VariantIteratorProducer (picard 2.18.25 API)

java.lang.Object
- picard.vcf.processor.VariantIteratorProducer

```
public abstract class VariantIteratorProducer
extends Object
```
A mechanism for iterating over CloseableIterator of VariantContexts in in some fashion, given VCF files and optionally an interval list. The produced iterators may perform on-the-fly filtering of the produced VariantContexts.

All Methods Static Methods Instance Methods Abstract Methods Concrete Methods
Modifier and Type	Method	Description
`static VariantIteratorProducer`	`byHundredMegabaseChunks(List<File> vcfs)`	Produces a chunking with segments of size 100 megabases (or less if a contig boundary is reached).
`static VariantIteratorProducer`	`byHundredMegabaseChunksWithOnTheFlyFilteringByInterval(List<File> vcfs, htsjdk.samtools.util.IntervalList intervalList)`	Produces a chunking with segments of size 100 megabases (or less if a contig boundary is reached), that also performs on-the-fly filtering of `VariantContext`
`abstract void`	`close()`	Closes any latent file handles that may have been opened by calls to `iterators()`.
`abstract Iterable<htsjdk.samtools.util.CloseableIterator<htsjdk.variant.variantcontext.VariantContext>>`	`iterators()`	Renders the embodied regions of the VCF files in the form of `CloseableIterator`s over `VariantContext`s.

```
public abstract Iterable<htsjdk.samtools.util.CloseableIterator<htsjdk.variant.variantcontext.VariantContext>> iterators()
```
    Renders the embodied regions of the VCF files in the form of CloseableIterators over VariantContexts. The iterator may perform on-the-fly filtering of these elements.
  - close
```
public abstract void close()
```
    Closes any latent file handles that may have been opened by calls to iterators().
