Create a new MIME::Types
object which manages the data. In the current
implementation, it does not matter whether you create this object often
within your program, but in the future this may change.

Returns a list of all defined extensions.
Returns a list of all defined mime-types by name only. This will not instantiate MIME::Type objects. See types()
Returns the MIME::Type
object which belongs to the FILENAME (or simply
its filename extension) or undef
if the file type is unknown. The extension
is used and considered case-insensitive.
In some cases, more than one type is known for a certain filename extension. In that case, the preferred one is taken (for an unclear definition of preference)
my $types = MIME::Types->new; my $mime = $types->mimeTypeOf('gif'); my $mime = $types->mimeTypeOf('picture.jpg'); print $mime->isBinary;
Returns the MIME::Type
which describes the type related to STRING.
[2.00] Only one type will be returned.
[before 2.00] One type may be described more than once. Different
extensions may be in use for this type, and different operating systems
may cause more than one MIME::Type
object to be defined. In scalar
context, only the first is returned.
Returns a list of all defined mime-types. For reasons of backwards compatibility, this will instantiate MIME::Type objects, which will be returned. See listTypes().
[2.07] Decompose a typical HTTP-Accept header, and sort it based on the included priority information. Returned is a sorted list of type names, where the highest priority type is first. The list may contain '*/*' (accept any) or a '*' as subtype.
Ill-formated typenames are ignored. On equal qualities, the order is kept. See RFC2616 section 14.1
my @types = $types->httpAccept('text/html, application/json;q=0.9');
[2.07] The $accept
string is processed via httpAccept() to order the
types on preference. You may also provide a list of ordered @types
which may have been the result of that method, called earlier.
As second parameter, you pass a LIST of types you @have
to offer.
Those need to be MIME::Type objects. The preferred type will get
selected. When none of these are accepted by the client, this will
return undef
. It should result in a 406 server response.
my $accept = $req->header('Accept'); my @have = map $mt->type($_), qw[text/plain text/html]; my @ext = $mt->httpAcceptBest($accept, @have);
[2.07] Like httpAcceptBest(), but now we do not return a pair with mime-type
and filename, not just the type. If $accept is undef
, the first
filename is returned.
