Instance Method Details

#delta ⇒ Object

Returns how much time elapsed since the last emission



189
 
# File 'lib/roby/state/events.rb', line 189

def delta; Time.now - last_value end

#has_sample? ⇒ Boolean

Always true, as we can always measure time



187
 
# File 'lib/roby/state/events.rb', line 187

def has_sample?; true end

#read ⇒ Object

Returns the current time



191
 
# File 'lib/roby/state/events.rb', line 191

def read;  Time.now end
