new (source, node_id, location, flags, opening_loc, parts, closing_loc)
Source

    # File lib/prism/node.rb, line 11238
    def initialize(source, node_id, location, flags, opening_loc, parts, closing_loc)
      @source = source

    end

Initialize a new `InterpolatedMatchLastLineNode` node.

type ()

    # File lib/prism/node.rb, line 11393

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

### Public Instance Methods

=== (other)
Source

    # File lib/prism/node.rb, line 11399
    def ===(other)
      other.is_a?(InterpolatedMatchLastLineNode) &&
        (flags === other.flags) &&
        (opening_loc.nil? == other.opening_loc.nil?) &&
        (parts.length == other.parts.length) &&
        parts.zip(other.parts).all? { |left, right| left === right } &&
        (closing_loc.nil? == other.closing_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.
