ProgressInputStream

public ProgressInputStream(InputStream is,
                   ProgressListener listener)

ProgressInputStream

public ProgressInputStream(InputStream is,
                   ProgressListener listener,
                   int notifyThresHold)

方法详细资料

inputStreamForRequest

public static InputStream inputStreamForRequest(InputStream is,
                                ProgressListener progressListener)

参数:

is - the request content input stream

progressListener - Optional progress listener

返回:

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,
                                 CosServiceRequest 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.

参数:

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.

参数:

is - the response content input stream

progressListener - Optional progress listener

返回:

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.

onFirstRead

protected void onFirstRead()

The read method is called for the very first time. Defaults to do nothing.

onEOF

protected void onEOF()

An end-of-file event is to be notified. Defaults to do nothing.

onClose

protected void onClose()

Defaults to behave the same as onEOF().

onReset

protected void onReset()

A reset event is to be notified. Default to do nothing.

onNotifyBytesRead

protected void onNotifyBytesRead()

Upon notification of the number of bytes transferred since last notification. Default to do nothing.

指定者:

close 在接口中 Closeable

指定者:

close 在接口中 AutoCloseable

覆盖:

close 在类中 SdkFilterInputStream

抛出:

IOException
