set() [1/2]

template<typename Scalar >

void Json::Object::set	(	std::string const &	key,
		Scalar const &	value
	)

Set a scalar value in the Object for a key.

A JSON scalar is a single value - a number, string, boolean, nullptr or a Json::Value.

set() throws an exception if this object is disabled (which means that one of its children is enabled).

In a debug build, set() also throws an exception if the key has already been set() before.

An operator[] is provided to allow writing object["key"] = scalar;.
