Amit, it means this code is valid: class Whatever; class Another { boost::shared_ptr< Whatever > ptr; }; Notice that the full definition of Whatever is not given. When you define the Another constructor, the class Whatever must be completely defined. Jason Winnebeck Amit Bhatia wrote:

Hello All, I have been trying to understand the smart pointer library. One thing that I did not understand was in the documentationin quite beginning:

"T may be an incomplete type at the point of smart pointer declaration. Unless otherwise specified, it is required that T be a complete type at points of smart pointer instantiation."

So what exactly does this incomplete/complete type mean? Does this have anything to do with the class pointed to being abstract /concrete ?

thanks, regards, amit.
