Examples of Joiner

cascading.pipe.joiner.Joiner
Interface Joiner allows for custom join strategies against a {@link cascading.pipe.CoGroup}.
Joins perform based on the equality of the join keys. In the case of null values, Java treats two null values as equivalent. SQL does not treat null values as equal. To produce SQL like results in a given join, a new {@link java.util.Comparator} will need to be used on the joined values to prevent null fromequaling null. As a convenience, see the {@link cascading.util.NullNotEquivalentComparator} class.
