Method Detail

copyStream

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

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

Parameters:

is - Input stream

os - Output stream

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

Returns:

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

Throws:

java.io.IOException

copyStream

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

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

Parameters:

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

Returns:

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

Throws:

java.io.IOException

readAndCloseStream

public static void readAndCloseStream(java.io.InputStream is)

Reads all data from stream and close it silently

Parameters:

is - Input stream

closeSilently

public static void closeSilently(java.io.Closeable closeable)
