Hi Christoph,
yes, the specifier actually should have been named description. I
followed your instructions and they worked for me. Thank you very much!
I'm using a Properties object and of course I can only obtain String
objects from it. settings.setParameterValue(name, value) requires the
type of value to match the type specified in the descriptor. Here's a
little trick that does it:
private Object autoConvertParameter(Object originalParameter, String
value) {
if ( originalParameter instanceof Boolean) {
return Boolean.parseBoolean(value);
}
if ( originalParameter instanceof Integer) {
return Integer.parseInt(value);
}
if ( originalParameter instanceof Float) {
return Float.parseFloat(value);
}
// fallback: return as string
return new String(value);
}
Object genericTypeValue =
autoConvertParameter(settings.getParameterValue(key), value);
settings.setParameterValue(key, genericTypeValue);
If there is a more elegant solution, let me know. The hack above will of
course fail in certain situations (wrong config values), but at least it
won't run into producing garbage.
Best,
Niels

Hi Niels,
you might want to try to modify what you call the 'specifier' (I guess
its a AnalysisEngineDescription) before you call
UIMAFramework.produceAnalysisEngine(specifier)
I used this in Unit tests during setup, something like this:
--------
URL descResource =
LexProcessingWriterTest.class.getClassLoader().getResource(
"MyDescriptor.xml");
AnalysisEngineDescription) aeDescription =
UIMAFramework.getXMLParser().parseAnalysisEngineDescription(
new XMLInputSource(descResource));
ConfigurationParameterSettings settings =
aeDescription.getAnalysisEngineMetaData().getConfigurationParameterSettings();
------------
Now that you have the settings you can set/overwrite values like:
settings.setParameterValue(name, value);
At the end when you produce the analysis engine with the modified values
there shouldn't be any problem:
myAE = UIMAFramework.produceAnalysisEngine(aeDescription);
Hope that helps,
Christoph

Hello everybody,
I'm new to this mailing list, however I'm not so new to UIMA.
Here's my issue: I am trying to set the parameters of an Aggregate AE
from within my Java program.
I tried the following the solution I found here:
http://www.mail-archive.com/[email protected]/msg01241.html#
which is basically to produce an annotator and then to configure it using
annotator.setConfigParameterValue("ParamName","NewValue");
This does not work for me as
annotator = UIMAFramework.produceAnalysisEngine(specifier);
which I'm using before to produce the Aggregate initializes its AEs
with the default parameters. These default parameters are of course
not suitable for use in the given scenario, causing the initialization
to fail before I correct the configuration.
I tried to use
produceAnalysisEngine(ResourceSpecifier aSpecifier, Map
aAdditionalParams)
instead but the additional parameters don't do the job. Perhaps I
misunderstood the purpose of these additional parameters in the function.
How can I specify the parameteres of an (Aggregate) AE before it is
initialized?
Thank you very much for your assistance.
Best,
Niels Ott
