Detailed Description

template<typename T>
class UT_COWReadHandle< T >

This is a copy-on-write shared pointer to data. If you create a writehandle, it will uniquify the underlying data. Do not pass references to handles or pointers to them around. This can cause you to invalidate the tracking of copies. In any case, passing by value is fast.

Read Handles are copies of the original handle that have their internal data exposed. You are not allowed to edit them, so many read handles may be sharing the same underlying data.
