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)

Throws:

BadRequestException

handleCachedHeader

                                     ByteBuffer buffer,
                                     io.undertow.server.protocol.http.ParseState state,

handleAfterVersion

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

Throws:

BadRequestException

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

Returns:
