Detailed Description

RefCountedBase class adds intrusive reference counting support to the Base class. It should be used together with boost::intrusive_ptr and the ML_REFCOUNTED_PTR macro.

Member Function Documentation

decRefCount()

virtual void ml::RefCountedBase::decRefCount ( ) const

virtual

Decreases the reference count (object will be deleted if the reference count is decremented to 0).

virtual void ml::RefCountedBase::incRefCount ( ) const

virtual

Increases the reference count.

isRefCountedBase()

updateReferenceCountingIfSupported()

void ml::RefCountedBase::updateReferenceCountingIfSupported ( Base * oldValue, Base * newValue, bool & isRefCountedBase )

static

Helper method that handles incrementing/decrementing of the reference count if base instances support it. It decrements the reference count of oldValue if supported and not NULL. It increments the reference count of newValue if supported and not NULL. isRefCountedBase must indicate whether oldValue supported reference counting. isRefCountedBase will be set to true if the newValue supports reference counting.
