const VariantGetMetadata (const String &name) const
 Return metadata variable.
 
bool HasMetadata () const
 Return whether the resource has metadata.
 
- Public Member Functions inherited from Urho3D::Resource
 Resource (Context *context)
 Construct.
 
bool Load (Deserializer &source)
 Load resource synchronously. Call both BeginLoad() & EndLoad() and return true if both succeeded.
 
virtual bool BeginLoad (Deserializer &source)
 Load resource from stream. May be called from a worker thread. Return true if successful.
 
virtual bool EndLoad ()
 Finish resource loading. Always called from the main thread. Return true if successful.
 
virtual bool Save (Serializer &dest) const
 Save resource. Return true if successful.
 
bool LoadFile (const String &fileName)
 Load resource from file.
 
virtual bool SaveFile (const String &fileName) const
 Save resource to file.
 
void SetName (const String &name)
 Set name.
 
void SetMemoryUse (unsigned size)
 Set memory use in bytes, possibly approximate.
 
void ResetUseTimer ()
 Reset last used timer.
 
void SetAsyncLoadState (AsyncLoadState newState)
 Set the asynchronous loading state. Called by ResourceCache. Resources in the middle of asynchronous loading are not normally returned to user.
 
const StringGetName () const
 Return name.
 
StringHash GetNameHash () const
 Return name hash.
 
unsigned GetMemoryUse () const
 Return memory use in bytes, possibly approximate.
 
unsigned GetUseTimer ()
 Return time since last use in milliseconds. If referred to elsewhere than in the resource cache, returns always zero.
 
AsyncLoadState GetAsyncLoadState () const
 Return the asynchronous loading state.
 
- Public Member Functions inherited from Urho3D::Object
 Object (Context *context)
 Construct.
 
virtual ~Object ()

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.
 
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)

 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.
 
ContextGetContext () const
 Return execution context.
 
const VariantGetGlobalVar (StringHash key) const
 Return global variable based on key.
 
const VariantMapGetGlobalVars () const
 Return all global variables.
 
void SetGlobalVar (StringHash key, const Variant &value)
 Set global variable with the respective key and value.
 
ObjectGetSubsystem (StringHash type) const

bool HasEventHandlers () const
 Return whether has subscribed to any event.
 
template<class T >
T * GetSubsystem () const
 Template version of returning a subsystem.
 
const StringGetCategory () const
 Return object category. Categories are (optionally) registered along with the object factory. Return an empty string if the object category is not registered.
 
- Public Member Functions inherited from Urho3D::RefCounted
