Class ObjectArrayTupleMaker

java.lang.Object

com.streambase.sb.unittest.AbstractTupleMaker<java.lang.Object[]>

com.streambase.sb.unittest.ObjectArrayTupleMaker

All Implemented Interfaces:

TupleMaker<java.lang.Object[]>

public class ObjectArrayTupleMaker
extends AbstractTupleMaker<java.lang.Object[]>

A factory to build Tuples from Java objects. Accepts the same objects as Tuple.setField(com.streambase.sb.Schema.Field, Object).

Note that when passing Tuples as value objects to an Enqueuer or Dequeuer, you may obtain the stream's schema from Enqueuer.getSchema() and Dequeuer.getSchema()

For example, given a schema:

  id int,
  name string,
  values list(int),
  listofvalues list(list(int)),
  location tuple(zipcode int, state string),
  prevlocation tuple(zipcode int, state string) 
 

a valid invocation of ObjectArrayTupleMaker.createTuple(Schema, Object[]) might look like:

  createTuple(schema, new Object[] { 1,
                                     "item1",
                                     Arrays.asList(10,20),
                                     "[\"[30,40]\",\"[50,60]\"]",
                                     "2421, MA",
                                     s.getField(5).getSchema().createTuple("10036", "NY")
 });
