Atlas_Objects_BaseObjectData: Atlas base object class.

Command to display Atlas_Objects_BaseObjectData manual in Linux: $ man 3 Atlas_Objects_BaseObjectData

NAME

Atlas::Objects::BaseObjectData - Atlas base object class.

SYNOPSIS

Inherited by Atlas::Objects::RootData.

Classes

class const_iterator

class iterator
The iterator first iterates over the contents of m_obj->m_attributes, holding an iterator to the attributes map in m_I.

Detailed Description

Atlas base object class.

This is class is the base from which all classes used to represent high level objects are derived. In this release of Atlas-C++, all classes that inherit from BaseObjectData are designed to be used with SmartPtr and should have the suffix Data on the end of their name. All the subclasses of BaseObjectData included with Atlas-C++ are automatically generated from the Atlas spec at release time. For each subclass a typedef is created of a specialisation of SmartPtr aliasing it to the name of the class without the Data suffix. Thus RootOperationData has an associate type RootOperation which is a typedef for SmartPtr<RootOperationData>. Each class also has an associated integer identifier used to identify classes of its type. The SmartPtr class is designed to store unused instances of the data objects in a memory pool, and reuse instances as they are required. In order to re-use instances without re-constructing all their members, a system of flags is used to mark which members are in use. When an instance is re-used these flags are cleared, indicating that none of the members are in use.

Constructor & Destructor Documentation

Atlas::Objects::BaseObjectData::BaseObjectData (BaseObjectData * defaults)

Construct a new BaseObjectData from a subclass.

Initialises flags to zero, and stores a pointer to the reference object that provides default values for all attributes. Subclasses must pass in a pointer to their class specific reference object.

Member Function Documentation

static BaseObjectData* Atlas::Objects::BaseObjectData::alloc () [inline, static]

Allocate a new instance of this class, using an existing instance if available.

This is the key function for implementing the memory pool for the Atlas::Objects API.

Reimplemented in Atlas::Objects::Entity::AnonymousData, Atlas::Objects::Entity::AdminEntityData, Atlas::Objects::Entity::AccountData, Atlas::Objects::Entity::PlayerData, Atlas::Objects::Entity::AdminData, Atlas::Objects::Entity::GameData, Atlas::Objects::Entity::GameEntityData, Atlas::Objects::Operation::GenericData, Atlas::Objects::Operation::ActionData, Atlas::Objects::Operation::CreateData, Atlas::Objects::Operation::CombineData, Atlas::Objects::Operation::DivideData, Atlas::Objects::Operation::CommunicateData, Atlas::Objects::Operation::TalkData, Atlas::Objects::Operation::DeleteData, Atlas::Objects::Operation::SetData, Atlas::Objects::Operation::AffectData, Atlas::Objects::Operation::MoveData, Atlas::Objects::Operation::WieldData, Atlas::Objects::Operation::GetData, Atlas::Objects::Operation::PerceiveData, Atlas::Objects::Operation::LookData, Atlas::Objects::Operation::ListenData, Atlas::Objects::Operation::SniffData, Atlas::Objects::Operation::TouchData, Atlas::Objects::Operation::LoginData, Atlas::Objects::Operation::LogoutData, Atlas::Objects::Operation::ImaginaryData, Atlas::Objects::Operation::UseData, Atlas::Objects::Operation::InfoData, Atlas::Objects::Operation::PerceptionData, Atlas::Objects::Operation::SightData, Atlas::Objects::Operation::AppearanceData, Atlas::Objects::Operation::DisappearanceData, Atlas::Objects::Operation::SoundData, Atlas::Objects::Operation::SmellData, Atlas::Objects::Operation::FeelData, Atlas::Objects::Operation::ErrorData, Atlas::Objects::RootData, Atlas::Objects::Entity::RootEntityData, and Atlas::Objects::Operation::RootOperationData.

const Atlas::Message::MapType Atlas::Objects::BaseObjectData::asMessage () const

Convert this object to a Object.

This is now legacy, and implemented using addToMessage.

virtual int Atlas::Objects::BaseObjectData::copyAttr (const std::string & name, Atlas::Message::Element & attr) const [virtual]

Retrieve the attribute 'name'.

Return non-zero if it does not exist.

Reimplemented in Atlas::Objects::Entity::AccountData, Atlas::Objects::RootData, Atlas::Objects::Entity::RootEntityData, and Atlas::Objects::Operation::RootOperationData.

virtual void Atlas::Objects::BaseObjectData::free () [pure virtual]

Free an instance of this class, returning it to the memory pool.

This function in combination with alloc() handle the memory pool.

Implemented in Atlas::Objects::Entity::AnonymousData, Atlas::Objects::Entity::AdminEntityData, Atlas::Objects::Entity::AccountData, Atlas::Objects::Entity::PlayerData, Atlas::Objects::Entity::AdminData, Atlas::Objects::Entity::GameData, Atlas::Objects::Entity::GameEntityData, Atlas::Objects::Operation::GenericData, Atlas::Objects::Operation::ActionData, Atlas::Objects::Operation::CreateData, Atlas::Objects::Operation::CombineData, Atlas::Objects::Operation::DivideData, Atlas::Objects::Operation::CommunicateData, Atlas::Objects::Operation::TalkData, Atlas::Objects::Operation::DeleteData, Atlas::Objects::Operation::SetData, Atlas::Objects::Operation::AffectData, Atlas::Objects::Operation::MoveData, Atlas::Objects::Operation::WieldData, Atlas::Objects::Operation::GetData, Atlas::Objects::Operation::PerceiveData, Atlas::Objects::Operation::LookData, Atlas::Objects::Operation::ListenData, Atlas::Objects::Operation::SniffData, Atlas::Objects::Operation::TouchData, Atlas::Objects::Operation::LoginData, Atlas::Objects::Operation::LogoutData, Atlas::Objects::Operation::ImaginaryData, Atlas::Objects::Operation::UseData, Atlas::Objects::Operation::InfoData, Atlas::Objects::Operation::PerceptionData, Atlas::Objects::Operation::SightData, Atlas::Objects::Operation::AppearanceData, Atlas::Objects::Operation::DisappearanceData, Atlas::Objects::Operation::SoundData, Atlas::Objects::Operation::SmellData, Atlas::Objects::Operation::FeelData, Atlas::Objects::Operation::ErrorData, Atlas::Objects::RootData, Atlas::Objects::Entity::RootEntityData, and Atlas::Objects::Operation::RootOperationData.
