Generates a content binding between an javafx.collections.ObservableMap and a java.util.Map.

A content binding ensures that the Map contains the same elements as the ObservableMap. If the content of the ObservableMap changes, the Map will be updated automatically.

Once a Map is bound to an ObservableMap, the Map must not be changed directly anymore. Doing so would lead to unexpected results.

A content-binding can be removed with unbindContent(Object, Object).

Parameters:

<K>		the type of the key elements of the Map
<V>		the type of the value elements of the Map
map1		the Map
map2		the ObservableMap

Exceptions:

NullPointerException		if one of the maps is null
IllegalArgumentException		if map1 == map2
