When using RowsFragment, does ObjectAdapter.setPresenterSelector do anything?

Question

I'm using RowsFragment with an ObjectAdapter and I spotted the method ObjectAdapter.setPresenterSelector. However, I've already set my PresenterSelector using RowsFragment.setPresenterSelector, so I'm not sure what ObjectAdapter.setPresenterSelector does. Does it do anything?

Answer 1

Ok, I looked into it and the answer is in the source code of ItemBridgeAdapter. The method to look up item type contains the following line:

PresenterSelector presenterSelector = mPresenterSelector != null ? mPresenterSelector : mAdapter.getPresenterSelector();

where mPresenterSelector is the thing set by RowsFragment.setPresenterSelector and mAdapter is the the ObjectAdapter. So it looks like they first look at what you called RowsFragment.setPresenterSelector with, and if that's null, they then try to use the ObjectAdapter's PresenterSelector.
