Expensive Operations

You can show a loading image in the chat window when you know that a response might take longer than usual. This expected delay can be sent as a hint to Leopard.

Instructions

Add an output parameter of command = delay to any output node. Leopard will then show the "thinking" graphic until it next receives a response from Teneo. When the graphic is shown Teneo automatically sends back an empty input to Teneo with a request parameter of command=continue . You can then begin your expensive operation and return the response as per usual.

Remember you can retrieve request parameters in Teneo in Pre-Processing.

Pre-Processing script grabs command parameter and sets it as a global variable

if (engineEnvironment.getParameter("command")) {
	command = engineEnvironment.getParameter("command")
} else {
	command = ""
}
