omni::graph::exec::unstable::ImplementsCastWithoutAcquire

Defined in omni/graph/exec/unstable/IBase.h

template<typename T, typename ...Rest> struct ImplementsCastWithoutAcquire : public T, public Rest 

Helper template for implementing the castWithoutAcquire function for one or more interfaces.

Public Functions

inline void *cast(omni::core::TypeId id) noexcept: See omni::core::IObject::cast.

inline void *castWithoutAcquire(omni::core::TypeId id) noexcept: See omni::graph::exec::unstable::IBase_abi::castWithoutAcquire_abi.

Protected Functions

virtual ~ImplementsCastWithoutAcquire() noexcept = default

inline void *cast_abi(omni::core::TypeId id) noexcept override

Returns a pointer to the interface defined by the given type id if this object implements the type id’s interface.

Objects can support multiple interfaces, even interfaces that are in different inheritance chains.

The returned object will have omni::core::IObject::acquire() called on it before it is returned, meaning it is up to the caller to call omni::core::IObject::release() on the returned pointer.

The returned pointer can be safely reinterpret_cast<> to the type id’s C++ class. For example, “omni.windowing.IWindow” can be cast to omni::windowing::IWindow.

Do not directly use this method, rather use a wrapper function like omni::core::cast() or omni::core::ObjectPtr::as().

Thread Safety: This method is thread safe.

inline void *castWithoutAcquire_abi(omni::core::TypeId id) noexcept override

Casts this object to the type described the the given id.

Returns nullptr if the cast was not successful.

Unlike omni::core::IObject::cast(), this casting method does not call omni::core::IObject::acquire().

Thread Safety: This method is thread safe.
