WebSocketExecute (Function) Executes a global procedure in the context of a client connected to the WebSocket server.
arrClients is array of websocketClient = WebSocketListConnectedClient()
sInformation is string = GetInformation()
FOR EACH Client OF arrClients
WebSocketExecute(Client, SetInformation)
END
Sintaxis
WebSocketExecute(<Client> , <WLanguage procedure> [, <Parameters>])
<Client>: websocketClient variable Name of the websocketClient variable corresponding to the client in which the procedure will be executed. <WLanguage procedure>: Procedure name Name of the global WLanguage procedure to be executed in the context of the client. <Parameters>: List of values enclosed in brackets, separated by commas Parameters of the procedure. This list of parameters has the following format: (<Parameter 1>, ..., <Parameter N>) where: - <Parameter 1> is the first parameter of the procedure.
- ...
- <Parameter N> is the nth parameter of the procedure.
Caution: - Parameters are passed by value.
- Only simple types are allowed: Boolean, integer, ... For example, it is not possible to have a parameter corresponding to an instance of class.
Observaciones Execution contexts The global service of the WebSocket server and the connected clients are executed independently. Each is executed in its own context with: - its own copy of global variables.
- its own database context.
- etc.
Therefore, it is not possible to handle the global context or the context of another client. WebSocketExecute is used to execute the WLanguage procedure passed as parameter in the context of another client. During the execution of the procedure, the global variables will be those of the target client. Asynchronous operating mode Asynchronous operation: the function simply requests execution of the Procedure. The procedure can actually be executed later (after WebSocketExecute has been executed). WebSocketExecute never returns an error (for example, if the client has been disconnected in the meantime). Clasificación Lógica de negocio / UI: Lógica de negocio Componente: wd300awws.dll
