Class TransformingIterator<InternalV,ExternalV>

java.lang.Object

com.electronwill.nightconfig.core.utils.TransformingIterator<InternalV,ExternalV>

All Implemented Interfaces:

Iterator<ExternalV>

Direct Known Subclasses:

TransformingListIterator

public class TransformingIterator<InternalV,ExternalV>
extends Object
implements Iterator<ExternalV>

A TransformingIterator applies "just in time" transformations to an Interator<InternalV> in order to make it like an Interator<ExternalV>.

The transformations are applied "just in time", that is, the values are converted only when they are used, not during the construction of the TransformingIterator.
