The
template formal argument list can contain three
|
|
|
different
kinds of arguments:
|
|
|
|
• |
identifiers
that represent type dependencies,
|
|
|
|
• |
identifiers
that represent values, and i
|
|
|
|
• |
dentifiers
that represent type dependencies based on a
|
|
template
class.
|
|
|
| • |
A
type dependency allows the identifier listed to be
|
|
|
substituted
for the data type specified by the client at
|
|
|
instantiation
time. More than one identifier can be listed,
|
|
|
each
prefaced by the keyword class or typename to
|
|
|
indicate
that this is a type dependency.
