominent use-case) without having
to explicitly specify all types that should be in the result.

Cheers,
