CSV::Row.new

CSV::Row.new(headers, fields, header_row = false) → csv_row

# File tmp/rubies/ruby-3.3.0/lib/csv/row.rb, line 105
def initialize(headers, fields, header_row = false)
  @header_row = header_row
  headers.each { |h| h.freeze if h.is_a? String }

  # handle extra headers or fields
  @row = if headers.size >= fields.size
    headers.zip(fields)
  else
    fields.zip(headers).each(&:reverse!)
  end
end

Returns the new CSV::Row instance constructed from arguments headers and fields; both should be Arrays; note that the fields need not be Strings:

Example

row = CSV::Row.new(['Name', 'Value'], ['foo', 0])
row # => #<CSV::Row "Name":"foo" "Value":0>

If the Array lengths are different, the shorter is nil-filled:

Example

row = CSV::Row.new(['Name', 'Value', 'Date', 'Size'], ['foo', 0])
row # => #<CSV::Row "Name":"foo" "Value":0 "Date":nil "Size":nil>

Each CSV::Row object is either a field row or a header row; by default, a new row is a field row; for the row created above:

Example

row.field_row? # => true
row.header_row? # => false

If the optional argument header_row is given as true, the created row is a header row:

Example

row = CSV::Row.new(['Name', 'Value'], ['foo', 0], header_row = true)
row # => #<CSV::Row "Name":"foo" "Value":0>
row.field_row? # => false
row.header_row? # => true
