Programmatically check for correctness of Aggregate-TAE

Hi List,

I would like to be able to check the parameter settings of one of my custom 
aggregate TAEs on initialization.
The general idea is that the component engines of the aggregate are configured 
in the aggregates XML descriptor via "overrides". However there are a few 
constraints on the parameter settings that I would like to check when the 
aggregate is initialized.
So far I don't know if and how it is possible to provide an own Java 
implementation for the aggregate TAE. If this is possible, the appropriate place 
would be the aggregates initialize() method, since the configuration is 
accessible there. Can anyone tell me if it is possible to have an implementation 
for an aggregate or not and if so, how? If this isn't possible, where would be 
another good place to do a sanity check on the aggregates parameter settings?

Many thanks in advance,

Christoph

No that's currently not possible... but I agree, it would be nice.

Can a PEAR component be used as a Collection Reader?

Posted by "Chavan, Girish" <ch...@upmc.edu>.
I am trying to use a PEAR component as a collection reader in a CPE descriptor.

I am wondering if I can use the PEAR descriptor as the descriptor for the collectionReader section of the CPE descriptor.

Thanks,
Girish

What about checking the aggregate descriptor settings before you 
initialize it... like:

       File aggDesc = new File("aggregateDescriptor.xml");
       XMLInputSource in = new XMLInputSource(aggDesc);
       AnalysisEngineDescription aeDesc = 
UIMAFramework.getXMLParser().parseAnalysisEngineDescription(in);
       ConfigurationParameterSettings paramSettings = 
aeDesc.getAnalysisEngineMetaData().getConfigurationParameterSettings();

So you can check if the necessary settings are available if not you can 
throw an exception. If all is fine you can instantiate the ae.

Does this help?

What about checking the aggregate descriptor settings before you 
initialize it... like:

       File aggDesc = new File("aggregateDescriptor.xml");
       XMLInputSource in = new XMLInputSource(aggDesc);
       AnalysisEngineDescription aeDesc = 
UIMAFramework.getXMLParser().parseAnalysisEngineDescription(in);
       ConfigurationParameterSettings paramSettings = 
aeDesc.getAnalysisEngineMetaData().getConfigurationParameterSettings();

So you can check if the necessary settings are available if not you can 
throw an exception. If all is fine you can instantiate the ae.
