Programmatically create a CPE

[Fabio Mancinelli <fa...@gmail.com>]

Hi everybody,

I was wondering how I could assemble a CPE from a Java program without
using an XML descriptor.

The idea was to create analysis engines, collection readers and cas
consumers and to assemble them programmatically in a CPE using Java
code.

UIMAFramework.produceCollectionProcessingEngine() requires a
CpeDescription object that apparently can be built only from an XML
file (whose creation is not even supported by the Eclipse UIMA plugin
and, afaiu, it must be created exclusively by using the cpeGui.sh
program).

Any hint?

Thanks,
Fabio

Hi Fabio.

It's in the documentation (it also has nearly the same heading as your subject):
http://incubator.apache.org/uima/downloads/releaseDocs/2.2.2-incubating/docs/html/tutorials_and_users_guides/tutorials_and_users_guides.html#ugr.tug.application.configuring_a_cpe_descriptor_programmatically

Fabio, there is a way to create a CpeDescriptor in your java program.
Use the following:

CpeDescription cd = CpeDescriptorFactory.produceDescriptor();

With the above you get a descriptor with default values. Use the API to change
the descriptor as needed.

Once you have the descriptor configured, you than call:

mCPE = UIMAFramework.produceCollectionProcessingEngine(cpeDesc);
