T - the type of elements held in this collectionpublic class LazyListX<T> extends AbstractFluentCollectionX<T> implements ListX<T>
List
Extended List operations execute lazily e.g.
LazyListX<Integer> q = LazyListX.of(1,2,3)
.map(i->i*2);
The map operation above is not executed immediately. It will only be executed when (if) the data inside the
queue is accessed. This allows lazy operations to be chained and executed more efficiently e.g.
LazyListX<Integer> q = LazyListX.of(1,2,3)
.map(i->i*2);
.filter(i->i<5);
The operation above is more efficient than the equivalent operation with a ListX.AbstractFluentCollectionX.LazyCollection<T,C extends java.util.Collection<T>>, AbstractFluentCollectionX.PersistentLazyCollection<T,C extends java.util.Collection<T>>| Modifier and Type | Method and Description |
