Method Detail

inputStreamForRequest

@Deprecated
public static InputStream inputStreamForRequest(InputStream is,
                                                            AmazonWebServiceRequest req)

Deprecated.

Returns an input stream for request progress tracking purposes. If request/response progress tracking is not enabled, this method simply return the given input stream as is.

Parameters:

is - the request content input stream

inputStreamForRequest

public static InputStream inputStreamForRequest(InputStream is,
                                                ProgressListener progressListener)

Parameters:

is - the request content input stream

progressListener - Optional progress listener

Returns:

If the progress listener is non null returns a new input stream decorated with progress reporting functionality. If progress listener is null it returns the same input stream.

inputStreamForResponse

public static InputStream inputStreamForResponse(InputStream is,
                                                 AmazonWebServiceRequest req)

Returns an input stream for response progress tracking purposes. If request/response progress tracking is not enabled, this method simply return the given input stream as is.

Parameters:

is - the response content input stream

inputStreamForResponse

public static InputStream inputStreamForResponse(InputStream is,
                                                 ProgressListener progressListener)

Returns an input stream for response progress tracking purposes. If request/response progress tracking is not enabled, this method simply return the given input stream as is.

Parameters:

is - the response content input stream

progressListener - Optional progress listener

Returns:

If the progress listener is non null returns a new input stream decorated with progress reporting functionality. If progress listener is null it returns the same input stream.
