Add a new Extension.initialize function for doing initialization.
Review Request #5316 — Created Jan. 24, 2014 and submitted
Previously, custom extensions would subclass
__init__, take the required
arguments, call the parent function, and perform initialization. In
order to simplify this a bit, extensions can now choose to override
initialize()instead, which will be called by
This function does nothing by default, and does not need to be called by
the subclass. That simplifies extensions, saving some code.
Modified an extension locally. It initialized correctly.
