Constructor Details

#initialize(raw_data) ⇒ Base

Public: Initialize a Poe Watch item. It will automatically create instance variables, setters, getters for instance variables, and question mark methods for variables with boolean values. It is to note that any hash or array of hashes will be transformed into an OpenStruct.

raw_data - An array of hash

Returns an instance of the class.
