WebSocket Module
Revision as of 15:27, 4 August 2018 by Johannes Finckh (talk | contribs)
This XQuery Module contains functions for accessing specific WebSocket functions and setting attributes on a WebSocket connection. This module is mainly useful in the context of WebSockets.
Conventions
- The
basex-api
package must be included in the classpath. This is always the case if you use one of the complete distributions (zip, exe, war) of BaseX. - All functions and errors are assigned to the
http://basex.org/modules/websocket
namespace. The module must be imported in the query prolog:
import module namespace websocket = "http://basex.org/modules/websocket"; ...
Functions
