Interface ConditionalStoreMutation<T>

All Superinterfaces:

Mutation<T>

public interface ConditionalStoreMutation<T>
extends Mutation<T>

Extends Mutation and allows for a store operation not to occur if the object it is being applied to is not modified.

By implementing this interface you can avoid a store operation from occurring if the object it is be applied to is not modified.

For example:

 Mutation<IRiakObject> m = new ConditionalStoreMutation<IRiakObject>() {
     private boolean modified;
 
     @Override
     IRiakObject apply(IRiakObject original) {
          // I didn't do anything!
          modifed = false; 
     }
 
     @Overrive
     boolean hasMutated() {
         return modified;
     }
 };
