protected abstract void |
cleanup(MatchingFrame frame,

protected abstract boolean |
fillInValue(T newValue,
MatchingFrame frame,
ISearchContext context)
Updates the frame with the next element of the iterator.
|
protected abstract java.util.Iterator<? extends T> |
getIterator(MatchingFrame frame,
ISearchContext context)
Returns an iterator with the possible options from the current state
|
void |
onBacktrack(MatchingFrame frame,
ISearchContext context)
After the execution of the operation failed and
ISearchOperation.ISearchOperationExecutor.execute(MatchingFrame, ISearchContext) returns false, the onBacktrack
callback is evaluated. |
void |
onInitialize(MatchingFrame frame,
ISearchContext context)
During the execution of the corresponding plan, the onInitialize callback is evaluated before the execution of
