Public Member Functions
	JSONFile (Context *context)
	Construct.
	~JSONFile () override
	Destruct.
bool	BeginLoad (Deserializer &source) override
	Load resource from stream. May be called from a worker thread. Return true if successful.
bool	Save (Serializer &dest) const override
	Save resource with default indentation (one tab). Return true if successful.
bool	Save (Serializer &dest, const String &indendation) const
	Save resource with user-defined indentation, only the first character (if any) of the string is used and the length of the string defines the character count. Return true if successful.
bool	FromString (const String &source)
	Deserialize from a string. Return true if successful.
String	ToString (const String &indendation="\t") const
	Save to a string.
JSONValue &	GetRoot ()
const JSONValue &	GetRoot () const
	Return root value.
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	EndLoad ()

	Send event to all subscribers.
void	SendEvent (StringHash eventType, VariantMap &eventData)
	Send event with parameters to all subscribers.
VariantMap &	GetEventDataMap () const
	Return a preallocated map for event data. Used for optimization to avoid constant re-allocation of event data maps.
template<typename... Args>
