Package io.undertow.server.protocol.http

Class HttpRequestParser

java.lang.Object

io.undertow.server.protocol.http.HttpRequestParser

public abstract class HttpRequestParser
extends Object

The basic HTTP parser. The actual parser is a sub class of this class that is generated as part of the build process by the AbstractParserGenerator annotation processor.

The actual processor is a state machine, that means that for common header, method, protocol values it will return an interned string, rather than creating a new string for each one.

handle

public void handle(ByteBuffer buffer,
                   io.undertow.server.protocol.http.ParseState currentState,
                   HttpServerExchange builder)

handleCachedHeader

protected boolean handleCachedHeader(String existing,
                                     ByteBuffer buffer,
                                     io.undertow.server.protocol.http.ParseState state,
                                     HttpServerExchange builder)

handleAfterVersion

protected void handleAfterVersion(ByteBuffer buffer,
                                  io.undertow.server.protocol.http.ParseState state)

httpStrings

protected static Map<String,HttpString> httpStrings()

This is a bit of hack to enable the parser to get access to the HttpString's that are sorted in the static fields of the relevant classes. This means that in most cases a HttpString comparison will take the fast path == route, as they will be the same object
