java.lang.Object

org.vishia.util.IterableIndirect<Tsrc,Tdst>

Type Parameters:

Tsrc - Type of the original Iterable

Tdst - Type of the indirect gotten instance

All Implemented Interfaces:

java.lang.Iterable<Tdst>, java.util.Iterator<Tdst>, IterableIterator<Tdst>

public abstract class IterableIndirect<Tsrc,Tdst>
extends java.lang.Object
implements IterableIterator<Tdst>

Iterator which returns an indirect instance because of a given Iterable. The implementor have to override the conv(Object) which converts from the original elements of the iterable to the return instance.
