.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\f(CW\*(C`Array::IntSpan::Fields\*(C'\fR brings the advantages of \f(CW\*(C`Array::IntSpan\*(C'\fR
to indices made of integer fields like an \s-1IP\s0 address and an \s-1ANSI SS7\s0 point code.
.PP
The number of integer and their maximum value is defined when calling
the constructor (or the \f(CW\*(C`set_format\*(C'\fR method). The example in the
synopsis defines an indice with 3 fields where their maximum values
are 1,3,15 (or 0x1,0x3,0xf).
.PP
This module converts the fields into integer before storing them into
the Array::IntSpan module.
.SH "CONSTRUCTOR"
.IX Header "CONSTRUCTOR"
.SS "new (...)"
.IX Subsection "new (...)"
The first parameter defines the size of the integer of the fields, in
number of bits. For an \s-1IP\s0 address, the field definition would be
\&\f(CW\*(C`8,8,8,8\*(C'\fR.
.SH "METHODS"
.IX Header "METHODS"
All methods of Array::IntSpan are available.
.SS "set_format( field_description )"
.IX Subsection "set_format( field_description )"
Set another field description. Beware: no conversion or checking is
done. When changing the format, old indices may become illegal.
.SS "int_to_field ( integer )"
.IX Subsection "int_to_field ( integer )"
Returns the field representation of the integer.
.SS "field_to_int ( field )"
.IX Subsection "field_to_int ( field )"
Returns the integer value of the field. May craok if the fields values
are too great with respect to the filed description.
