org.apache.calcite.runtime.AbstractImmutableList<T>

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

org.apache.calcite.runtime.FlatLists.Flat3List<T>

Type Parameters:

T - Element type

All Implemented Interfaces:

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

Enclosing class:

FlatLists

protected static class FlatLists.Flat3List<T>
extends FlatLists.AbstractFlatList<T>
implements FlatLists.ComparableList<T>

List that stores its three elements in the three 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, cannot be modified or re-sized. The elements may be null.

The list is created via FlatLists.of(java.util.List).
