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
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 org.xml.sax.SAXException
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:
stream - the document stream (input)
handler - handler for the XHTML SAX events (output)
metadata - document metadata (input and output)
context - parse context
Throws:
org.xml.sax.SAXException - if the SAX events could not be processed

parse

public void parse(java.io.InputStream stream,
                  org.xml.sax.ContentHandler handler,
                  Metadata metadata)
           throws java.io.IOException,
                  org.xml.sax.SAXException,
                  TikaException
Deprecated. This method will be removed in Apache Tika 1.0.

Description copied from interface: Parser
The parse() method from Tika 0.4 and earlier. Please use the Parser.parse(InputStream, ContentHandler, Metadata, ParseContext) method instead in new code. Calls to this backwards compatibility method are forwarded to the new parse() method with an empty parse context.

Specified by:
parse in interface Parser
Throws:
java.io.IOException
org.xml.sax.SAXException
TikaException
