  +--antsim.impl.GenericRequestGenerator

All Implemented Interfaces:

Clearable, RequestGenerator

public class GenericRequestGenerator

extends Object

implements RequestGenerator

This class implements a generic request generator. To create a request, the generator selects randomly (with uniform probability) a resource from a resource set, creates a generic request for that resource and assign it randomly to one of the nests included in the peernet. The number of requests that are generated for each invocation of method generateRequests can be configured through the NumberOfRequests parameter.
