Abstract: A method of providing instructions to computer processing apparatus for improved event handling comprises the following. Instructions for execution on the computer processing apparatus are provided to an event processor generator. These instructions comprise a plurality of functional steps, a set of dependencies between the functional steps, and configuration data. The event processor generator creates instances of the functional steps from the instructions and represents the instances as directed acyclic graphs. The event processor generator identifies a plurality of event types and topologically sort is the directed acyclic graphs to determine a topologically ordered event path for each event type. The event processor generator then provides a revised set of instructions for execution on the computer processing apparatus in which original instructions have been replaced by instructions requiring each event type to be executed according to its topologically ordered event path.
