public class Driver

extends EventAnalyzer

implements Processor

A driver is a steering routine which can call a number of processors It also allows controlling the debug level of the processors being called and handles coordination of random numbers between Monte Carlo processors. Driver also implements Processor, so Drivers can be nested as Processors within other Drivers. When used as a nested driver all parameters such as histogramLevel and debugLevel are inherited from the parent driver.

Method Detail

add

public void add(Processor p)

Add a Processor to this Driver

Parameters:

p - The Processor to be added

remove

public void remove(Processor p)

Removes a Processor from this Driver

Parameters:

p - The Processor to be removed

contains

public boolean contains(Processor p)

Tests to see if a given Processor is already added to this Driver

Parameters:

p - Processor to be checked

processEvent

public void processEvent(EventData data)

Overrides:

processEvent in class EventAnalyzer

setDetector

public void setDetector(Detector det)

Description copied from interface: Processor

Called by the driver when a new detector geometry is set. This will always be called before the first call to process(), and subsequently each time the Detector geometry changes.

Specified by:

setDetector in interface Processor

beforeFirstEvent

public void beforeFirstEvent()

Overrides:

beforeFirstEvent in class EventHandler

afterLastEvent

public void afterLastEvent()

Overrides:

afterLastEvent in class EventHandler

getSeed

public long getSeed()

setSeed

public void setSeed(long newSeed)

getDebugLevel

public int getDebugLevel()

setDebugLevel

public void setDebugLevel(int level)

getHistogramLevel

public int getHistogramLevel()

setHistogramLevel

public void setHistogramLevel(int level)

process

public void process(LCDEvent event)

Description copied from interface: Processor

Called by the driver when this processor should process an event. If the processor produces new output it should add it to the event.

Specified by:

process in interface Processor

Following copied from interface: hep.lcd.util.driver.Processor

Parameters:

event - The event to process

start

public void start()

Description copied from interface: Processor

Called at the beginning of processing

Specified by:

start in interface Processor

stop

public void stop()

Description copied from interface: Processor

Called at the end of processing

Specified by:

stop in interface Processor

setContext

public void setContext(ProcessorContext value)

Description copied from interface: Processor

Called by the Driver when this processor is added to the Driver

Specified by:

setContext in interface Processor

Following copied from interface: hep.lcd.util.driver.Processor

Parameters:

context - the new ProcessorContext

clearContext

public void clearContext()

Description copied from interface: Processor

Called by the Driver when this processor is removed from the Driver

Specified by:

clearContext in interface Processor

getName

public String getName()

Description copied from interface: Processor

Called by the Driver to get the name of this processor

Specified by:

getName in interface Processor

Following copied from interface: hep.lcd.util.driver.Processor

Returns:

The name of the processor
