Instance Method Details

#do(f) ⇒ Object

This function must be called with a FigureMaker object to draw the contents of the TiogaElement onto it. It calls #real_do, which should be redefined by the children. You can redefine do too if you need another debugging output.

def do(f)
  debug { "plotting #{self.inspect}" }
  @gp_cache = {}
  real_do(f)
end

#inspect(prefix = "") ⇒ Object

We plot everything but parent. If a prefix is given, it is prepended to all lines but the first (for indentation)
