|
| -// 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 as the given type to a string.
|
| -// string ::testing::internal::UniversalPrinter<T>::PrintToString(value);
|
| -//
|
| -// // Prints a value tersely: for a reference type, the referenced
|
| -// // value (but not the address) is printed; for a (const) 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) 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.
