Method Detail

closeStream

public static void closeStream(Closeable stream)

Closes the stream ignoring IOException. Must only be called in cleaning up from exception handlers.

Parameters:

stream - the Stream to close

closeAll

public static void closeAll(Closeable... closeables)
                     throws IOException

Closes every non-null object, preserving any IOException thrown.

Parameters:

closeables - the objects to close, in order

Throws:

IOException - the first exception thrown while closing, with later exceptions added as suppressed exceptions

closeAll

public static void closeAll(Collection<? extends Closeable> closeables)
                     throws IOException

Closes every non-null object, preserving any IOException thrown.

Parameters:

closeables - the objects to close, in iteration order

Throws:

IOException - the first exception thrown while closing, with later exceptions added as suppressed exceptions

cleanup

public static void cleanup(org.slf4j.Logger log,
                           Closeable... closeables)

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

Parameters:

log - the log to record problems to at debug level. Can be null.

closeables - the objects to close

copyBytes

public static void copyBytes(InputStream in,
                             OutputStream out,
                             int buffSize,
                             boolean close)
                      throws IOException

Copies from one stream to another.

Parameters:

in - InputStrem to read from

out - OutputStream to write to

buffSize - the size of the buffer

close - whether or not close the InputStream and OutputStream at the end. The streams are closed in the finally clause.

Throws:

IOException

copyBytes

public static void copyBytes(InputStream in,
                             OutputStream out,
                             int buffSize)
                      throws IOException

Copies from one stream to another.

Parameters:

in - InputStrem to read from

out - OutputStream to write to

buffSize - the size of the buffer

Throws:

IOException
