Detailed Description

A mutex locked object smart pointer helper class.

This is particularly useful in referencing objects which will be protected by the mutex protect function. When the pointer falls out of scope, the protecting mutex is also released. This is meant to be used by the typed mutex_pointer template.

ucommon::auto_protect::operator bool ( )
inline

Test if the pointer is referencing an object.

Returns
true if the pointer is currently referencing an object.

Definition at line 1345 of file thread.h.

bool ucommon::auto_protect::operator! ( )
inline

Test if the pointer is not set.

Returns
true if the pointer is not referencing anything.

void ucommon::auto_protect::operator= ( void *  object)

Set our pointer to a specific object.

If the pointer currently references another object, the associated mutex is released. The pointer references our new object and that new object is locked.

Parameters
objectto assign to.
void ucommon::auto_protect::release ( void  )

Manually release the pointer.

This releases the mutex.
