Class CryptoParser

  • All Implemented Interfaces:
    java.io.Serializable, Parser
    public abstract class CryptoParser

                  org.xml.sax.ContentHandler handler,
                  Metadata metadata,

        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
