    def full_name_parts
      parts =
        case (parent = self.parent)

          parent.full_name_parts
        when nil
          [:""]
        else
          # e.g. self::Foo, (var)::Bar = baz
          raise ConstantPathNode::DynamicPartsInConstantPathError, "Constant target path contains dynamic parts. Cannot compute full name"
        end

      if (name = self.name).nil?
        raise ConstantPathNode::ErrorRecoveryNodesInConstantPathError, "Constant target path contains error recovery nodes. Cannot compute full name"
      end

      parts.push(name)
    end

Returns the list of parts for the full name of this constant path. For example: [:Foo, :Bar]

name → Symbol | nil
Source

    # File lib/prism/node.rb, line 9125
    def name
      @name
    end

Returns the `name` attribute.

parent → Node | nil

    # File lib/prism/node.rb, line 9115
    def parent
      @parent
    end

Returns the `parent` attribute.

## Locations

### Public Instance Methods

delimiter_loc → Location
Source

    # File lib/prism/node.rb, line 9136
    def delimiter_loc

      return location if location.is_a?(Location)
      @delimiter_loc = Location.new(source, location >> 32, location & 0xFFFFFFFF)
    end

Returns the `Location` represented by `delimiter_loc`.

name_loc → Location
Source

    # File lib/prism/node.rb, line 9158
    def name_loc
      location = @name_loc
      return location if location.is_a?(Location)
      @name_loc = Location.new(source, location >> 32, location & 0xFFFFFFFF)
    end

Returns the `Location` represented by `name_loc`.
