Class FilterIterator<T>

java.lang.Object
com.github.basking2.sdsai.itrex.iterators.FilterIterator<T>
Type Parameters:
T - The element type to filter.
All Implemented Interfaces:
Iterator<T>
public class FilterIterator<T> extends Object implements Iterator<T>
Similar to the NullSkippingIterator, this will skip values if they fail a provided check. Skipping is done by prefetching 1 element to ensure we can accurately compute hasNext().
