Class Method Details

.register(*args) ⇒ Object

Register one or more handler methods with this outputter. Passcard will then be able to use these methods to get the output from the outputter. For example, if you have an HtmlOutputter, you could do:

register :to_html, :to_xml

You could then do a Passcard.to_png and get the result of that method. The class which registers the method will receive the generator instance as the only argument, and the default implementation of initialize puts that into the passcard accessor.

You can also have different method names in the outputter by providing a hash:

register to_html: :create_html, to_xml: :create_xml

Raises:
