Class Parser

java.lang.Object

org.eclipse.jetty.fcgi.parser.Parser

Direct Known Subclasses:

ClientParser, ServerParser

public abstract class Parser
extends Object

The FastCGI protocol exchanges frames.

struct frame {
    ubyte version;
    ubyte type;
    ushort requestId;
    ushort contentLength;
    ubyte paddingLength;
    ubyte reserved;
    ubyte[] content;
    ubyte[] padding;
}

Depending on the type, the content may have a different format, so there are specialized content parsers.
