arg [constructor] | Constructors |
~arg [destructor] [virtual] | Virtual destructor |
operator= [deleted] | Assignment operators |
prepare [virtual] | Return a modifiable character buffer |
This abstract interface provides a means for an algorithm to generically obtain a modifiable, contiguous character buffer of prescribed size.
A StringToken
should be derived from this class. As the author of an algorithm using a StringToken
, simply declare an rvalue reference as a parameter type.
Instances of this type are intended only to be used once and then destroyed.
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.
