Class PredicateFilterDecoratingClosableIterator<T>

java.lang.Object

picard.vcf.processor.util.PredicateFilterDecoratingClosableIterator<T>

All Implemented Interfaces:

CloseableIterator<T>, Closeable, AutoCloseable, Iterator<T>

public class PredicateFilterDecoratingClosableIterator<T>
extends Object
implements CloseableIterator<T>

Performs on-the-fly filtering of the provided VariantContext Iterator such that only variants that satisfy all predicates are emitted. This class only exists because Iterators.filter(Iterator, Predicate) won't produce a CloseableIterator, which is necessary.
