Class ColumnFamilyUpdater<K,N>

java.lang.Object
  me.prettyprint.cassandra.service.template.AbstractTemplateUpdater<K,N>
      me.prettyprint.cassandra.service.template.ColumnFamilyUpdater<K,N>

Type Parameters:

K - the key's data type

N - the standard or super column's data type

public class ColumnFamilyUpdater<K,N>
extends AbstractTemplateUpdater<K,N>

This provides an interface of updating a specified row, most likely with the contents of an object. This would likely by implemented as an anonymous inner class with access to a final object in scope. It would update the given row with the object's data. For more complex behaviour, subclasses should implementat update() to simply make consecutive calls to various set****() methods which already have the contextual information they need to update the correct row. The downside of this approach is that the updater is essentially stateful and cannot be used concurrently. The alternative is to pass an object in to update() as a parameter with the setter methods, leaving the updater to be stateless.
