Constructor Detail

S3ObjectInputStream

public S3ObjectInputStream(InputStream in,
                           org.apache.http.client.methods.HttpRequestBase httpRequest)
Method Detail

abort

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

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.

Throws:
IOException

getHttpRequest

public org.apache.http.client.methods.HttpRequestBase getHttpRequest()
Returns the http request from which this input stream is derived.
