DESCRIPTION

AWS::S3::File provides a convenience wrapper for dealing with files stored in S3.

PUBLIC PROPERTIES

bucket

AWS::S3::Bucket - read-only.

The AWS::S3::Bucket that contains the file.

key

String - read-only.

The 'filename' (for all intents and purposes) of the file.

size

Integer - read-only.

The size in bytes of the file.

etag

String - read-only.

The Amazon S3 'ETag' header for the file.

owner

ASW::S3::Owner - read-only.

The ASW::S3::Owner that the file belongs to.

storage_class

String - read-only.

The type of storage used by the file.

lastmodified

String - read-only.

A date in this format:

            

              
              
2009-10-28T22:32:00
            
          

contents

ScalarRef|CodeRef - read-write.

Returns a scalar-reference of the file's contents.

Accepts either a scalar-ref or a code-ref (which would return a scalar-ref).

Once given a new value, the file is instantly updated on Amazon S3.

            

              
              
# GOOD: (uses scalarrefs)
my $value = "A string";
$file->contents( \$value );
$file->contents( sub { return \$value } );
# BAD: (not scalarrefs)
$file->contents( $value );
$file->contents( sub { return $value } );
            
          

PUBLIC METHODS

delete()

Deletes the file from Amazon S3.

update()

Update contents and/or contenttype of the file.

signed_url( $expiry_time )

Will return a signed URL for public access to the file. $expiry_time should be a Unix seconds since epoch, and will default to now + 1 hour is not passed.

Note that the Signature parameter value will be URI encoded to prevent reserved characters (+, =, etc) causing a bad request.
