Mail::Field is extended by Mail::Field::AddrList Mail::Field::Date Mail::Field::Generic
use Mail::Field; my $field = Mail::Field->new('Subject', 'some subject text'); my $field = Mail::Field->new(Subject => 'some subject text'); print $field->tag,": ",$field->stringify,"\n"; my $field = Mail::Field->subject('some subject text');
"Mail::Field"creates and manipulates fields in MIME headers, collected within a Mail::Header object. Different field types have their own sub-class (extension), defining additional useful accessors to the field content.
Mail::Field (and it's sub-classes) define several methods which return new objects. These can all be categorized as constructor.
"Mail::Field"objects (which should all be of the same sub-class) and create a new object in that same class.:
"Mail::Head"object and optionally an index.
"extract"will retrieve the given tag from the
"Mail::Head"object and create a new
"Mail::Field"based object. undef will be returned in the field does not exist. If the index argument is not given the result depends on the context in which
"extract"is called. If called in a scalar context the result will be as if
"extract"was called with an index value of zero. If called in an array context then all tags will be retrieved and a list of
"Mail::Field"objects will be returned.
It is more clear to call either stringify() or parse() directly, because this method does not add additional processing.
All sub-classes should be called Mail::Field::name where name is derived from the tag using these rules.
