Package org.eclipse.jetty.websocket.api.util

Class QuoteUtil

  • @Deprecated(since="2021-05-27")
public class QuoteUtil
extends java.lang.Object
    Deprecated.
    The Eclipse Jetty and Apache Felix Http Jetty packages are no longer supported.
    Provide some consistent Http header value and Extension configuration parameter quoting support.

    While QuotedStringTokenizer exists in jetty-util, and works great with http header values, using it in websocket-api is undesired.

    • Using QuotedStringTokenizer would introduce a dependency to jetty-util that would need to be exposed via the WebAppContext classloader
    • ABNF defined extension parameter parsing requirements of RFC-6455 (WebSocket) ABNF, is slightly different than the ABNF parsing defined in RFC-2616 (HTTP/1.1).
    • Future HTTPbis ABNF changes for parsing will impact QuotedStringTokenizer
    It was decided to keep this implementation separate for the above reasons.
