template <typename Impl>class PolymorphicAction
Defined at line 872 of file ../../third_party/googletest/src/googlemock/include/gmock/gmock-actions.h
The PolymorphicAction class template makes it easy to implement a
polymorphic action (i.e. an action that can be used in mock
functions of than one type, e.g. Return()).
To define a polymorphic action, a user first provides a COPYABLE
implementation class that has a Perform() method template:
class FooAction {
public:
template
<typename
Result, typename ArgumentTuple>
Result Perform(const ArgumentTuple
&
args) const {
// Processes the arguments and returns a result, using
// std::get
<N
>(args) to get the N-th (0-based) argument in the tuple.
}
...
};
Then the user creates the polymorphic action using
MakePolymorphicAction(object) where object has type FooAction. See
the definition of Return(void) and SetArgumentPointee
<N
>(value) for
complete examples.
