Constructor Details

#initialize(value) ⇒ SDLSimpleType

Creates a new instance of an SDL type.

Invokes from_ methods of subtypes, if value is not subtype of the wrapped Ruby type.

@param value

The instance value. Unless the value class is a subclass of the wrapped Ruby class,
perform conversion by invoking +from_#{classname}+, e.g. +from_string+ or +from_integer+.

Subclasses are expected to implement this conversion function.
