Constant Value
apama.analyticsbuilder.blocks.ConstantValue
Outputs a value, either when the Trigger input port receives a signal or at startup.
The Trigger input port can be used to delay the output until a trigger input is received. If the Trigger input port is not connected, then the block outputs a value when the model is activated, which may trigger further processing.
The Value parameter can be treated as either a string, or as a JSON value. For JSON string, number or boolean, then that will be the type of the output. For JSON objects, the output will be a pulse with the properties from the object. JSON arrays are only permitted within an object.
