public ProxyMaps()

Method Detail

beforeClear

public static void beforeClear(ProxyMap map)

Call before invoking Map.clear() on super.

keySet

public static Set keySet(ProxyMap map)

Override for Map.keySet().

values

public static Collection values(ProxyMap map)

Override for Map.values().

afterEntrySet

public static Set afterEntrySet(ProxyMap map,
                                Set entries)

Wrap the given entry set in a proxy.

beforeGet

public static boolean beforeGet(ProxyMap map,
                                Object key)

Call before invoking Map.get(java.lang.Object) on super.

afterGet

public static Object afterGet(ProxyMap map,
                              Object key,
                              Object ret,
                              boolean before)

Call after invoking Map.get(java.lang.Object) on super. The potential change is tracked when the get method is called. This change will not translated to an update statement if the retrieved value is not dirty.

Parameters:

ret - the return value from the super's method

before - the return value from beforeGet(org.apache.openjpa.util.ProxyMap, java.lang.Object)

Returns:

the value to return from Map.get(java.lang.Object)

beforePut

public static boolean beforePut(ProxyMap map,
                                Object key,
                                Object value)

Call before invoking Map.put(K, V) on super.

afterPut

public static Object afterPut(ProxyMap map,
                              Object key,
                              Object value,
                              Object ret,
                              boolean before)

Call after invoking Map.put(K, V) on super.

Parameters:

ret - the return value from the super's method

before - the return value from beforePut(org.apache.openjpa.util.ProxyMap, java.lang.Object, java.lang.Object)

Returns:

the value to return from Map.put(K, V)

beforeSetProperty
