AnalysisEngineImplBase

public AnalysisEngineImplBase()

Method Details

setMetaData

protected void setMetaData(ResourceMetaData aMetaData)

Description copied from class: Resource_ImplBase

Sets the ResourceMetaData object associated with this Resource. Any previously existing metadata will be replaced.

Resource subclasses should call this method during initialization in order to set the metadata before any calls to Resource_ImplBase.getMetaData() are made.

Overrides:

setMetaData in class Resource_ImplBase

Parameters:

aMetaData - metadata to assign to this Resource

batchProcessComplete

public void batchProcessComplete()
                          throws AnalysisEngineProcessException

Description copied from interface: AnalysisEngine

Notifies this AnalysisEngine that processing of a batch has completed. It is up to the caller to determine the size of a batch. Components (particularly CAS Consumers) inside this Analysis Engine may respond to this event, for example by writing data to the disk.

Specified by:

batchProcessComplete in interface AnalysisEngine

Throws:

AnalysisEngineProcessException - if an exception occurs during processing

collectionProcessComplete

public void collectionProcessComplete()
                               throws AnalysisEngineProcessException

Description copied from interface: AnalysisEngine

Notifies this AnalysisEngine that processing of an entire collection has completed. It is up to the caller to determine when this has occurred. Components (particularly CAS Consumers) inside this Analysis Engine may respond to this event, for example by writing data to the disk.

If this AnalysisEngine is an aggregate, this method will call the collectionProcessComplete method of all components of that aggregate. If the aggregate descriptor declares a fixedFlow or capabilityLanguageFlow, then the components' collectionProcessComplete methods will be called in the order specified by that flow element. Once all components in the flow have been called, any components not declared in the flow will be called, in arbitrary order. If there is no fixedFlow or capabilityLanguageFlow, then all components in the aggregate will be called in arbitrary order.

Specified by:

collectionProcessComplete in interface AnalysisEngine

Throws:

AnalysisEngineProcessException - if an exception occurs during processing

processAndOutputNewCASes

public CasIterator processAndOutputNewCASes(CAS aCAS)
                                     throws AnalysisEngineProcessException

Description copied from interface: AnalysisEngine

Processes a CAS, possibly producing multiple CASes as a result. The application uses the CasIterator interface to step through the output CASes.

If this Analysis Engine does not produce output CASes, then the CasIterator will return no elements. You can check if an AnalysisEngine is capable of producing output CASes by checking the OperationalProperties.getOutputsNewCASes() operational property (getAnalysisEngineMetaData().getOperationalProperties().getOutputsNewCASes()).

Once this method is called, the AnalysisEngine "owns" aCAS until such time as the CasIterator.hasNext() method returns false. That is, the caller should not attempt to modify or access the input CAS until it has read all of the elements from the CasIterator. If the caller wants to abort the processing before having read all of the output CASes, it may call CasIterator.release(), which will stop further processing from occurring, and ownership of aCAS will revert to the caller.

Specified by:

processAndOutputNewCASes in interface AnalysisEngine

Parameters:

aCAS - the CAS to be processed

Returns:

an object for iterating through any output CASes

Throws:

AnalysisEngineProcessException - if a failure occurs during processing

initialize

public boolean initialize(ResourceSpecifier aSpecifier,
 Map<String,Object> aAdditionalParams)
                   throws ResourceInitializationException

Description copied from interface: Resource

Initializes this Resource from a ResourceSpecifier. Applications do not need to call this method. It is called automatically by the ResourceFactory and cannot be called a second time.

Specified by:

initialize in interface AnalysisEngine

Specified by:

initialize in interface Resource

Overrides:

initialize in class Resource_ImplBase

Parameters:

aSpecifier - specifies how to create a resource or locate an existing resource service.

aAdditionalParams - a Map containing additional parameters. May be null if there are no parameters. Each class that implements this interface can decide what additional parameters it supports.

Returns:

true if and only if initialization completed successfully. Returns false if the given ResourceSpecifier is not of an appropriate type for this Resource. If the ResourceSpecifier is of an appropriate type but is invalid or if some other failure occurs, an exception should be thrown.

Throws:

ResourceInitializationException - if a failure occurs during initialization.

See Also:

• multi-thread safe, given that each instance of this class is only called on one thread, once. The critical parts that update shared information (in shared uima context) are inside a synchronize block

finalize

protected void finalize()
                 throws Throwable

Overrides:

finalize in class Object

Throws:

Throwable

getAnalysisEngineMetaData

public AnalysisEngineMetaData getAnalysisEngineMetaData()

Description copied from interface: AnalysisEngine

Gets the metadata that describes this AnalysisEngine. This is just a convenience method that calls Resource.getMetaData() and casts the result to a AnalysisEngineMetaData.

Specified by:

getAnalysisEngineMetaData in interface AnalysisEngine

Returns:

an object containing all metadata for this AnalysisEngine

See Also:

• AnalysisEngine.getAnalysisEngineMetaData()

getProcessingResourceMetaData

public ProcessingResourceMetaData getProcessingResourceMetaData()

Description copied from interface: CasProcessor

Gets the metadata that describes this CasProcesor.

Specified by:

getProcessingResourceMetaData in interface CasProcessor

Returns:

an object containing all metadata for this CasProcessor

See Also:

• CasProcessor.getProcessingResourceMetaData()

newCAS

public CAS newCAS()
           throws ResourceInitializationException

Description copied from interface: AnalysisEngine

Creates a new Common Analysis System appropriate for this Analysis Engine. An application can pre-populate this CAS, then pass it to the AnalysisEngine.process(CAS) method. Then, when the process method returns, the CAS will contain the results of the analysis.

Important: CAS creation is expensive, so if at all possible an application should reuse CASes. When a CAS instance is no longer being used, call its CAS.reset() method, which will remove all prior analysis information, and then reuse that same CAS instance for another call to AnalysisEngine.process(CAS).

Note that the CAS allows multiple subjects of analysis (e.g. documents) and defines a separate "view" for each of them. If your application wants to work with a single subject of analysis, call the method CAS.getCurrentView() and operate on the returned view.

Specified by:

newCAS in interface AnalysisEngine

Returns:

a new CAS appropriate for this AnalysisEngine.

Throws:

ResourceInitializationException - if a CAS could not be created because this AnalysisEngine's CAS metadata (type system, type priorities, or FS indexes) are invalid. Ideally this would be checked at AnalysisEngine initialization time, and it will likely be moved in the future.

See Also:

• AnalysisEngine.newCAS()

newJCas

public JCas newJCas()
             throws ResourceInitializationException

Description copied from interface: AnalysisEngine

Similar to AnalysisEngine.newCAS() but wraps the new CAS objects with the Java-object-based JCas interface.

Note: the JCas that is returned is equivalent to what you would get if you called newCAS().getCurrentView().getJCas(). That is, this method returns a view of the default Sofa, NOT a Base CAS.

Important: CAS creation is expensive, so if at all possible an application should reuse CASes. When a JCas instance is no longer being used, call its JCas.reset() method, which will remove all prior analysis information, and then reuse that same JCas instance for another call to AnalysisEngine.process(JCas).

Specified by:

newJCas in interface AnalysisEngine

Returns:

a new CAS appropriate for this AnalysisEngine.

Throws:

ResourceInitializationException - if a CAS could not be created because this AnalysisEngine's CAS metadata (type system, type priorities, or FS indexes) are invalid. Ideally this would be checked at AnalysisEngine initialization time, and it will likely be moved in the future.

See Also:

• AnalysisEngine.newJCas()

process

public ProcessTrace process(CAS aCAS,
 ResultSpecification aResultSpec)
                     throws ResultNotSupportedException,
AnalysisEngineProcessException

Description copied from interface: AnalysisEngine

Invokes this AnalysisEngine's analysis logic. Prior to calling this method, the caller must ensure that the CAS has been populated with the artifact to be analyzed as well as any inputs required by this AnalysisEngine (as defined by this AnalysisEngine's Capability specification.)

This version of the process method takes a ResultSpecification as an argument. The ResultSpecification is alist of output types and features that the application wants this AnalysisEngine to produce. If you are going to use the same ResultSpecification for multiple calls to process, it is not recommended to use this method. Instead call AnalysisEngine.setResultSpecification(ResultSpecification) once and then call AnalysisEngine.process(CAS) for each CAS that you want to process.

Specified by:

process in interface AnalysisEngine

Parameters:

aCAS - the CAS containing the inputs to the processing. Analysis results will also be written to this CAS.

aResultSpec - a list of outputs that this AnalysisEngine should produce.

Returns:

an object containing information about which AnalysisEngine components have executed and information, such as timing, about that execution.

Throws:

ResultNotSupportedException - if this AnalysisEngine is not capable of producing the results requested in aResultSpec.

AnalysisEngineProcessException - if a failure occurs during processing.

• AnalysisEngine.process(org.apache.uima.cas.CAS, org.apache.uima.analysis_engine.ResultSpecification)

process

public void process(CAS aCAS,
 ResultSpecification aResultSpec,
 ProcessTrace aTrace)
             throws ResultNotSupportedException,
AnalysisEngineProcessException

Description copied from interface: AnalysisEngine

Invokes this AnalysisEngine's analysis logic. Prior to calling this method, the caller must ensure that the CAS has been populated with the artifact to be analyzed as well as any inputs required by this AnalysisEngine (as defined by this AnalysisEngine's Capability specification.)

This version of the process method takes a ResultSpecification as an argument. The ResultSpecification is a list of output types and features that the application wants this AnalysisEngine to produce. If you are going to use the same ResultSpecification for multiple calls to process, it is not recommended to use this method. Instead call AnalysisEngine.setResultSpecification(ResultSpecification) once and then call AnalysisEngine.process(CAS) for each CAS that you want to process.

This version of this method also takes a ProcessTrace object as a parameter. This allows trace events to be written to an existing ProcessTrace rather than a new one.

Specified by:

process in interface AnalysisEngine

Parameters:

aCAS - the CAS containing the inputs to the processing. Analysis results will also be written to this CAS.

aResultSpec - a list of outputs that this AnalysisEngine should produce.

aTrace - the object to which trace events will be recorded

Throws:

ResultNotSupportedException - if this AnalysisEngine is not capable of producing the results requested in aResultSpec.

buildProcessTraceFromMBeanStats

protected ProcessTrace buildProcessTraceFromMBeanStats()

Returns:

a constructed ProcessTrace object that represents the last execution of this AnalysisEngine. This is used so that we can return a ProcessTrace object from each process() call for backwards compatibility with version 1.x.

buildProcessTraceFromMBeanStats

protected void buildProcessTraceFromMBeanStats(ProcessTrace trace)

Modify an existing ProcessTrace object by adding events that represent the last excecution of this AnalysisEngine. This is used so that we can return a ProcessTrace object from each process() call for backwards compatibility with version 1.x.

Parameters:
