Detailed Description

template<typename T>
class UT_COWValue< T >::Rep

The actual control block for a value referenced by (potentially multiple) UT_COWValues

These can be in one of three states:

• unique: only one UT_COWValue has mutable access to the data stored
• nonunique: multiple UT_COWValues have const access to the data stored
• immortal: an arbitrary number of UT_COWValues have const access to the read-only data stored

Immortal Reps are used to provide a cheap global default-constructed version of the contained type.
