But how can I specify a order for my custom flow? Is this also possible
or do I have to use configuration parameter settings?
Like this:
<analysisEngineDescription xmlns="http://uima.apache.org/resourceSpecifier";>
<frameworkImplementation>org.apache.uima.java</frameworkImplementation>
<primitive>false</primitive>
<delegateAnalysisEngineSpecifiers>
<delegateAnalysisEngine key="a1">
<import location="Annotator1.xml"/>
</delegateAnalysisEngine>
<delegateAnalysisEngine key="a2">
<import location="Annotator2.xml"/>
</delegateAnalysisEngine>
</delegateAnalysisEngineSpecifiers>
<flowController key="MyFlowController">
<import location="MyFlowController.xml"/>
</flowController>
<analysisEngineMetaData>
<name>Aggregate with custom flow controller</name>
<version>1.0</version>
<vendor>The Apache Software Foundation</vendor>
<flowConstraints>
<fixedFlow>
<node>a1</node>
<node>a2</node>
</fixedFlow>
</flowConstraints>
</analysisEngineMetaData>
</analysisEngineDescription>
Your custom flow controller in its intialization can query the
<flowContraints> and find out that the sequence is supposed to be a1,
a2; and it can act accordingly.
