Instance Method Details

#changed? ⇒ Boolean

If the file at path has changed this method returns true. It always returns true, if the attribute reload_time is set to a value < 0. If reload_time is set to a value >= 0, it will return true only after reload_time seconds (before that time has passed nil is returned), even if the file has changed.

Returns:

  • (Boolean)

def changed?
  return true if @cache.reload_time and @cache.reload_time < 0
  if @cache.reload_time and Time.now - @template.mtime < @cache.reload_time
    return
  end
  @template.mtime != @mtime
end

#compile ⇒ Object

Compile the file at path with a Flott instance and return it. This implies that the template attribute is set to the return value for later reuse without compiling.
