Method Details

saveBytes

public static void saveBytes(File file,
 byte[] bytes)
                      throws IOException

Saves the contents of a byte[] to the specified File.

Throws:

IOException

readBytes

public static byte[] readBytes(File file)
                        throws IOException

Reads the contents of a File into a byte[]. This relies upon File.length() returning the correct value, which may not be the case when using a network file system. However this method is intended for unit test support, in which case the files should be on the local volume.

Throws:

IOException

public static byte[] readBytes(String filePath)
                        throws IOException

Reads the contents of a File into a byte[]. This relies upon File.length() returning the correct value, which may not be the case when using a network file system. However this method is intended for unit test support, in which case the files should be on the local volume.
