DataDistributionByHash (eXo PLF:: JCR :: Component :: Extension Service 6.2.5-RC01 API)

java.lang.Object
- org.exoplatform.services.jcr.ext.distribution.impl.AbstractDataDistributionType
- - org.exoplatform.services.jcr.ext.distribution.impl.DataDistributionByHash

All Implemented Interfaces:

DataDistributionType
```
public class DataDistributionByHash
extends AbstractDataDistributionType
```
It will generate from the data id an hash code thanks to an hashing function then with this hash code it will be able to generate a hierarchy of sub-nodes with n levels of depth for example with n = 4 and MD5 as hashing function: For "john.smith" with MD5, the hash code in base 32 is 12spjkm4fhsrl151pva3f7mf1r, so the path would be "1/2/s/john.smith"
