It makes use of MockFunction easier by allowing it to accept more F arguments
|
||||
than just function signatures.
|
||||
|
||||
Specializations provided here cover only a signature type itself and
|
||||
std::function. However, if need be it can be easily extended to cover also other
|
||||
types (like for example boost::function).
|

Specializations provided here cover a signature type itself and any template
|
||||
that can be parameterized with a signature, including std::function and

boost::function.
