omni::graph::exec::unstable::ScheduleFunction

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

template<typename Fn>
class ScheduleFunction : public omni::graph::exec::unstable::Implements<IScheduleFunction>

Core ScheduleFunction implementation for omni::graph::exec::unstable::IScheduleFunction.

See omni::graph::exec::unstable::IScheduleFunction for documentation on this type.

Public Functions

inline void acquire() noexcept

Increments the object’s reference count.

Objects may have multiple reference counts (e.g. one per interface implemented). As such, it is important that you call omni::core::IObject::release() on the same pointer from which you called omni::core::IObject::acquire().

Do not directly use this method, rather use omni::core::ObjectPtr, which will manage calling omni::core::IObject::acquire() and omni::core::IObject::release() for you.

Thread Safety

This method is thread safe.

inline void release() noexcept

Decrements the objects reference count.

Most implementations will destroy the object if the reference count reaches 0 (though this is not a requirement).

Objects may have multiple reference counts (e.g. one per interface implemented). As such, it is important that you call omni::core::IObject::release() on the same pointer from which you called omni::core::IObject::acquire().

Do not directly use this method, rather use omni::core::ObjectPtr, which will manage calling omni::core::IObject::acquire() and omni::core::IObject::release() for you.

Thread Safety

This method is thread safe.

inline uint32_t getUseCount() noexcept

Returns the number of different instances (this included) referencing the current object.

Thread Safety

This method is thread safe.

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

inline Status invoke_abi() noexcept override

inline void acquire_abi() noexcept override

Increments the object’s reference count.

Thread Safety

inline void release_abi() noexcept override

Decrements the objects reference count.

Objects may have multiple reference counts (e.g. one per interface implemented). As such, it is important that you call omni::core::IObject::release() on the same pointer from which you called omni::core::IObject::acquire().

Thread Safety

This method is thread safe.

inline uint32_t getUseCount_abi() noexcept override

Returns the number of different instances (this included) referencing the current object.

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.

Protected Attributes

std::atomic<uint32_t> m_refCount
