Implementation code used by the TableSelectionModel implementations. In short this code exists to speed up some common use cases which were incredibly slow in the old approach. The old approach essentially required a lot of iterating through the selectedCells list. The new approach is to keep this list for what it is good for (representing selection order primarily), and introduce a Map to speed up the slow parts - namely looking up whether a given row/column intersection is selected or not. Note that a map that contains an empty bitset is used to represent that the row is selected. Refer to JDK-8123472 for more information on this issue.
