Does this patch for boost/scoped_array.hpp look useful?
< T * release() // never throws
< T * result = ptr;
< ptr = 0;
< return result;
It allows me to use boost::scoped_array almost like an auto_ptr:
boost::scoped_array<int> result(new int[size]);
// do something to result
// if an exception is thrown result will be cleaned up
// code is still exception safe
I wouldn't need this if
- we had std::auto_array (don't think it exists)
- std::vector<int>(size) wouldn't do the default construction of all elements
and I didn't care about having two pointers instead of just one (sometimes I
actually do care)
- boost::scoped_array::ptr was protected instead of private so that I could
inherit and add release()
Are there arguments for not adding release()?
