Defined in:
lib/patience/area.rb

Overview

Patience::Area provides area objects, that consist of piles. The goal of this class is to assemble piles into a logical bundle with a few common methods, so they could be controlled via only one interface. Basically, this class is useless on its own. The purpose of Area is to be inherited by other classes, which are more verbose in their intentions. By default, Area object instantiates without any cards and only with one pile. Every new pile would be created empty, even though you feed some cards to the new object. All the cards you provide to the new object, wouldn’t be placed anywhere. You have to allocate them manually.

field = Area.new
field.piles #=> [#<Patience::Pile>]
filed.piles[0].pos #=> (0, 0)
field.pos #=> (0, 0)
