const ProfilerBlockGetRootBlock ()
 Return the root profiling block.
 
- Public Member Functions inherited from Urho3D::Object
 Object (Context *context)
 Construct.
 
 ~Object () override
 Destruct. Clean up self from event sender & receiver structures.
 
virtual StringHash GetType () const =0
 
virtual const StringGetTypeName () const =0
 
virtual const TypeInfoGetTypeInfo () const =0
 Return type info.
 
virtual void OnEvent (Object *sender, StringHash eventType, VariantMap &eventData)
 Handle event.
 
bool IsInstanceOf (StringHash type) const
 Check current instance is type of specified type.
 
bool IsInstanceOf (const TypeInfo *typeInfo) const
 Check current instance is type of specified type.
 
template<typename T >
bool IsInstanceOf () const
 Check current instance is type of specified class.
 
template<typename T >
T * Cast ()
 Cast the object to specified most derived class.
 
template<typename T >
const T * Cast () const
 Cast the object to specified most derived class.
 
void SubscribeToEvent (StringHash eventType, EventHandler *handler)
 Subscribe to an event that can be sent by any sender.
 
void SubscribeToEvent (Object *sender, StringHash eventType, EventHandler *handler)
 Subscribe to a specific sender's event.
 
void SubscribeToEvent (StringHash eventType, const std::function< void(StringHash, VariantMap &)> &function, void *userData=nullptr)
 Subscribe to an event that can be sent by any sender.
 
void SubscribeToEvent (Object *sender, StringHash eventType, const std::function< void(StringHash, VariantMap &)> &function, void *userData=nullptr)
 Subscribe to a specific sender's event.

void UnsubscribeFromAllEvents ()
 Unsubscribe from all events.
 
void UnsubscribeFromAllEventsExcept (const PODVector< StringHash > &exceptions, bool onlyUserData)
 Unsubscribe from all events except those listed, and optionally only those with userdata (script registered events).
 
void SendEvent (StringHash eventType)
 Send event to all subscribers.
 
void SendEvent (StringHash eventType, VariantMap &eventData)
 Send event with parameters to all subscribers.
 
VariantMapGetEventDataMap () const
 Return a preallocated map for event data. Used for optimization to avoid constant re-allocation of event data maps.
 
template<typename... Args>

EventHandlerGetEventHandler () const
 Return active event handler. Null outside event handling.
 
bool HasSubscribedToEvent (StringHash eventType) const
 Return whether has subscribed to an event without specific sender.
 
bool HasSubscribedToEvent (Object *sender, StringHash eventType) const
 Return whether has subscribed to a specific sender's event.
 
bool HasEventHandlers () const
 Return whether has subscribed to any event.
 
template<class T >
T * GetSubsystem () const

- Public Member Functions inherited from Urho3D::RefCounted
 RefCounted ()
 Construct. Allocate the reference count structure and set an initial self weak reference.
 
virtual ~RefCounted ()

int WeakRefs () const
 
RefCountRefCountPtr ()
 Return pointer to the reference count structure.
 

Static Public Member Functions

static void SetActive (bool newActive)
