Detailed Description

Class for handling changing conditions as a function of event number.

Definition at line 22 of file EventDependency.h.

Constructor & Destructor Documentation

EventDependency()

EventDependency ( TObject *  object = 0, bool  owner = true  )

inlineexplicit

Constructor for event depenent conditions.

Parameters

object	the first valid object in the run.
owner	flag that indicates whether the EventDependency takes ownership of the payload objects or not.

Definition at line 30 of file EventDependency.h.

: IntraRunDependency(object, owner) {};

Member Function Documentation

add()

void add	(	unsigned int	event,
		TObject *	object
	)

Add an object to the intra run dependency.

Note that the EventDependency object takes ownership of the added object by default.

Parameters

event	the event number from which on the given conditions object is valid.
object	the object which is valid starting from the given event number.

Definition at line 14 of file EventDependency.cc.

{
  m_objects.Add(object);
  m_eventNumbers.push_back(event);
}

getAnyObject()

TObject * getAnyObject ( ) const

inlineinherited

Get any of the objects.

To be used only by the DBStore for type checking.

Returns

any of the intra-run dependent objects.

Definition at line 53 of file IntraRunDependency.h.

{return m_objects.At(0);};

getBoundaries()

const std::vector< unsigned int > & getBoundaries ( ) const

inlineoverridevirtual

Get a vector with the intra-run boundaries (in this case, event numbers).

In case of no intra-run dependence, the vector is empty. In general for n payloads there are n-1 boundaries.

Implements IntraRunDependency.

Definition at line 58 of file EventDependency.h.

{ return getEventNumbers(); }

getEventNumbers()

const std::vector< unsigned int > & getEventNumbers ( ) const

inline

Get a vector with event number boundaries In case of no intra-run dependence, the vector is empty In general for n payloads there are n-1 boundaries.

Definition at line 45 of file EventDependency.h.

{ return m_eventNumbers; }

getIndex()

int getIndex ( const EventMetaData &  event ) const

overrideprotectedvirtual

Get the index of the object that is valid for the given event.

Parameters

event

meta data of the event for which we want to have the conditions.

Returns

array index of the object valid for the given event.

Implements IntraRunDependency.

Definition at line 21 of file EventDependency.cc.

{
  int result = 0;
  for (unsigned int eventNumber : m_eventNumbers) {
    if (eventNumber > event.getEvent()) return result;
    result++;
  }
  return result;
}

getObject()

TObject * getObject ( const EventMetaData &  event ) const

inlineinherited

Get the conditions object that is valid for the given event.

Parameters

event

meta data of the event for which we want to have the conditions.

Returns

object valid for the given event.

Definition at line 47 of file IntraRunDependency.h.

{return m_objects.At(getIndex(event));};

getObjectByIndex()

TObject * getObjectByIndex ( int  indx ) const

inline

Get the stored object according to indx.

Parameters

indx	index which can have values from 0 to getEventNumbers() - 1

Definition at line 51 of file EventDependency.h.

{return m_objects.At(indx);}

isOwner()

bool isOwner ( ) const

inlineinherited

Flag for ownership.

Returns

true if the IntraRunDependency owns the individual objects.

Definition at line 59 of file IntraRunDependency.h.

{return m_objects.IsOwner();}

Member Data Documentation

m_eventNumbers

std::vector<unsigned int> m_eventNumbers

private

Vector of event number boundaries.

Definition at line 70 of file EventDependency.h.

m_objects

TObjArray m_objects

protectedinherited

Array of intra-run dependent objects.

Definition at line 70 of file IntraRunDependency.h.
