Typedefs

using instead = abstract_component_base<Component>

template<typename Component = void>
class abstract_component_base

template<typename Component, typename Derived = void>
class abstract_managed_component_base

template<typename Component>
class component

#include <components_base_fwd.hpp>

The component class wraps around a given component type, adding additional type aliases and constructors. It inherits from the specified component type.

template<typename Component = void>
class component_base

#include <components_base_fwd.hpp>

component_base serves as a base class for components. It provides common functionality needed by components, such as address and ID retrieval. The template parameter Component specifies the derived component type.

template<typename Component>
class fixed_component

template<typename Component>
class fixed_component_base

template<typename Component, typename Derived>
class managed_component

#include <managed_component_base.hpp>

The managed_component template is used as an indirection layer for components allowing to gracefully handle the access to non-existing components.

Additionally, it provides memory management capabilities for the wrapping instances, and it integrates the memory management with the AGAS service. Every instance of a managed_component gets assigned a global id. The provided memory management allocates the managed_component instances from a special heap, ensuring fast allocation and avoids a full network round trip to the AGAS service for each of the allocated instances.

Template Parameters

• Component – Component type

• Derived – Most derived component type

template<typename Component, typename Wrapper, typename CtorPolicy, typename DtorPolicy>
