new (source, node_id, location, flags, else_keyword_loc, statements, end_keyword_loc)
Source

    # File lib/prism/node.rb, line 6711
    def initialize(source, node_id, location, flags, else_keyword_loc, statements, end_keyword_loc)
      @source = source

      @else_keyword_loc = else_keyword_loc
      @statements = statements
      @end_keyword_loc = end_keyword_loc

Initialize a new `ElseNode` node.

### Public Instance Methods

=== (other)
Source

    # File lib/prism/node.rb, line 6825
    def ===(other)
      other.is_a?(ElseNode) &&
        (else_keyword_loc.nil? == other.else_keyword_loc.nil?) &&
        (statements === other.statements) &&
        (end_keyword_loc.nil? == other.end_keyword_loc.nil?)
    end

Implements case-equality for the node. This is effectively == but without comparing the value of locations. Locations are checked only for presence.
