Class FlatLists.Flat1List<T>

java.lang.Object

org.apache.calcite.runtime.FlatLists.AbstractFlatList<T>

org.apache.calcite.runtime.FlatLists.Flat1List<T>

Type Parameters:

T - Element type

All Implemented Interfaces:

Comparable<List>, Iterable<T>, Collection<T>, List<T>, RandomAccess, FlatLists.ComparableList<T>

Enclosing class:

FlatLists

protected static class FlatLists.Flat1List<T>
extends FlatLists.AbstractFlatList<T>
implements FlatLists.ComparableList<T>

List that stores its one elements in the one members of the class. Unlike ArrayList or Arrays.asList(Object[]) there is no array, only one piece of memory allocated, therefore is very compact and cache and CPU efficient.

The list is read-only and cannot be modified or re-sized. The element may be null.

The list is created via FlatLists.of().
