Class LazyIntIterate

java.lang.Object

org.eclipse.collections.impl.utility.primitive.LazyIntIterate

public final class LazyIntIterate
extends Object

LazyIntIterate is a factory class which creates "deferred" int iterables around the specified int iterables. A "deferred" int iterable performs some operation, such as filtering or transforming, when the result int 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.
