Field Summary | |
---|---|
protected S |
sourceObject
The source object. |
protected T |
targetObject
The target object. |
Constructor Summary | |
---|---|
Object2ObjectMapping(S source,
T target)
Creates the mapping. |
Method Summary | |
---|---|
void |
clear()
Removes the references of the mapped objects of the mapping to avoid memory leaks. |
S |
getSource()
Returns the source object of the mapping. |
T |
getTarget()
Returns the target object of the mapping. |
void |
init()
At start, the mapping must be executed one time to initialise the binding between source and target objects. |
void |
onListCleaned(java.lang.Object list)
Executes the mapping when all the elements of the source were removed. |
void |
onObjectAdded(java.lang.Object list,
java.lang.Object object,
int index)
Executes the mapping for the addition of an object. |
void |
onObjectMoved(java.lang.Object list,
java.lang.Object object,
int srcIndex,
int targetIndex)
Executes the mapping for the move of an object. |
void |
onObjectRemoved(java.lang.Object list,
java.lang.Object object,
int index)
Executes the mapping for the deletion of an object. |
void |
onObjectReplaced(IUnary<?> object,
java.lang.Object replacedObject)
Executes the mapping when an object has been replaced by an other one. |
