Josh Wills created CRUNCH-157:
---------------------------------
Summary: Mark the setContext function in the DoFn class as final
Key: CRUNCH-157
URL: https://issues.apache.org/jira/browse/CRUNCH-157
Project: Crunch
Issue Type: Improvement
Components: Core
Affects Versions: 0.4.0, 0.3.0
Reporter: Josh Wills
Assignee: Josh Wills
We often use a pattern of nested DoFns-- DoFns that are composed of operations
on other DoFns. There is currently an ambiguity around the right way to
initialize those DoFns, since it can be done either via overriding the
initialize() or the setContext() methods in DoFn. We should mark setContext as
final in order to remove the ambiguity and fix the instances in Crunch core
where we override setContext() instead of initialize().
