java.lang.Object
com.streambase.liveview.client.HashableTuple
All Implemented Interfaces:
KeyValue
public abstract class HashableTuple extends Object implements KeyValue
HashableTuple is a wrapper for Tuples from a single Query so they can be stored in a HashSet. If the two wrapped Tuples have the same values for the Query's key fields, then the HashableTuples will have the same hashCode and will return true from .equals()

    • getValueAsUniqueString

      public abstract String getValueAsUniqueString()
      Description copied from interface: KeyValue
      Returns an opaque unique String that can be used to identify this tuple. What this String looks like may change from release to release so should not be persisted.
      Specified by:
