Detailed Description

All the registered callback functions can take no argument, a reference to an UVar, or any type convertible from UValue.

The last kind will be called with the current value contained in the UVar.

Function Documentation

void urbi::UObject::UNotifyAccess	(	UVar &	v,
		void(UObject::*)(UVar &)	fun
	)

Call a function each time a variable is accessed.

Parameters:

v	the variable to monitor.
fun	the function to call each time the variable v is accessed. The function is called right before the variable v is accessed, giving fun the opportunity to modify it.

Referenced by sensor::sensor(), and uaccess::uaccess().

void urbi::UObject::UNotifyChange	(	UVar &	v,
		void(UObject::*)(UVar &)	fun
	)

Call a function each time a variable is modified.

Parameters:

v	the variable to monitor.
fun	the function to call each time the variable v is modified. The function is called rigth after the variable v is modified.

template<typename T >

void urbi::UObject::UNotifyChange	(	UVar &	v,
		void(UObject::*)(T)	fun
	)

UnotifyChange() variant that passes the UVar value as argument to your callback function.

void urbi::UObject::UNotifyThreadedAccess	(	UVar &	v,
		void(UObject::*)(UVar &)	fun,
		LockMode	m
	)

void urbi::UObject::UNotifyThreadedAccess	(	UVar &	v,
		void(UObject::*)(UVar &)	fun,
		LockSpec	s
	)

void urbi::UObject::UNotifyThreadedChange	(	UVar &	v,
		void(UObject::*)(UVar &)	fun,
		LockMode	m
	)

Similar to UNotifyChange(), but run function in a thread.

Parameters:

v	the variable to monitor.
fun	the function to call.
m	the locking mode to use.

void urbi::UObject::UNotifyThreadedChange	(	UVar &	v,
		void(UObject::*)(UVar &)	fun,
		LockSpec	s
	)

Similar to UNotifyChange(), but run function in a thread.

Parameters:

v	the variable to monitor.
fun	the function to call.
s	the locking specifications to use.
