```
public final class LazyBooleanIterate
extends Object
```
LazyBooleanIterate is a factory class which creates "deferred" boolean iterables around the specified boolean iterables. A "deferred" boolean iterable performs some operation, such as filtering or transforming, when the result boolean iterable is iterated over. This makes the operation very memory efficient, because you don't have to create intermediate collections during the operation.
