Class PutObjectRequest

java.lang.Object
  extended by com.amazonaws.AmazonWebServiceRequest
      extended by com.amazonaws.services.s3.model.PutObjectRequest

public class PutObjectRequest
extends AmazonWebServiceRequest

Uploads a new object along with optional object metadata to Amazon S3 under the specified bucket and key name and optionally applies a canned access control policy to the new object.

Amazon S3 never stores partial objects: if you don't receive an exception, then you can be confident that the entire object was stored.

A checksum of the uploaded data is automatically computed on the client and verified against another checksum calculated when the data reaches Amazon S3 to ensure that the data does not get corrupted over the network.

If a file is specified (instead of an InputStream), the filename will be used to try and automatically determine the correct content type to use for the object, unless the specified object metadata explicitly declares a content type. Content disposition will also be automatically set when uploading directly from a file.

If versioning is enabled for the specified bucket, this operation will never overwrite an existing object at the same key, but instead will keep the existing object around as an older version until that version is explicitly deleted (see AmazonS3.deleteVersion(DeleteVersionRequest)).

If versioning is suspended or off, uploading an object to an existing key will overwrite any existing object stored under that key because Amazon S3 stores the last write request. However, Amazon S3 is a distributed system. If Amazon S3 receives multiple write requests for the same object nearly simultaneously, all of the objects might be stored, even though only one wins in the end. Amazon S3 does not provide object locking; if you need this, make sure to build it into your application layer.

If you specify a location constraint when creating a bucket, all objects added to the bucket are stored in the bucket's location. For example, if you specify a region in Europe (EU) constraint for a bucket, all of that bucket's objects are stored in EU.

The specified bucket must already exist and you must have Permission.Write permission to the bucket to upload an object.

Constructor Detail

PutObjectRequest

public PutObjectRequest(String bucketName,
                        String key,
                        File file)
Constructs a new PutObjectRequest object to upload a file to the specified bucket and key. After constructing the request, you can optionally specify object metadata or a canned ACL as well.

Parameters:
bucketName - The name of an existing bucket to which the new object will be uploaded.
key - The key under which to store the new object.
file - The file to upload to Amazon S3.

PutObjectRequest

public PutObjectRequest(String bucketName,
                        String key,
                        InputStream input,
                        ObjectMetadata metadata)
Constructs a new PutObjectRequest object to upload a stream of data to the specified bucket and key. After constructing the request, you can optionally specify a canned ACL as well.

Content length for the stream of data being uploaded must be specified in the object metadata parameter, since Amazon S3 requires it be passed in before the data is uploaded. Failure to specify a content length will cause the entire contents of the input stream to be buffered locally in memory so that the content length can be calculated, which can result in negative performance problems.

Parameters:
bucketName - The name of an existing bucket to which the new object will be uploaded.
key - The key under which to store the new object.
input - The stream of data to upload to Amazon S3.
metadata - The object metadata, which at minimum should specify the content length for the stream of data being uploaded.
