### Public Class Methods

new (source, node_id, location, flags, elements)
Source

    # File lib/prism/node.rb, line 19349
    def initialize(source, node_id, location, flags, elements)
      @source = source
      @node_id = node_id
      @location = location
      @flags = flags
      @elements = elements
    end

Initialize a new `KeywordHashNode` node.

### Public Instance Methods

elements → Array[AssocNode | AssocSplatNode]
Source

    # File lib/prism/node.rb, line 19458
    def elements
      @elements
    end

Returns the `elements` attribute.

## Flags

### Public Instance Methods

symbol_keys? ()
Source

    # File lib/prism/node.rb, line 19448
    def symbol_keys?
      flags.anybits?(KeywordHashNodeFlags::SYMBOL_KEYS)
    end

a keyword hash which only has `AssocNode` elements all with symbol keys, which means the elements can be treated as keyword arguments
