public class S3ObjectInputStream
extends com.amazonaws.internal.SdkFilterInputStream
S3Object
. In addition to
the methods supplied by the InputStream
class,
S3ObjectInputStream
supplies the abort() method, which will terminate
an HTTP connection to the S3 object.in

abort()
Aborts the underlying http request without reading any more data and
closes the stream.

int |
available()
Returns super.available() if the value is not zero or else always returns

public void abort()
By default Apache HttpClient
tries to reuse http connections by
reading to the end of an attached input stream on
InputStream.close()
. This is efficient from a socket pool
management perspective, but for objects with large payloads can incur
significant overhead while bytes are read from s3 and discarded. It's up
to clients to decide when to take the performance hit implicit in not
reusing an http connection in order to not read unnecessary information
from S3.
