- Method Detail
  - getAllFields
```
public static java.util.Map<java.lang.String,java.lang.reflect.Field> getAllFields(java.lang.Class<?> clazz)
```
    Lists all instance fields on an object, including non-public and inherited fields.
  - getFieldValues
```
public static java.util.Map<java.lang.reflect.Field,java.lang.Object> getFieldValues(java.lang.Object instance)
```
    Returns a map from Field objects (including non-public and inherited fields) to values.
    This turns arrays into List objects so that ImmutableObject can more easily use the returned map in its implementation of ImmutableObject.toString() and ImmutableObject.equals(java.lang.Object), which work by comparing and printing these maps.
  - cloneEmptyToNull
```
protected static <T extends ImmutableObject> T cloneEmptyToNull(T obj)
```
    Returns a clone of the object and sets empty collections, arrays, maps and strings to null.
