Description
User event for capturing and optionally modifying REST results before they are returned.
TDSRESTResultEvent is a user event for capturing and optionally modifying REST results before they are returned.
The JSON value passed in is not wrapped in a result object. If Handled is set to False, then the caller will wrap the value of ResultVal like this: {'result':ResultVal}. Note also that the value passed in might (and probably will) be a JSON Array, containing one or more return values, depending on the method having been invoked. If you change the value held by ResultVal, the new value will be returned.
Sender is the instance that invokes the event.
ResultVal specifies the JSON value that is returned.
Command is the command that is executed.
Handled is set to True if the formatting of the result is required.
