Detailed Description

Describes a subscription criteria.

The class provides interfaces to describe a subscription criteria on configuration modifications. A user creates an object of given class and describes criteria using add(const std::string&, const std::string&) and add(const std::string&) methods.

When the subscription criteria is ready, it is necessary to use Configuration::subscribe() method providing subscription criteria and callback. When database information is modified and it matches the criteria, the user's callback with such changes will be invoked.

Member Function Documentation

add() [1/3]

void dunedaq::conffwk::ConfigurationSubscriptionCriteria::add

(

const DalObject &

object

)

Add subscribtion on object changes by object's reference.

Subscribe on changes of object by object's reference. To be used for an object of class generated by genconffwk.

Parameters

object

reference to object

Definition at line 27 of file SubscriptionCriteria.cpp.

{
  add(object.class_name(), object.UID());
}

add() [2/3]

void dunedaq::conffwk::ConfigurationSubscriptionCriteria::add

(

const std::string &

class_name

)

Add subscribtion on class changes.

The notification mechanism is started by the Configuration::subscribe() method. The user callback function passed to this method will be invoked in case of any modification of an object of this class or objects of derived classes.

Parameters

class_name

name of the class

Definition at line 15 of file SubscriptionCriteria.cpp.

{
  m_classes_subscription.insert(class_name);
}

add() [3/3]

void dunedaq::conffwk::ConfigurationSubscriptionCriteria::add	(	const std::string &	class_name,
		const std::string &	object_id )

Add subscribtion on object changes by class name and object id.

Subscribe on changes of object by class name and object identity.

Parameters

class_name	name of the class
object_id	object identity

Definition at line 21 of file SubscriptionCriteria.cpp.

{
  m_objects_subscription[class_name].insert(object_id);
}

get_classes_subscription()

const std::set< std::string > & dunedaq::conffwk::ConfigurationSubscriptionCriteria::get_classes_subscription ( ) const

inline

Return list of names of classes with subsriptions on any changes.

Definition at line 135 of file SubscriptionCriteria.hpp.

{ return m_classes_subscription; }

get_objects_subscription()

const ObjectMap & dunedaq::conffwk::ConfigurationSubscriptionCriteria::get_objects_subscription ( ) const

inline

Return list of objects subsribed on notification in case of changes.

Definition at line 142 of file SubscriptionCriteria.hpp.

{ return m_objects_subscription; }

remove() [1/3]

void dunedaq::conffwk::ConfigurationSubscriptionCriteria::remove

(

const DalObject &

object

)

Remove subscribtion on object changes by reference.

Removes subscription on object changes previously made with add(const std::string&, const std::string&) or add(const DalObject&) methods. To be used for an object of class generated by genconffwk.

Parameters

object

reference to object

Definition at line 53 of file SubscriptionCriteria.cpp.

{
  remove(object.class_name(), object.UID());
}

remove() [2/3]

void dunedaq::conffwk::ConfigurationSubscriptionCriteria::remove

(

const std::string &

class_name

)

Removes subscription on class changes previously made with add(const std::string&) method.

Parameters

class_name

name of the class

Definition at line 33 of file SubscriptionCriteria.cpp.

{
  m_classes_subscription.erase(class_name);
}

remove() [3/3]

void dunedaq::conffwk::ConfigurationSubscriptionCriteria::remove	(	const std::string &	class_name,
		const std::string &	object_id )

Remove subscribtion on object changes by class name and object id.

object_id	object identity

Definition at line 39 of file SubscriptionCriteria.cpp.

{
  ObjectMap::iterator i = m_objects_subscription.find(class_name);
  if (i != m_objects_subscription.end())
    {
      i->second.erase(object_id);
      if (i->second.empty())
        {
          m_objects_subscription.erase(i);
        }
    }
