Public Class Methods
from_binary_string(binary_string)
click to toggle source
Create an instance from a binary string, e.g. from a NXT
record RDATA:
# File lib/dnsruby/resource/NXT.rb, line 271 def self.from_binary_string(binary_string) new(BitMapping.binary_string_to_number(binary_string)) end
from_names_string(names_string)
click to toggle source
Create an instance from a string containing type names separated by spaces e.g. “A TXT
NXT”
# File lib/dnsruby/resource/NXT.rb, line 260 def self.from_names_string(names_string) type_codes = BitMapping.names_string_to_codes(names_string) from_type_codes(type_codes) end
from_type_codes(type_codes)
click to toggle source
Create an instance from type numeric codes (e.g. 30 for NXT
).
# File lib/dnsruby/resource/NXT.rb, line 266 def self.from_type_codes(type_codes) new(BitMapping.set_bit_position_array_to_number(type_codes)) end
new(bitmap_number)

The constructor is made private so that the name of the method called to create the instance reveals to the reader the type of the initial data.
# File lib/dnsruby/resource/NXT.rb, line 278 def initialize(bitmap_number) NxtTypes.assert_legal_bitmap_value(bitmap_number) @bitmap = Bitmap.from_number(bitmap_number) end
Public Instance Methods
to_binary_string()
click to toggle source
Returns a binary string representing this data, in as few bytes as possible (i.e. no leading zero bytes).
# File lib/dnsruby/resource/NXT.rb, line 285 def to_binary_string bitmap.to_binary_string end
to_s()
click to toggle source
Output types in dig format, e.g. “A AAAA NXT”
# File lib/dnsruby/resource/NXT.rb, line 295 def to_s type_codes = bitmap.to_set_bit_position_array NxtTypes.codes_to_string(type_codes) end
to_type_array()
click to toggle source
Returns the instance's data as an array of type codes.
# File lib/dnsruby/resource/NXT.rb, line 290 def to_type_array bitmap.to_set_bit_position_array end
