21 "Array::IntSpan::Fields" brings the advantages of "Array::IntSpan" to
22 indices made of integer fields like an IP address and an ANSI SS7 point
23 code.
24
25 The number of integer and their maximum value is defined when calling
26 the constructor (or the "set_format" method). The example in the
27 synopsis defines an indice with 3 fields where their maximum values are
28 1,3,15 (or 0x1,0x3,0xf).
29
30 This module converts the fields into integer before storing them into
31 the Array::IntSpan module.
32
34 new (...)
35 The first parameter defines the size of the integer of the fields, in
36 number of bits. For an IP address, the field definition would be
37 "8,8,8,8".
38
40 All methods of Array::IntSpan are available.
41
42 set_format( field_description )
43 Set another field description. Beware: no conversion or checking is
44 done. When changing the format, old indices may become illegal.
45
46 int_to_field ( integer )
47 Returns the field representation of the integer.
48
49 field_to_int ( field )
50 Returns the integer value of the field. May craok if the fields values
51 are too great with respect to the filed description.
