Abstract:
1. A method for modifying a graph-based representation of an executable data processing application, the graph-based representation including a graph having vertices representing components and links between components indicating flows of data between such components, at least some of the components comprising data processing components having parameters, including: programmatically retrieving definitions of runtime parameters for the graph at runtime execution of the graph, the runtime parameters being defined as determinable at runtime execution of the graph; determining whether a value for each of the runtime parameters is to be provided by user input; determining whether a value for each of the runtime parameters is to be externally supplied programmatically; displaying a prompt to a user for receiving user input for every runtime parameter so determined to be provided by user input; retrieving any externally supplied value for every runtime parameter determined to be externally supplied programmatically; determining parameter values for the runtime parameters based on the user input to such prompt or such externally supplied value or a default value; modifying the graph-based representation of the data processing application using the determined parameter values for the runtime parameters; and executing the data processing application represented by the modified graph-based representation to process at least one flow of data received by at least one data processing component.
