10.2 Coerce

The cascading.pipe.assembly.SumBy SubAssembly is used to coerce a set of values from one type to another type - for example, to convert the field age from a String to an Integer.

Example 10.6. Using Coerce

// incoming -> first, last, age

assembly =
  new Coerce( assembly, new Fields( "age" ), Integer.class );

// outgoing -> first, last, age
