Detailed Description

For internal use only.

Reference counted internal classes should inherit from RefCntBase.

This gives the object a reference count used by RefCntPtr.

Constructor & Destructor Documentation

Xapian::Internal::RefCntBase::RefCntBase

(

const RefCntBase &

)

[inline, protected]

The copy constructor.

This is protected since it'll only be used by derived classes, which should only rarely need copying (this is, after all, a refcount implementation). Sometimes it's needed, though, since we need to zero ref_count in the copy.

[inline]

The constructor, which initialises the ref_count to 0.

Member Data Documentation

ref_count_t Xapian::Internal::RefCntBase::ref_count [mutable]

The actual reference count.

It's mutable so we can have reference counting work with const pointers.
