Class PredicateFilterDecoratingClosableIterator<T>

java.lang.Object

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

All Implemented Interfaces:

htsjdk.samtools.util.CloseableIterator<T>, java.io.Closeable, java.lang.AutoCloseable, java.util.Iterator<T>

public class PredicateFilterDecoratingClosableIterator<T>
extends java.lang.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.
