# class Prism::PinnedExpressionNode

Represents the use of the `^` operator for pinning an expression in a pattern matching expression.

    foo in ^(bar)
           ^^^^^^

### Attributes

expression [R]

The expression used in the pinned expression

    foo in ^(bar)
             ^^^

### Public Instance Methods

=== (other)
Source

    # File lib/prism/node.rb, line 15573
    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.
