Yeah, but how is this related to use of 'this->'?
The example above is not ideal, but using operator < and operator == on
the argument "that", which is conceivable.
Here is an example where operator > is being implemented for a
symmetric cipher key:
bool operator > (const Key &that) const
{
unsigned int i = b;
while (i--)
{
if (this->buffer[i] > that.buffer[i])
return true;
if (this->buffer[i] < that.buffer[i])
return false;
}
return false;
}
Using "this" provides a bit of visual balance.
And how (unnatural)
would you refer to 'this' other than '*this' in this case? :-)
operator >, but as mentioned, this was a bad example.
