Package com.electronwill.nightconfig.core.utils

Class TransformingSpliterator<InternalV,ExternalV>

java.lang.Object

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

All Implemented Interfaces:

java.util.Spliterator<ExternalV>

public final class TransformingSpliterator<InternalV,ExternalV>
extends java.lang.Object
implements java.util.Spliterator<ExternalV>

A TransformingSpliterator applies "just in time" transformations to an Spliterator<InternalV> in order to make it like an Spliterator<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 TransformingSpliterator.
