 * Checked exception for Java-style handling of error codes from Patchfield. The {@link Patchfield}
 * class itself doesn't throw exceptions but returns C-style error codes because exceptions can't be
 * thrown via AIDL. If, however, you prefer to use exceptions in Java, you can convert error codes
 * by wrapping calls to Patchfield in the throwOnError method below.
