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.
