With
class templates, we simply write one class and shift
|
|
|
the
burden of creating multiple instances of that class to
|
|
|
the
compiler.
|
|
| • |
The
compiler automatically generates as many instances of
|
|
that
class as is required to meet the client's demands
|
|
|
without
unnecessary duplication.
|
|
| • |
Specialized
(and partially specialized) template classes can
|
|
be
used to handle special cases that arise.
|
|
| • |
The
syntax for implementing class templates is similar to
|
|
|
that
of defining and declaring classes themselves. We
|
|
|
simply
preface the class definition or declaration with the
|
|
|
keyword
template followed by a parameterized list of type
|
|
|
dependencies.
