Re: [Scaffoldhunter-devel] Table View

[Till S. <til...@tu...>]

Hi, 
sorry for the late answer. Some of us had a deadline on Monday, which distracted us a bit from answering questions. 

To understand the current behavior of the table sorting i have to explain lazy loading of properties first:

To avoid unnecessary memory consumption we are not holding all properties of all molecules in memory. Only the needed properties are loaded on demand (this done by DbManager.lockAndLoad and DbManager.unlockAndUnload). Sorting the Table would therefore require to load the sort-property completely (for all molecules of the current subset) into the ram. As this is still not very efficient. We have a DbManager method getSortOrder, that calculates the sort order on the database level and returns this sort order only. 

You can start with the TableViewRowSorter class as an entry point. Please note, that the table view does not use a very clean code structure. This is the darker side of SH regarding  the code quality ;-) . 

Greetings 
Till
