Method Detail

copy

public static long copy(InputStream input,
                        OutputStream output)
                 throws IOException

Copy bytes from a large (over 2GB) InputStream to an OutputStream.

This method is based on an implementation from Apache Commons-IO

Parameters:

input - the InputStream to read from

output - the OutputStream to write to

Returns:

the number of bytes copied

Throws:

NullPointerException - if the input or output is null

IOException - if an I/O error occurs

copyWhileDataAvailable

public static long copyWhileDataAvailable(InputStream input,
                                          OutputStream output)
                                   throws IOException

Throws:

IOException

deleteAllFromDirectory

public static void deleteAllFromDirectory(File theWorkfilesDir)

deleteAllFromDirectoryExcept

public static void deleteAllFromDirectoryExcept(File theDirectory,
                                                List<File> theExcept)
                                         throws IOException

Throws:

IOException

readClasspathIntoByteArray

public static byte[] readClasspathIntoByteArray(String theString)
                                         throws IOException

Read a classpath resource into a byte array

Throws:

IOException

readInputStreamIntoByteArraWhileDataAvailable

public static byte[] readInputStreamIntoByteArraWhileDataAvailable(InputStream res)
                                                            throws IOException

Throws:

IOException

readInputStreamIntoByteArray

public static byte[] readInputStreamIntoByteArray(InputStream res)
                                           throws IOException

Read an entire input stream into a byte array

Throws:

IOException
