class Generated<omni::graph::exec::unstable::IPassFactory_abi> : public omni::graph::exec::unstable::IPassFactory_abi

Factory interface for creating omni::graph::exec::unstable::IPass objects.

Usually used in conjunction with omni::graph::exec::unstable::IPassRegistry.

See omni::graph::exec::unstable::createPassFactory() to generate one of these objects from an invocable object (e.g. std::function).

See Pass Concepts for an in-depth guide on how passes are used during graph construction.

See Pass Registration for more information about pass registration.

See Passes for more pass related functionality.

Public Functions

inline omni::core::ObjectPtr<omni::graph::exec::unstable::IPass> createPass(

omni::core::ObjectParam<omni::graph::exec::unstable::IGraphBuilder> builder,

) noexcept

Creates and returns a pass.

The returned pointer is always valid.

builder is the graph builder the new pass should use. builder must not be nullptr.

The returned omni::graph::exec::unstable::IPass will have omni::core::IObject::acquire() called on it.

Thread Safety

This method is thread safe and expected to be called concurrently by omni::graph::exec::unstable::IPassPipeline.

inline void *castWithoutAcquire(omni::core::TypeId id) noexcept

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.

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

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 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.
