Implementation of efficient string concatenation.
|
|
|
|
The whole system is built around two basic template classes:
|
|
- ToStringHelper< T > - for each T it can give the length of the resulting string representation and can write
|
|
this string representation to a buffer
|
|
- O(U)StringConcat< T1, T2 > - operator+ now, instead of creating O(U)String object, returns only this helper object,
|
|
that keeps a reference to both operator+ operands; only when converted to O(U)String it will actually create
|
|
the resulting string object using ToStringHelper, creating directly the resulting object without any string
|
|
intermediate objects
|
|
As all the code is inline methods, it allows for extensive optimization and will usually result in very effective code
|
|
(even surpassing strlen/strcat and equalling handwritten), while allowing for very easy and intuitive syntax.
