Detailed Description

template<class T>
class net_instaweb::RefCountedObj< T >

If you can't inherit off RefCounted due to using a pre-existing class, you can use RefCountedObj instead. This however is limited to having a single type (so no polymorphism). It also has slightly different semantics in that it initializes to a default-constructed object and not NULL.

Member Function Documentation

template<class T>

void net_instaweb::RefCountedObj< T >::reset ( const T &  val )

inline

Sets the object to contain a new value, detaching it from any other RefCountedObj instances that were previously sharing data.

template<class T>

bool net_instaweb::RefCountedObj< T >::unique ( ) const

inline

Determines whether any other RefCountedObj objects share the same storage. This can be used to create copy-on-write semantics if desired.
