Class SettingCollector<T>

java.lang.Object

org.cloudgraph.hbase.mutation.SettingCollector<T>

public class SettingCollector<T>
extends Object

Collects old value (settings) for a given data type and property. As an entire history of modifications is sent from the client, for each property modification, collect a unique set of values to get a single collection of original values set to the client. Use this set to compare against actual values in a data store.

Note: the client edge collection can be the results from a slice query where not all the collection results are returned.

Below is an example (in XML representation) of a modification where the property was changed more than once as a result of multiple delete operations.

 
     
     <\modified>
   
     
     <\deleted>
   
     
     <\deleted>
