copyStream

public static boolean copyStream(InputStream is,
                                 OutputStream os,
                                 IoUtils.CopyListener listener)
                          throws IOException

Copies stream, fires progress events by listener, can be interrupted by listener. Uses buffer size = 32768 bytes.

参数:

is - Input stream

os - Output stream

listener - null-ok; Listener of copying progress and controller of copying interrupting

返回:

true - if stream copied successfully; false - if copying was interrupted by listener

抛出:

IOException

copyStream

public static boolean copyStream(InputStream is,
                                 OutputStream os,
                                 IoUtils.CopyListener listener,
                                 int bufferSize)
                          throws IOException

Copies stream, fires progress events by listener, can be interrupted by listener.

参数:

is - Input stream

os - Output stream

listener - null-ok; Listener of copying progress and controller of copying interrupting

bufferSize - Buffer size for copying, also represents a step for firing progress listener callback, i.e. progress event will be fired after every copied bufferSize bytes

返回:

true - if stream copied successfully; false - if copying was interrupted by listener

抛出:

IOException

readAndCloseStream

public static void readAndCloseStream(InputStream is)

Reads all data from stream and close it silently

参数:

is - Input stream

closeSilently

public static void closeSilently(Closeable closeable)
