/* json11 * * json11 is a tiny JSON library for C++11, providing JSON parsing and serialization. * * The core object provided by the library is json11::Json. A Json object represents any JSON * value: null, bool, number (int or double), string (std::string), array (std::vector), or * object (std::map). * * Json objects act like values: they can be assigned, copied, moved, compared for equality or * order, etc. There are also helper methods Json::dump, to serialize a Json to a string, and * Json::parse (static) to parse a std::string as a Json object. * * Internally, the various types of Json object are represented by the JsonValue class * hierarchy. * * A note on numbers - JSON specifies the syntax of number formatting but not its semantics, * so some JSON implementations distinguish between integers and floating-point numbers, while * some don't. In json11, we choose the latter. Because some JSON implementations (namely * Javascript itself) treat all numbers as the same type, distinguishing the two leads * to JSON that will be *silently* changed by a round-trip through those implementations. * Dangerous! To avoid that risk, json11 stores all numbers as double internally, but also * provides integer helpers. * * Fortunately, double-precision IEEE754 ('double') can precisely store any integer in the * range +/-2^53, which includes every 'int' on most systems. (Timestamps often use int64 * or long long to avoid the Y2038K problem; a double storing microseconds since some epoch * will be exact for +/- 275 years.) */ /* Copyright (c) 2013 Dropbox, Inc. * * Permission is hereby granted, free of charge, to any person obtaining a copy * of this software and associated documentation files (the "Software"), to deal * in the Software without restriction, including without limitation the rights * to use, copy, modify, merge, publish, distribute, sublicense, and/or sell * copies of the Software, and to permit persons to whom the Software is * furnished to do so, subject to the following conditions: * * The above copyright notice and this permission notice shall be included in * all copies or substantial portions of the Software. * * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
