Detailed Description

template<class T>
class Foam::UPtrList< T >

A list of pointers to objects of type <T>, without allocation/deallocation management of the pointers - this is to be done elsewhere. The operator[] returns a reference to the object, not the pointer.

Note: The class definition is such that it contains a list of pointers, but itself does not inherit from a list of pointers since this would wreak havoc later with inheritance resolution.
