ColumnFilterMapper is used to present users with available filter expressions and to create, apply and remove filters for a FilterTreeTableModel.

The method that is called before filter expressions are made available to the user is:

public void filterVisible(int modelIndex, CheckBoxTree tree, TreeTableModel treeTableModel, TreeTable table);

The above method will prepare the TreeTable accordingly, with values from the given treeTableModel parameter.

Then, if the filter action is commited, the following method is called:

public void commitFilters(FilterTreeTableModel filterTreeTableModel, Filter filter, int modelIndex);

Otherwise, if the filter action is cancelled, the method below is called:

public void filterCancelled();

The stored filters can be applied any time for any FilterTreeTableModel with the method:

public void applyFilters(FilterTreeTableModel filterTreeTableModel, int[] excludedModelIndexes);

They can also be removed with:

public boolean removeFilters(int[] modelIndexes);

Additionally, to determine whether a given column has a filter:

public boolean hasFilter(int modelIndex);
