Method Details

checkInitialization

public void checkInitialization(InitializableProblemHandler problemHandler)
                         throws TikaConfigException

Specified by:

checkInitialization in interface Initializable

Parameters:

problemHandler - if there is a problem and no custom initializableProblemHandler has been configured via Initializable parameters, this is called to respond.

Throws:

TikaConfigException

getSupportedTypes

public Set<MediaType> getSupportedTypes(ParseContext parseContext)

Description copied from interface: Parser

Returns the set of media types supported by this parser when used with the given parse context.

Specified by:

getSupportedTypes in interface Parser

Parameters:

parseContext - parse context

Returns:

immutable set of media types

initialize

public void initialize(Map<String,Param> params)
                throws TikaConfigException

Specified by:

initialize in interface Initializable

Parameters:

params - params to use for initialization

Throws:

TikaConfigException

getAgePredictorClient

public edu.usc.irds.agepredictor.authorage.AgePredicterLocal getAgePredictorClient()
                                                                            throws opennlp.tools.util.InvalidFormatException,
IOException

Throws:

opennlp.tools.util.InvalidFormatException

IOException

setAgePredictorClient

protected static void setAgePredictorClient(edu.usc.irds.agepredictor.authorage.AgePredicterLocal agePredicter)

USED in test cases to mock response of AgeClassifier

parse

public void parse(InputStream inputStream,
 ContentHandler handler,
 Metadata metadata,
 ParseContext context)
           throws IOException

Description copied from interface: Parser

Parses a document stream into a sequence of XHTML SAX events. Fills in related document metadata in the given metadata object.

The given document stream is consumed but not closed by this method. The responsibility to close the stream remains on the caller.

Information about the parsing context can be passed in the context parameter. See the parser implementations for the kinds of context information they expect.

Specified by:

parse in interface Parser

Parameters:

inputStream - the document stream (input)

handler - handler for the XHTML SAX events (output)

metadata - document metadata (input and output)

context - parse context

Throws:

IOException - if the document stream could not be read
