Public Class methods

new(before, mid, after, wb, wa, originally_text = false)

Interpolation in a property is of the form `before #{mid} after`.

@param before [Node] The SassScript before the interpolation @param mid [Node] The SassScript within the interpolation @param after [Node] The SassScript after the interpolation @param wb [Boolean] Whether there was whitespace between `before` and `#{` @param wa [Boolean] Whether there was whitespace between `}` and `after` @param originally_text [Boolean] 

  Whether the original format of the interpolation was plain text,
  not an interpolation.
  This is used when converting back to SassScript.

Public Instance methods

children()

Protected Instance methods

_perform(environment)

Evaluates the interpolation.

@param environment [Sass::Environment] The environment in which to evaluate the SassScript @return [Sass::Script::String] The SassScript string that is the value of the interpolation
