Class LazyDoubleIterate

java.lang.Object

org.eclipse.collections.impl.utility.primitive.LazyDoubleIterate

public final class LazyDoubleIterate
extends Object

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