mrdocs::dom
Objects representing JSON‐like values.
Description
This class is a variant‐like container for holding any kind of value that can be represented in JSON, with extensions for functions and "safe strings".
The class supports the following types:
-
Undefined
-
Null
-
Boolean
-
Integer
-
String
-
SafeString
-
Array
-
Object
-
Function
The class provides type‐safe accessors for each type, as well as methods to check the type of the contained value.
Example:
{.cpp}
dom::Value v1 = 42; // Integer
dom::Value v2 = "Hello, World!"; // String
dom::Value v3 = dom::Array{v1, v2}; // Array
if (v1.isInteger())
{
std::cout << "v1 is an integer: " << v1.getInteger() << "\n";
}
if (v2.isString())
{
std::cout << "v2 is a string: " << v2.getString() << "\n";
}
if (v3.isArray())
{
std::cout << "v3 is an array with " << v3.getArray().size() << " elements.\n";
