Method Detail

getObjectMetadata

public S3ObjectMetadata getObjectMetadata()

Gets the metadata stored by Amazon S3 for this object. The S3ObjectMetadata object includes any custom user metadata supplied by the caller when the object was uploaded, as well as HTTP metadata such as content length and content type.

Returns:

The metadata stored by Amazon S3 for this object.

See Also:

getObjectContent()

setObjectMetadata

public void setObjectMetadata(S3ObjectMetadata metadata)

Sets the object metadata for this object.

NOTE: This does not update the object metadata stored in Amazon S3, but only updates this object in local memory. To update an object's metadata in S3, use org.mule.module.s3.S3Connector#copyObject(String, String, String, String, String, CannedAccessControlList, StorageClass, Map, Date, Date, String) to copy the object to a new (or the same location) and specify new object metadata then.

Parameters:

metadata - The new metadata to set for this object in memory.

getObjectContent

public com.amazonaws.services.s3.model.S3ObjectInputStream getObjectContent()

Gets the input stream containing the contents of this object.

Note: The method is a simple getter and does not actually create a stream. If you retrieve an S3Object, you should close this input stream as soon as possible, because the object contents aren't buffered in memory and stream directly from Amazon S3. Further, failure to close this stream can cause the request pool to become blocked.

Returns:

An input stream containing the contents of this object.

See Also:

getObjectMetadata(), setObjectContent(S3ObjectInputStream)

setObjectContent

public void setObjectContent(com.amazonaws.services.s3.model.S3ObjectInputStream objectContent)

Sets the input stream containing this object's contents.

Parameters:

objectContent - The input stream containing this object's contents.

See Also:

getObjectContent()

getBucketName

public String getBucketName()

Gets the name of the bucket in which this object is contained.

Returns:

The name of the bucket in which this object is contained.

See Also:

setBucketName

public void setBucketName(String bucketName)

Parameters:

isRequesterCharged

public boolean isRequesterCharged()

Returns true if the user is charged for downloading the object from an Requester Pays Bucket; else false.

Returns:

true if the user has been charged for the download operation from Requester Pays Bucket.

setRequesterCharged

public void setRequesterCharged(boolean isRequesterCharged)

Used for downloading an Amazon S3 Object from a Requester Pays Bucket. If set the requester is charged for downloading the data from the bucket.
