WriteChannel (Google Cloud Core Parent 2.23.0 API)

All Superinterfaces:

AutoCloseable, Channel, Closeable, Restorable<WriteChannel>, WritableByteChannel

All Known Implementing Classes:

BaseWriteChannel
```
public interface WriteChannel
extends WritableByteChannel, Closeable, Restorable<WriteChannel>
```
A channel for writing data to Google Cloud services.
Implementations of this class may further buffer data internally to reduce remote calls. Written data might not be visible until calling Channel.close(). This interface implements Restorable to allow saving the writer's state to continue writing afterwards.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`RestorableState<WriteChannel>`	`capture()`	Captures the write channel state so that it can be saved and restored afterwards.
`void`	`setChunkSize(int chunkSize)`	Sets the minimum size that will be written by a single RPC.

- Method Detail
  - setChunkSize
```
void setChunkSize(int chunkSize)
```
    Sets the minimum size that will be written by a single RPC. Written data will be buffered and only flushed upon reaching this size or closing the channel.
  - capture
```
RestorableState<WriteChannel> capture()
```
    Captures the write channel state so that it can be saved and restored afterwards. The original WriteChannel and the restored one should not both be used. Closing one channel causes the other channel to close; subsequent writes will fail.
    
    Specified by:
    
    capture in interface Restorable<WriteChannel>
    
    Returns:
    
    a RestorableState object that contains the write channel state and can restore it afterwards.
