-// This file implements a universal value printer that can print a |
-// value of any type T: |
-// |
-// void ::testing::internal::UniversalPrinter<T>::Print(value, ostream_ptr); |
-// |
-// A user can teach this function how to print a class type T by |
-// defining either operator<<() or PrintTo() in the namespace that |
-// defines T. More specifically, the FIRST defined function in the |
-// following list will be used (assuming T is defined in namespace |
-// foo): |
-// |
-// 1. foo::PrintTo(const T&, ostream*) |
-// 2. operator<<(ostream&, const T&) defined in either foo or the |
-// global namespace. |
-// |
-// If none of the above is defined, it will print the debug string of |
-// the value if it is a protocol buffer, or print the raw bytes in the |
-// value otherwise. |
-// |
-// To aid debugging: when T is a reference type, the address of the |
-// value is also printed; when T is a (const) char pointer, both the |
-// pointer value and the NUL-terminated string it points to are |
-// printed. |
-// |
-// We also provide some convenient wrappers: |
-// |
-// // Prints a value to a string. For a (const or not) char |
-// // pointer, the NUL-terminated string (but not the pointer) is |
-// // printed. |
-// std::string ::testing::PrintToString(const T& value); |
-// |
-// // Prints a value tersely: for a reference type, the referenced |
-// // value (but not the address) is printed; for a (const or not) char |
-// // pointer, the NUL-terminated string (but not the pointer) is |
-// // printed. |
-// void ::testing::internal::UniversalTersePrint(const T& value, ostream*); |
-// |
-// // Prints value using the type inferred by the compiler. The difference |
-// // from UniversalTersePrint() is that this function prints both the |
-// // pointer and the NUL-terminated string for a (const or not) char pointer. |
-// void ::testing::internal::UniversalPrint(const T& value, ostream*); |
-// |
-// // Prints the fields of a tuple tersely to a string vector, one |
-// // element for each field. |
-// std::vector<string> UniversalTersePrintTupleFieldsToStrings( |
-// const Tuple& value); |
-// |
-// Known limitation: |
-// |
-// The print primitives print the elements of an STL-style container |
-// using the compiler-inferred type of *iter where iter is a |
-// const_iterator of the container. When const_iterator is an input |
-// iterator but not a forward iterator, this inferred type may not |
-// match value_type, and the print output may be incorrect. In |
-// practice, this is rarely a problem as for most containers |
-// const_iterator is a forward iterator. We'll fix this if there's an |
-// actual need for it. Note that this fix cannot rely on value_type |
-// being defined as many user-defined container types don't have |
-// value_type. |
