Data Types

DKUtil::Config supports 3 primitive data types, string variants and their array type(collection).

• Integer
• Double
• Boolean
• String

Declaring

To declare configuration data, initialize them with key field and optional section field.

using namespace DKUtil::Alias;                    // type alias

Integer myInt64Data{ "MyIntDataKey", "General" }; // std::int64_t
Double myDoubleData{ "MyDoubleKey", "General" };  // double
Boolean myBoolData{ "MyBoolKey" };                // bool
String myStringData{ "MyStringKey" };             // std::basic_string<char>

Section

Section field is optional and unnamed sections will be put under Global. Section is also ignored for JSON.

Accessing

The data can be accessed by operator * as if it were a pointer, or the const getter method get_data()/get_collection().

Collection on Singular Data

When the data is singular but called with get_collection(), a size-1 collection will be returned with the singular data only.

If the data is a collection, the reference of its members can be accessed by operator [] with index. There are two exceptions to this:

• The first element will be returned if the data is not a collection.
• The last element will be returned if the index is out of bound.

is_collection() can be used, or get_size() which will return 0 if it's not a collection.

WARNING

This behavior is planned to change with internal exception handling
