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

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 == self.hash && _eql?(other)
end

#hash ⇒ Fixnum

Returns a hash code for this sequence.

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

Returns:

  • (Fixnum)

#to_s ⇒ String
