Detailed Description

Represents database objects.

The class has default constructor, so user can declare instances locally or as a part of an array as he likes. However, the only way to retrieve a valid instance of the class is to call either Configuration::get(const std::string&, const std::string&, ConfigObject&) or Configuration::get(const std::string&, std::vector<ConfigObject>&) method.

The class has a copy constructor and an assignment operator, i.e. instances can be copied, passed by value, etc. All necessary bookkeeping is done transparent to user.

The class has methods to report object's class and identity:

• class_name() return actual class name of the object
• UID() return object's unique identity inside given class

Apart from this there is only one template method get() to retrieve values of object's attributes and relationships.

Constructor & Destructor Documentation

ConfigObject() [1/3]

dunedaq::conffwk::ConfigObject::ConfigObject ( )

The object is invalid until it is initialized by the Configuration::get(const std::string&, const std::string&, ConfigObject&) or Configuration::get(const std::string&, std::vector<ConfigObject>&) method.

Definition at line 20 of file ConfigObject.cpp.

  : m_impl(nullptr)

class_name()

const std::string & dunedaq::conffwk::ConfigObject::class_name ( ) const

Return object's class name.

It corresponds to the actual name of the class from the database implementation.

The pair UID (see UID() method) and class name allows to identify object inside database.

full_name()

const std::string dunedaq::conffwk::ConfigObject::full_name ( ) const

{ return UID() + '@' + class_name(); }

get()

template<class T>

void dunedaq::conffwk::ConfigObject::get ( const std::string & name, T & value )

referenced_by()

void dunedaq::conffwk::ConfigObject::referenced_by ( std::vector< ConfigObject > & value, const std::string & relationship_name = "*", bool check_composite_only = true, unsigned long rlevel = 0, const std::vector< std::string > * rclasses = nullptr ) const

inline

Get objects which have references to given object.

The method returns objects, which have references on given object via explicitly provided relationship name. If the relationship name is set to "*", then the method takes into account all relationships of all objects. The method is efficient only for composite relationships (i.e. when a parent has composite reference on this object). For generic relationships the method performs full scan of all database objects, so at large scale this method should not be applied to every object.

Parameters

value	returned objects
relationship_name	name of relationship (if "*", then return objects referencing via ANY relationship)
check_composite_only	only returned composite parent objects
rlevel	optional references level to optimize performance (defines how many objects referenced by given object have also to be read to the implementation cache)
rclasses	optional array of class names to optimize performance (defines which referenced objects have to be read to the implementation cache)

Exceptions

dunedaq::conffwk::Generic

in case of an error

UID()

const std::string & dunedaq::conffwk::ConfigObject::UID ( ) const

inlinenoexcept

Return object identity.

The identity corresponds to the unique identity of object within it's class. It is taken from database implementation. For named objects it can be a meaningful string.

The pair UID and class name (see class_name() method) allows to identify object inside database.
