Instance Method Details

#synthesize(options) ⇒ Object

Public: Defines a synthesizer for the implementation class. It takes an Hash argument to define the class the object should by synthesized and an additional adapter.

options - A Hash containing synthesize configurations

:from   - The class the implementation and proxy object has to
          synthesized (String or Constant)
:adapter- An optional class name that points to a implemented
          Synthesizer. Defaults to
          Seatbelt::Synthesizers::Document

#synthesize_map(map = nil) ⇒ Object

Public: Combined getter and setter for a map of attributes that should be used for synthesizing the proxy and the implementation object.

map=nil - a Hash of proxy attributes as keys and implementation object

attributes as values.

If map is nil, it returns the synthesize map (or an Empty hash if not previously set).
