Method Detail

getSupportedTypes

public java.util.Set<MediaType> getSupportedTypes(ParseContext context)

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

Overrides:

getSupportedTypes in class DelegatingParser

Parameters:

context - parse context

Returns:

immutable set of media types

parse

public void parse(java.io.InputStream stream,
                  org.xml.sax.ContentHandler handler,
                  Metadata metadata,
                  ParseContext context)
           throws java.io.IOException,
                  org.xml.sax.SAXException,
                  TikaException

Description copied from class: DelegatingParser

Looks up the delegate parser from the parsing context and delegates the parse operation to it. If a delegate parser is not found, then an empty XHTML document is returned.

Subclasses should override this method to parse the top level structure of the given document stream. Parsed sub-streams can be passed to this base class method to be parsed by the configured delegate parser.

Specified by:

parse in interface Parser

Overrides:

parse in class DelegatingParser

Parameters:

stream - the document stream (input)

handler - handler for the XHTML SAX events (output)

metadata - document metadata (input and output)

context - parse context

Throws:

java.io.IOException - if the document stream could not be read

org.xml.sax.SAXException - if the SAX events could not be processed

TikaException - if the document could not be parsed
