Constructor Detail

AbstractSimulatingDriver

protected AbstractSimulatingDriver(Map<String,String> info)

Initializes a time-keeper object as a storage space for non-simulated command execution times.

Parameters:

info -

Method Detail

addCommandTime

public void addCommandTime(Object command,
                           double time)

getCommandTimeAverage

public double getCommandTimeAverage(Object command)

getCommandTimeSigma

public double getCommandTimeSigma(Object command)

getCommandTimeRandomSample

public double getCommandTimeRandomSample(Object command)

exit

public void exit()

Specified by:

exit in interface ExitCleaning

startSimulate

public boolean startSimulate()

A driver can be put into simulation mode only before it has been opened, otherwise an illegal state exception is thrown.

Specified by:

startSimulate in interface Simulating

stopSimulate

public boolean stopSimulate()

Stops the simulation. If we now continue with program execution and open the driver, it is physically opened. Once opened, it cannot be put into simulation mode again.

Specified by:

stopSimulate in interface Simulating

accelerate

public boolean accelerate(double by)
                   throws UnsupportedOperationException

Accelerates the time flow by the stated factor. For an beckhoff polling server this means that the variable monitor is sped up (i.e. updating its fake-cache faster) and also the communication delay is shortened.

Specified by:

accelerate in interface Simulating

Throws:

UnsupportedOperationException

isSimulate

protected boolean isSimulate()

getSimulationStart

protected long getSimulationStart()

simulateSince

protected long simulateSince()

getAcceleration

protected double getAcceleration()

restore

public boolean restore()

We restore our old value by reading the last date and target count from a serialization file.

Specified by:

restore in interface Preserving

preserve

public boolean preserve()

On exit, we save our current state if the serialize property is set. First the date, then the targetnumber is writtn.

Specified by:

preserve in interface Preserving
