Class LazyLongIterate

java.lang.Object

org.eclipse.collections.impl.utility.primitive.LazyLongIterate

public final class LazyLongIterate
extends Object

LazyLongIterate is a factory class which creates "deferred" long iterables around the specified long iterables. A "deferred" long iterable performs some operation, such as filtering or transforming, when the result long iterable is iterated over. This makes the operation very memory efficient, because you don't have to create intermediate collections during the operation. This file was automatically generated from template file lazyPrimitiveIterate.stg.
