Subject [jira] [Created] (UIMA-5807) Support PEARs (ResourceSpecifier) in AnalysisEngineFactory.createEngineDescription
Date Mon, 02 Jul 2018 09:47:00 GMT
Peter Klügl created UIMA-5807:
---------------------------------

             Summary: Support PEARs (ResourceSpecifier) in AnalysisEngineFactory.createEngineDescription
                 Key: UIMA-5807
                 URL: https://issues.apache.org/jira/browse/UIMA-5807
             Project: UIMA
          Issue Type: Improvement
          Components: uimaFIT
            Reporter: Peter Klügl


It is currently a bit cumbersome to use the uimaFIT factories together with UIMA PEARs. A
possible improvement int his direction could be to support the pear wrappers in the AnalysisEngineFactory
methods:

 

{code:java}

public static AnalysisEngineDescription createEngineDescription(
 List<AnalysisEngineDescription> analysisEngineDescriptions, List<String> componentNames,
 TypePriorities typePriorities, SofaMapping[] sofaMappings,
 FlowControllerDescription flowControllerDescription)

{code:java}

 

If another method is added or the given list uses ResourceSpecifier instead of AnalysisEngineDescription
(and some ifs in the loop), then PEARs would be supported.

 

An exemplary implementation could look like:

 

{code:java}

public static AnalysisEngineDescription createEngineDescription(
 List<ResourceSpecifier> resourceSpecifiers, List<String> componentNames,
 TypePriorities typePriorities, SofaMapping[] sofaMappings,
 FlowControllerDescription flowControllerDescription) {

if (componentNames == null) {
 throw new IllegalArgumentException("Parameter [componentNames] cannot be null");
 }

if (resourceSpecifiers == null) {
 throw new IllegalArgumentException("Parameter [analysisEngineDescriptions] cannot be null");
 }

if (resourceSpecifiers.size() != componentNames.size()) {
 throw new IllegalArgumentException("Number of descriptions ["
 + resourceSpecifiers.size() + "]does not match number of component names ["
 + componentNames.size() + "].");
 }

// create the descriptor and set configuration parameters
 AnalysisEngineDescription desc = new AnalysisEngineDescription_impl();
 desc.setFrameworkImplementation(Constants.JAVA_FRAMEWORK_NAME);
 desc.setPrimitive(false);

// if any of the aggregated analysis engines does not allow multiple
 // deployment, then the
 // aggregate engine may also not be multiply deployed
 boolean allowMultipleDeploy = true;
 for (ResourceSpecifier d : resourceSpecifiers) {

// for now only consider AnalysisEngineDescriptions: we implicitly assume that all pears have
allowMultipleDeploy = true
 if (d instanceof AnalysisEngineDescription) {

allowMultipleDeploy &= ((AnalysisEngineDescription) d).getAnalysisEngineMetaData().getOperationalProperties()
 .isMultipleDeploymentAllowed();
 }
 }

desc.getAnalysisEngineMetaData().getOperationalProperties()
 .setMultipleDeploymentAllowed(allowMultipleDeploy);

List<String> flowNames = new ArrayList<String>();

for (int i = 0; i < resourceSpecifiers.size(); i++) {
 ResourceSpecifier aed = resourceSpecifiers.get(i);
 String componentName = componentNames.get(i);
 desc.getDelegateAnalysisEngineSpecifiersWithImports().put(componentName, aed);
 flowNames.add(componentName);
 }

if (flowControllerDescription != null) {
 FlowControllerDeclaration flowControllerDeclaration = new FlowControllerDeclaration_impl();
 flowControllerDeclaration.setSpecifier(flowControllerDescription);
 desc.setFlowControllerDeclaration(flowControllerDeclaration);
 }

FixedFlow fixedFlow = new FixedFlow_impl();
 fixedFlow.setFixedFlow(flowNames.toArray(new String[flowNames.size()]));
 desc.getAnalysisEngineMetaData().setFlowConstraints(fixedFlow);

if (typePriorities != null) {
 desc.getAnalysisEngineMetaData().setTypePriorities(typePriorities);
 }

if (sofaMappings != null) {
 desc.setSofaMappings(sofaMappings);
 }

return desc;
 }

{code:java}
