Method Detail

getSupportedTypes

public 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(InputStream stream,
                  ContentHandler handler,
                  Metadata metadata,
                  ParseContext context)
           throws IOException,
                  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:
IOException - if the document stream could not be read
SAXException - if the SAX events could not be processed
TikaException - if the document could not be parsed
