> Key: CAMEL-262
> URL: https://issues.apache.org/activemq/browse/CAMEL-262

> I have used structure101 on camel and found some design tangles that are
> quite easy to resolve.
> The first is in impl. Defaultcomponent contains a special case to handle
> ScheduledPollEndpoint. As they reference each other there is a dependency
> tangle. I have attached a screenshot from struture101 with current and
> suggested status.
> This is the current code:
> if (endpoint instanceof ScheduledPollEndpoint) {
> ScheduledPollEndpoint scheduledPollEndpoint =
> (ScheduledPollEndpoint)endpoint;
> scheduledPollEndpoint.configureProperties(parameters);
> }
> My suggestion is to add configureProperties to Endpoint and DefaultEndpoint.
> So any endpoint offers this useful method. The code is then simpler and the
> tangle is resolved:
> endpoint.configureProperties(parameters);
> The second tangle is in components file. The package file and strategy
> reference each other heavily. I have attached screenshots of the tangle.
> This is because The strategies are configured directly in Endpoint (package
> file). My suggestion is to create a factory inside the package strategy. So
> there is only on dependency from file to strategy. Another reason is that
> the FileProcessStrategy interface is in the strategy package. I think this
> interface belongs to the package file. Using these two changes I managed to
> reduce the dependencies between strategy and file from 12/17 to 8/1. This
> makes the code much easier to grasp as you can understand the packages
> separately.
> I have attached a patch and screenshots for both issues.
> What do you think?
