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

    # File lib/prism/node.rb, line 10822
    def initialize(source, node_id, location, flags, opening_loc, parts, closing_loc)
      @source = source

type ()
Source

    # File lib/prism/node.rb, line 10937
    def self.type
      :interpolated_string_node

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

### Public Instance Methods

=== (other)
Source

    # File lib/prism/node.rb, line 10943
    def ===(other)
      other.is_a?(InterpolatedStringNode) &&
        (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.
