visitDefault

public void visitDefault(SelectObjectContentEvent selectEvent)

A required "else" or "default" block, invoked with no other more-specific "visit" method is appropriate. This is invoked under two circumstances:

1. The event encountered is newer than the current version of the SDK, so no other more-specific "visit" method could be called. In this case, the provided event will be a generic SelectObjectContentEvent. These events can be processed by upgrading the SDK.
2. The event is known by the SDK, but the "visit" was not overridden above. In this case, the provided event will be a specific type of SelectObjectContentEvent.

Parameters:

selectEvent - The event that was not handled by a more-specific "visit" method.
