- htsjdk.samtools.cram.structure.SliceBlocksWriteStreams

```
public class SliceBlocksWriteStreams
extends Object
```
Provides a layer over a SliceBlocks object and acts as a bridge between the DataSeries codecs and their underlying blocks when writing a CRAM stream by presenting a bit (core) or byte (external) stream for each block.

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`SliceBlocks`	`flushStreamsToBlocks()`	Compress and write each each stream to a corresponding Block (note that this does not write the blocks themselves to a container output stream - that can't happen until the slice is aggregated into a container.
`BitOutputStream`	`getCoreOutputStream()`
`ByteArrayOutputStream`	`getExternalOutputStream(Integer contentID)`	Get the ByteArrayOutputStream corresponding to the requested contentID
