Interface StatefulMappingFunction<F extends Item,T extends Item>

All Known Implementing Classes:

ForExpression.MappingAction

public interface StatefulMappingFunction<F extends Item,T extends Item>

MappingFunction is an interface that must be satisfied by an object passed to a MappingIterator. StatefulMappingFunction is a sub-interface representing a mapping function that maintains state information, and which must therefore be cloned when the mapping iterator is cloned.
