Detailed Description

ALValue is a class to manipulate differente value type.

It's using to convert multiple value type to one type, to ease the communication or storage of differente values.

Member Enumeration Documentation

enum AL::ALValue::Type

Type of ALValue.

Warning:

this enum order matter, it is used in paramtype.h

double support cannot be added. This would break:

     ALValue v;
     v = 0.1;

sometime the compiler will use the double constructor instead of the float one, breaking too much user code.

Enumerator:

TypeInvalid	Invalid type.
TypeArray	Array type.
TypeBool	Boolean type.
TypeInt	Integer type.
TypeFloat	Float type.
TypeString	String type.
TypeObject	Object type.
TypeBinary	Base64 type.
