public static void saveBytes(java.io.File file,
                             byte[] bytes)
                      throws java.io.IOException
```
    Saves the contents of a byte[] to the specified File.
    
    Throws:
    
    java.io.IOException
  - readBytes
```
public static byte[] readBytes(java.io.File file)
                        throws java.io.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:
    
    java.io.IOException
  - readBytes
```
public static byte[] readBytes(java.lang.String filePath)
