class Sass::Selector::AbstractSequence

method that returns an array of strings and script nodes.
of object that respond to ‘#line=` and `#filename=`, as well as a `to_a`
All subclasses should implement a `members` method that returns an array
The abstract parent class of the various selector sequence classes.

def _specificity(arr) 

def _specificity(arr)
  spec = 0
  arr.map {|m| spec += m.is_a?(String) ? 0 : m.specificity}
  spec
end

def eql?(other)

Returns:
  • (Boolean) - Whether or not this is equal to `other`

Parameters:
  • other (Object) -- The object to test equality against 
def eql?(other)
  other.class == self.class && other.hash == self.hash && _eql?(other)
end

def filename=(filename)

Returns:
  • (String, nil) -

Parameters:
  • filename (String, nil) -- 
def filename=(filename)
  members.each {|m| m.filename = filename}
  @filename = filename
end

def has_placeholder?

Checks recursively.
Whether or not this selector sequence contains a placeholder selector. 
def has_placeholder?
  @has_placeholder ||=
    members.any? {|m| m.is_a?(AbstractSequence) ? m.has_placeholder? : m.is_a?(Placeholder)}
end

def hash

Returns:
  • (Fixnum) - 
def hash
  @_hash ||= _hash
end

def line=(line)

Returns:
  • (Fixnum) -

Parameters:
  • line (Fixnum) -- 
def line=(line)
  members.each {|m| m.line = line}
  @line = line
end

def specificity

Returns:
  • (Fixnum) - 
def specificity
  _specificity(members)
end

def to_s

Returns:
  • (String) - 
def to_s
  to_a.map {|e| e.is_a?(Sass::Script::Node) ? "\#{#{e.to_sass}}" : e}.join
