BDE 3.104.0 Highlights

Continued Addition of C++17 Type Aliases

This release adds bsl:: aliases for the C++17 features in bsl_functional.h, and bsl::string_view. Additionally, implementations (including C++03 implementations) for bsl::clamp, bsl::erase, and bsl::erase_if are provided. This is part of the general effort to simplify the use of bsl:: names, and in general better support C++17.

New Component, bdlb_printadapter

BDE 3.104.0 introduced a new component bdlb_printadapter the simplifies streaming an object that is printable with bdlb::PrintMethods. These are typically objects implementing the standard BDE print method, bsl::ostream& print(bsl::ostream& stream, int level, int spacesPerLevel).

This adapter is helpful when streaming potentially complex objects implementing print in a more human readable (multi-line) format. operator<< typically outputs on a single line, which can be hard to read for complex nested objects. For example (using C++17):

void processRequest(const Request& request) {

    // ...

    // Calls 'reqeust.print(stream, 1, 3)':

    BALL_LOG_ERROR << "Failer to process request: " << bdlb::PrintAdaptor(&request, 1, 3);

    return -1;
}

Fixed requests:
