Method: ClientSqueak#initialize

Defined in:

lib/mapsqueak.rb

#initialize(squeak) ⇒ ClientSqueak

Initialize a new squeak which must be in an allowable format Must set: latitude, longitude, text, and duration json - a String representation of a JSON object

e.g. {\"squeak\":{\"latitude\":\"54\",\"longitude\":\"-1.5\",\"duration\":\"2\",\"text\":\"Another squeak!\"}}

xml - a String representation of an XML blob

e.g. <squeak><latitude>54</latitude><longitude>-1.5</longitude><text>Another squeak!</text><duration>2</duration></squeak>

hash - a hash representation of a squeak

e.g. {:squeak => {:latitude=> 54, :longitude=>-1.69, :text => "Another squeak!", :duration => 2}}
OR if you are lazy (like me) you can just specify the inner hash:
e.g. {:latitude=> 54, :longitude=>-1.69, :text => "Another squeak!", :duration => 2}
