Method Detail

copyStreams

public final int copyStreams(InputStream in,
              OutputStream out,
              long sizeLimit)
                      throws IOException

Copy of the the Spring FileCopyUtils, but does not silently absorb IOExceptions when the streams are closed. We require the stream write to happen successfully.

Both streams are closed but any IOExceptions are thrown

Parameters:

in - the stream from which to read content.

out - the stream to which to write content.

sizeLimit - the maximum number of bytes that will be copied between the streams before a ContentLimitViolationException will be thrown. A negative number or zero will be deemed to mean 'no limit'.

Throws:

IOException

copyStreamsLong

public final long copyStreamsLong(InputStream in,
                   OutputStream out,
                   long sizeLimit)
                           throws IOException

Throws:

IOException
