(C++) Opaque pointer

In general, 'Opaque' denotes the following [1]:

1. Not allowing light to pass through; not transparent
2. (of a statement,piece of writing,etc) not clear, difficult to understand

In C++, an opaque pointer is a pointer to a declared, but undefined class [2].

Opaque pointers are used in, among others, the pimpl idiom.

One of the advantages of using opaque pointers is an increase in compile speed.
