Interface SimulationInfrastructure

All Known Implementing Classes:

DefaultSimulationInfrastructure

public interface SimulationInfrastructure

Represents a simulation infrastructure in which system load as specified by FakeLoad objects is simulated.

A simulation infrastructure is built up of different tasks. Each task serves a specific simulation purpose. There should be tasks responsible for CPU load simulation, for memory simulation, etc. A SimulationInfrastructure provides functionality for adjusting system loads via increase and decrease methods.

Class DefaultSimulationInfrastructure provides a default implementation of an infrastructure.

Method Summary

Modifier and Type	Method and Description
void	decreaseSystemLoadBy(FakeLoad load) Decreases the system load simulated by the simulation infrastructure by the specified FakeLoad
void	increaseSystemLoadBy(FakeLoad load) Increases the system load simulated by the simulation infrastructure by the specified FakeLoad instance

Method Detail

increaseSystemLoadBy

void increaseSystemLoadBy(FakeLoad load)
                   throws MaximumLoadExceededException

Increases the system load simulated by the simulation infrastructure by the specified FakeLoad instance

Parameters:

load - the load by which the overall system load is increased

Throws:

MaximumLoadExceededException - in case the specified increase of the system load would exceed the allowed maximum load of the system

decreaseSystemLoadBy

void decreaseSystemLoadBy(FakeLoad load)

Decreases the system load simulated by the simulation infrastructure by the specified FakeLoad

Parameters:

load - the load by which the overall system load is decreased

Throws:

RuntimeException - in case the specified decrease would cause an illegal (e.g. negative) system load
