Sass::Selector::AbstractSequence

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_a` method that returns an array of strings and script nodes.

Attributes

filename[R]

The name of the file in which this selector was declared.

@return [String, nil]

line[R]

The line of the Sass template on which this selector was declared.

@return [Fixnum]

Public Instance Methods

==(other) click to toggle source
Alias for: eql?
eql?(other) click to toggle source

Checks equality between this and another object.

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

@param other [Object] The object to test equality against @return [Boolean] Whether or not this is equal to `other`

# File lib/sass/selector/abstract_sequence.rb, line 57
def eql?(other)
  other.class == self.class && other.hash == self.hash && _eql?(other)
end
Also aliased as: ==
filename=(filename) click to toggle source

Sets the name of the file in which this selector was declared, or `nil` if it was not declared in a file (e.g. on stdin). This also sets the filename for all child selectors.

@param filename [String, nil] @return [String, nil]

# File lib/sass/selector/abstract_sequence.rb, line 35
def filename=(filename)
  members.each {|m| m.filename = filename}
  @filename = filename
end
hash() click to toggle source

Returns a hash code for this sequence.

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

@return [Fixnum]

# File lib/sass/selector/abstract_sequence.rb, line 46
def hash
  @_hash ||= _hash
end
line=(line) click to toggle source

Sets the line of the Sass template on which this selector was declared. This also sets the line for all child selectors.

@param line [Fixnum] @return [Fixnum]

# File lib/sass/selector/abstract_sequence.rb, line 24
def line=(line)
  members.each {|m| m.line = line}
  @line = line
end
to_s() click to toggle source

Converts the selector into a string. This is the standard selector string, along with any SassScript interpolation that may exist.

@return [String]

# File lib/sass/selector/abstract_sequence.rb, line 66
def to_s
  to_a.map {|e| e.is_a?(Sass::Script::Node) ? "\#{#{e.to_sass}}" : e}.join
end
