template<>
class Generated<omni::log::ILogChannelUpdateConsumer_abi> : public omni::log::ILogChannelUpdateConsumer_abi

Consumes (listens for) state change to one or more omni::log::ILog objects.

Add this object to an omni::log::ILog via omni::log::ILog::addChannelUpdateConsumer().

Subclassed by omni::log::ILogChannelUpdateConsumer

Public Functions

inline void onChannelUpdate(omni::core::ObjectParam<omni::log::ILog> log, omni::core::ObjectParam<omni::str::IReadOnlyCString> name, omni::log::ChannelUpdateReason reason) noexcept

Called when an attached omni::log::ILog’s state changes.

Accessing the given omni::log::ILog from this method is safe.

If name is nullptr, the change happened to the global log (i.e. not to a specific channel).

Updates may come out-of-order and may be spurious.

Thread Safety

This method must be thread safe as the attached ILogs may send messages to this object in parallel.

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().
