Field Summary | |
---|---|
protected IUnary<S> |
sourceObject
The source unary relation of the mapping. |
protected IUnary<T> |
targetObject
The target unary relation of the mapping. |
Constructor Summary | |
---|---|
Unary2UnaryMapping(IUnary<S> source,
IUnary<T> target)
Creates a unary relation to unary relation mapping. |
Method Summary | |
---|---|
void |
clear()
Removes the references of the mapped objects of the mapping to avoid memory leaks. |
java.lang.Object |
getSource()
Returns the source object of the mapping. |
java.lang.Object |
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. |
