BucketIdFactory (document 7.452.11 API)

java.lang.Object
- com.yahoo.document.BucketIdFactory

```
public class BucketIdFactory
extends java.lang.Object
```
A bucket id contains bit used for various purposes. In most use cases, these can use the default settings, but the number of bits used for the different purposes is configurable, to allow for special uses. Because of this, bucket ids cannot be generated without knowing how the bucket id is configured to be put together, so all bucket ids must be generated by this factory class. For more information about what the sub parts of a bucket id actually is, read the bucket splitting documentation.
