Module Dnsruby::RR::NXT::NxtTypes
In: lib/dnsruby/resource/NXT.rb

Methods used to manipulate the storage and representation of record types as stored in NXT record bitmaps.

Methods

assert_legal_bitmap_value   binary_string_to_codes   binary_string_to_names   code_to_name   codes_to_binary_string   codes_to_names   codes_to_string   legal_code_value?   name_to_code   names_string_to_codes   names_to_codes  

Constants

MAX_BITMAP_NUMBER_VALUE = (2 ** 128) - 1 - 1   Maximum bitmap size is 128 bytes; since it‘s zero offset values are 0..(2 ** 128 - 1). However, the least significant bit must not be set, so the maximum is 1 less than that.

Public Instance methods

assert_legal_bitmap_value(number)

Assert that the specified number is a legal value with which to instantiate a NXT type bitmap. Raise on error, do nothing on success.

binary_string_to_codes(binary_string)

From a binary string of type code bits, return an array of type codes.

binary_string_to_names(binary_string)

From a binary string of type code bits, return an array of type names.

code_to_name(number)

Convert a numeric type code to its corresponding name (e.g. "A" => 1). Unknown types are named "TYPE#{number}".

codes_to_binary_string(codes)

From an array of type codes, return a binary string.

codes_to_names(codes)

For the given array of type codes, return an array of their corresponding names.

codes_to_string(codes)

Generate a string containing the names corresponding to the numeric type codes. Sort it by the numeric type code, ascending.

name_to_code(name)

Convert a type name to its corresponding numeric type code. Names matching /^TYPE(\d+)$/ are assumed to have a code corresponding to the numeric value of the substring following ‘TYPE’.

names_string_to_codes(name_string)

For the specified string containing names (e.g. ‘A NS’), return an array containing the corresponding codes.

names_to_codes(names)

For a given array of type names, return an array of codes.
