Class TransformingCollection<InternalV,ExternalV>

java.lang.Object

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

All Implemented Interfaces:

java.lang.Iterable<ExternalV>, java.util.Collection<ExternalV>

Direct Known Subclasses:

TransformingSet

public class TransformingCollection<InternalV,ExternalV>
extends java.lang.Object
implements java.util.Collection<ExternalV>

A TransformingCollection applies "just in time" transformations to a Collection<InternalV> in order to make it like a Collection<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 TransformingCollection.
