Description

This abstract interface provides a means for an algorithm to generically obtain a modifiable, contiguous character buffer of prescribed size. As the author of an algorithm simply declare an rvalue reference as a parameter type.

Instances of this type are intended only to be used once and then destroyed.

Example

The declared function accepts any temporary instance of arg to be used for writing:

void algorithm( string_token::arg&& dest );

To implement the interface for your type or use-case, derive from the class and implement the prepare function.
