Class PredicateFilterDecoratingClosableIterator<T>

java.lang.Object
picard.vcf.processor.util.PredicateFilterDecoratingClosableIterator<T>
All Implemented Interfaces:
htsjdk.samtools.util.CloseableIterator<T>, Closeable, AutoCloseable, Iterator<T>
public class PredicateFilterDecoratingClosableIterator<T> extends Object implements htsjdk.samtools.util.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.
