    # File lib/prism/node.rb, line 14491
    def self.type

    end

Return a symbol representation of this node type. See ‘Node::type`.

### Public Instance Methods

=== (other)
Source

    # File lib/prism/node.rb, line 14497
    def ===(other)
      other.is_a?(PinnedExpressionNode) &&
        (expression === other.expression) &&
        (operator_loc.nil? == other.operator_loc.nil?) &&
        (lparen_loc.nil? == other.lparen_loc.nil?) &&
        (rparen_loc.nil? == other.rparen_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.
