Public Member Functions
	Log (Context *context)
	Construct.
virtual	~Log ()
	Destruct. Close the log file if open.
void	Open (const String &fileName)
	Open the log file.
void	Close ()
	Close the log file.
void	SetLevel (int level)
	Set logging level.
void	SetTimeStamp (bool enable)
	Set whether to timestamp log messages.
void	SetQuiet (bool quiet)
	Set quiet mode ie. only print error entries to standard error stream (which is normally redirected to console also). Output to log file is not affected by this mode.
int	GetLevel () const
	Return logging level.
bool	GetTimeStamp () const
	Return whether log messages are timestamped.
String	GetLastMessage () const
	Return last log message.
bool	IsQuiet () const
	Return whether log is in quiet mode (only errors printed to standard error stream).
Public Member Functions inherited from Urho3D::Object
	Object (Context *context)
	Construct.
virtual	~Object ()
	Destruct. Clean up self from event sender & receiver structures.
virtual StringHash	GetType () const =0
	Return type hash.
virtual const String &	GetTypeName () const =0
	Return type name.
virtual const TypeInfo *	GetTypeInfo () 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.
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	UnsubscribeFromEvent (StringHash eventType)
	Unsubscribe from an event.
void	UnsubscribeFromEvent (Object *sender, StringHash eventType)
	Unsubscribe from a specific sender's event.
void	UnsubscribeFromEvents (Object *sender)
	Unsubscribe from a specific sender's events.
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.
VariantMap &	GetEventDataMap () const
	Return a preallocated map for event data. Used for optimization to avoid constant re-allocation of event data maps.
Context *	GetContext () const
	Return execution context.
const Variant &	GetGlobalVar (StringHash key) const
	Return global variable based on key.
const VariantMap &	GetGlobalVars () const
	Return all global variables.
void	SetGlobalVar (StringHash key, const Variant &value)
	Set global variable with the respective key and value.
Object *	GetSubsystem (StringHash type) const
	Return subsystem by type.
Object *	GetEventSender () const
	Return active event sender. Null outside event handling.
EventHandler *	GetEventHandler () 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
	Template version of returning a subsystem.
const String &	GetCategory () 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
	RefCounted ()
	Construct. Allocate the reference count structure and set an initial self weak reference.
virtual	~RefCounted ()
	Destruct. Mark as expired and also delete the reference count structure if no outside weak references exist.
void	AddRef ()
	Increment reference count. Can also be called outside of a SharedPtr for traditional reference counting.
void	ReleaseRef ()
	Decrement reference count and delete self if no more references. Can also be called outside of a SharedPtr for traditional reference counting.
int	Refs () const
	Return reference count.
int	WeakRefs () const
	Return weak reference count.
RefCount *	RefCountPtr ()
	Return pointer to the reference count structure.

Static Public Member Functions
static void	Write (int level, const String &message)
	Write to the log. If logging level is higher than the level of the message, the message is ignored.
static void	WriteRaw (const String &message, bool error=false)
	Write raw output to the log.
Static Public Member Functions inherited from Urho3D::Object
static const TypeInfo *	GetTypeInfoStatic ()
	Return type info static.

Private Member Functions
	URHO3D_OBJECT (Log, Object)
void	HandleEndFrame (StringHash eventType, VariantMap &eventData)
	Handle end of frame. Process the threaded log messages.

Private Attributes
Mutex	logMutex_
	Mutex for threaded operation.
List< StoredLogMessage >	threadMessages_
	Log messages from other threads.

int	level_
	Logging level.
bool	timeStamp_
	Timestamp log messages flag.
bool	inWrite_
	In write flag to prevent recursion.
bool	quiet_
	Quiet mode flag.

Additional Inherited Members
Protected Attributes inherited from Urho3D::Object
Context *	context_
	Execution context.
