public class IndexQuery

extends java.lang.Object

implements Query

Class IndexQuery Use the T Tree index structure to answer the query. This class extends the generic Query interface. An IndexQuery object is specified at the client and passed to the server in a template tuple. At the server, it is transformed to a TSIndexQuery object that is actually used for the query operation.

Example usage:

     String value1 = "any old data";
     String key1 = "mykey";
     ts.write(new Field("index1",key1),new Field(value1);
   ...
     Field f1 = new Field(new IndexQuery("index1","mykey"));
     Tuple template = new Tuple(f1);
     ts.take(template);
