Method Detail

cleanup

public static void cleanup(Closeable... closeables)

Closes the Closeable objects and ignore any IOException or null pointers. Must only be used for cleanup in exception handlers.

Parameters:

closeables - the objects to close.

closeQuietly

public static void closeQuietly(Closeable closeable)

Closes the given Closeable quietly by ignoring IOException.

Parameters:

closeable - The resource to close.

1.1.0

readFully

public static void readFully(Input in,
                             long position,
                             byte[] buffer,
                             int offset,
                             int length)
                      throws IOException

Does the readFully based on Input's positioned read. This does not change the current offset of the stream and is thread-safe.

Parameters:

in - the input source.

position - the given position.

buffer - the buffer to be read.

length - the maximum number of bytes to read.

offset - the start offset in array buffer.

Throws:

IOException - if an I/O error occurs.

readFully

public static void readFully(InputStream in,
                             byte[] buf,
                             int off,
                             int len)
                      throws IOException

Does the readFully based on the Input read.

Parameters:

in - the input stream of bytes.

buf - the buffer to be read.

off - the start offset in array buffer.

len - the maximum number of bytes to read.

Throws:

IOException - if an I/O error occurs.
