C# Класс BrightIdeasSoftware.FilterMenuBuilder

Instances of this class know how to build a Filter menu. It is responsible for clustering the values in the target column, build a menu that shows those clusters, and then constructing a filter that will enact the users choices.
Almost all of the methods in this class are declared as "virtual protected" so that subclasses can provide alternative behaviours.

Do the work of making a menu that shows the clusters to the users
EnactFilter ( BrightIdeasSoftware.ToolStripCheckedListBox checkedList, OLVColumn column ) : void

Apply the selected values from the given list as a filter on the given column
HandleItemChecked ( object sender, System.Windows.Forms.ItemCheckEventArgs e ) : void

Handle a user-generated ItemCheck event
HandleSelectAllItem ( System.Windows.Forms.ItemCheckEventArgs e, BrightIdeasSoftware.ToolStripCheckedListBox checkedList, int selectAllIndex ) : void

Handle any checking/unchecking of the Select All option, and keep its checkedness in sync with everything else that is checked.
SortClusters ( IClusteringStrategy strategy, List clusters ) : void

Приватные методы

Метод Описание
ClusterOneModel ( IClusteringStrategy strategy, ICluster>.NullableDictionary map, object model ) : void
HandleItemCheckedWrapped ( object sender, System.Windows.Forms.ItemCheckEventArgs e ) : void

Wrap a protected section around the real HandleItemChecked method, so that if that method tries to change a "checkedness" of an item, we don't get a recursive stack error. Effectively, this ensure that HandleItemChecked is only called in response to a user action.
