Defined in:
.ruby-sass/lib/sass/selector/abstract_sequence.rb

Overview

The abstract parent class of the various selector sequence classes.

All subclasses should implement a `members` method that returns an array of object that respond to `#line=` and `#filename=`, as well as a `to_s` method that returns the string representation of the selector.

Instance Method Details

#eql?(other) ⇒ Boolean Also known as: ==

Checks equality between this and another object.

Subclasses should define `#_eql?` rather than overriding this method, which handles checking class equality and hash equality.

Parameters:

  • other (Object) —

    The object to test equality against

Returns:

  • (Boolean) —

    Whether or not this is equal to `other`

def eql?(other)
  other.class == self.class && other.hash == hash && _eql?(other)
end

#hash ⇒ Integer

Returns a hash code for this sequence.

Subclasses should define `#_hash` rather than overriding this method, which automatically handles memoizing the result.

Returns:

  • (Integer)

def hash
  @_hash ||= _hash
end

#invisible? ⇒ Boolean

Whether or not this selector should be hidden due to containing a placeholder.

Returns:

  • (Boolean)

def invisible?
  @invisible ||= members.any? do |m|
    next m.invisible? if m.is_a?(AbstractSequence) || m.is_a?(Pseudo)
    m.is_a?(Placeholder)
  end
end

#specificity ⇒ Integer, Range

Returns the specificity of the selector.

The base is given by SPECIFICITY_BASE. This can be a number or a range representing possible specificities.

Returns:

  • (Integer, Range)

def specificity
  _specificity(members)
end

#to_s(opts = {}) ⇒ String

Returns the selector string.

Parameters:

  • opts (Hash) (defaults to: {}) —

    rendering options.

  • placeholders (Hash) —

    a customizable set of options

Options Hash (opts):

  • :style (Symbol) —

    The css rendering style.

Returns:

  • (String)
