All Implemented Interfaces:

AnalysisComponent

public class XmlDetagger
extends CasAnnotator_ImplBase

A multi-sofa annotator that does XML detagging. Reads XML data from the input Sofa (named "xmlDocument"); this data can be stored in the CAS as a string or array, or it can be a URI to a remote file. The XML is parsed using the JVM's default parser, and the plain-text content is written to a new sofa called "plainTextDocument".

Field Summary

static java.lang.String

PARAM_TEXT_TAG Name of optional configuration parameter that contains the name of an XML tag that appears in the input file.

Constructor Summary

XmlDetagger()

Field Detail

PARAM_TEXT_TAG

public static final java.lang.String PARAM_TEXT_TAG

Name of optional configuration parameter that contains the name of an XML tag that appears in the input file. Only text that falls within this XML tag will be considered part of the "document" that it is added to the CAS by this CAS Initializer. If not specified, the entire file will be considered the document.

Method Detail

initialize

public void initialize(UimaContext aContext)
                throws ResourceInitializationException

Description copied from interface: AnalysisComponent

Performs any startup tasks required by this component. The framework calls this method only once, just after the AnalysisComponent has been instantiated.

The framework supplies this AnalysisComponent with a reference to the UimaContext that it will use, for example to access configuration settings or resources. This AnalysisComponent should store a reference to its the UimaContext for later use.

Specified by:

initialize in interface AnalysisComponent

Overrides:

initialize in class AnalysisComponent_ImplBase

Parameters:

aContext - Provides access to services and resources managed by the framework. This includes configuration parameters, logging, and access to external resources.

Throws:

ResourceInitializationException - if this AnalysisComponent cannot initialize successfully.

typeSystemInit

public void typeSystemInit(TypeSystem aTypeSystem)
                    throws AnalysisEngineProcessException

Description copied from class: CasAnnotator_ImplBase

Informs this annotator that the CAS TypeSystem has changed. The Analysis Engine calls this method immediately following the call to AnalysisComponent_ImplBase.initialize(org.apache.uima.UimaContext), and will call it again whenever the CAS TypeSystem changes.

In this method, the Annotator should use the TypeSystem to resolve the names of Type and Features to the actual Type and Feature objects, which can then be used during processing.

Overrides:

typeSystemInit in class CasAnnotator_ImplBase

Throws:

AnalysisEngineProcessException - if the provided type system is missing types or features required by this annotator

process

public void process(CAS aCAS)
             throws AnalysisEngineProcessException

Description copied from class: CasAnnotator_ImplBase

Inputs a CAS to the AnalysisComponent. This method should be overriden by subclasses to perform analysis of the CAS.

Specified by:

process in class CasAnnotator_ImplBase

Parameters:

aCAS - A CAS that this AnalysisComponent should process.

Throws:

AnalysisEngineProcessException - if a problem occurs during processing

getDescription

public static AnalysisEngineDescription getDescription()
                                                throws InvalidXMLException

Parses and returns the descriptor for this Analysis Gnein. The descriptor is stored in the uima-core.jar file and located using the ClassLoader.

Returns:

an object containing all of the information parsed from the descriptor.

Throws:

InvalidXMLException - if the descriptor is invalid or missing

getDescriptorURL

public static java.net.URL getDescriptorURL()
