=head1 NAME
MARC::Spec::Subfield - subfield specification
=head1 SYNOPSIS
use MARC::Spec;
my $ms = MARC::Spec->new('245$a/0-2);
say ref $ms->subfields; # ARRAY
say ref $ms->subfields->[0]; # MARC::Spec::Subfield
=head1 DESCRIPTION
MARC::Spec::Subfield is the subfield specification of a L<MARC::Spec|MARC::Spec>.
See L<MARCspec - A common MARC record path language|http://marcspec.github.io/MARCspec/> for further
details on the syntax.
=head1 METHODS
Some methods are inherited from L<MARC::Spec::Structure|MARC::Spec::Structure>.
=head2 new
Create a new MARC::Spec::Subfield instance.
=head2 add_subspec(MARC::Spec::Subspec)
Appends a subspec to the array of the attribute subspecs. Parameter must be an instance of
L<MARC::Spec::Subspec|MARC::Spec::Subspec>.
Inherited from L<MARC::Spec::Structure|MARC::Spec::Structure>.
=head2 add_subspecs(ArrayRef[MARC::Spec::Subspec])
Appends subspecs to the array of the attribute subspecs. Parameter must be an ArrayRef and
elements must be instances of L<MARC::Spec::Subspec|MARC::Spec::Subspec>.
Inherited from L<MARC::Spec::Structure|MARC::Spec::Structure>.
=head2 to_string
Returns the spec as a string.
Inherited from L<MARC::Spec::Structure|MARC::Spec::Structure>.
=head1 PREDICATES
Some predicates are inherited from L<MARC::Spec::Structure|MARC::Spec::Structure>.
=head2 has_char_start
True if attribute char_start has an value and false otherwise.
=head2 has_char_end
True if attribute char_end has an value and false otherwise.
=head2 has_char_pos
True if attribute char_pos has an value and false otherwise.
=head2 has_subspecs
Returns true if attribute subspecs has an value and false otherwise.
=head1 ATTRIBUTES
Some attributes are inherited from L<MARC::Spec::Structure|MARC::Spec::Structure>.
=head2 base
Obligatory. The base Subfield spec without subspecs.
=head2 code
Obligatory. The subfield code.
=head2 char_pos
If defined, the character position or range. Only present if MARC::Spec::Subfield::$char_start is defined.
=head2 char_start
If defined, the beginning character position of a character position or range.
=head2 char_end
If defined, the ending character position of a character position or range.
Only present if MARC::Spec::Subfield::$char_start is defined.
=head2 char_length
The difference of MARC::Spec::Subfield::$char_start and MARC::Spec::Field::$char_end if both are numeric
(or else -1).
Only present if MARC::Spec::Subfield::$char_start is defined.
=head2 index_start
Obligatory. The beginning index of subfield repetitions. Maybe a positiv integer or the character '#'.
Default is 0.
=head2 index_end
Obligatory. The ending index of subfield repetitions. Maybe a positiv integer or the character '#'.
Default is '#'.
=head2 index_length
Obligatory. The difference of MARC::Spec::Subfield::$index_start and MARC::Spec::Subfield::$index_end if both are numeric.
Default is -1.
=head2 subspecs
Optional an array of instances of L<MARC::Spec::Subspec|MARC::Spec::Subspec>, thus all subspecs in this
array MUST be validated as a combination with the boolean 'AND',
and/or an array of arrays (AoA) of instances of L<MARC::Spec::Subspec|MARC::Spec::Subspec>, thus all subspecs
in this AoA must be validated as a combination with the boolean 'OR'.
See L<MARC::Spec::Subspec|MARC::Spec::Subspec> for description of attributes of L<MARC::Spec::Subspec|MARC::Spec::Subspec>.
