Defined in:
lib/effigy/selection.rb

Overview

Proxy class for performing transformations with a set selection.

Selections are created and returned when calling View#find without a block. Any methods called on the Selection will be forwarded to the given view with the given selector inserted at the front of the argument list.

All methods should return the Selection itself, so transformation methods can be chained on a selection.

Normally, Selections are not instantiated directly, but by calling View#find.

Examples:

view = Effigy::View.new
# same as calling view.remove_class('.active', 'inactive')
view.find('.active').remove_class('inactive')
