template <class Impl>

class PolymorphicMatcher

Defined at line 617 of file ../../third_party/googletest/src/googletest/include/gtest/gtest-matchers.h

The PolymorphicMatcher class template makes it easy to implement a

polymorphic matcher (i.e. a matcher that can match values of more

than one type, e.g. Eq(n) and NotNull()).

To define a polymorphic matcher, a user should provide an Impl

class that has a DescribeTo() method and a DescribeNegationTo()

method, and define a member function (or member function template)

bool MatchAndExplain(const Value

value,

MatchResultListener* listener) const;

See the definition of NotNull() for a complete example.
