EventContext<T extends DataGridRow> class

Context provided to events for applying state transformations.

Contains only complex/stateful components:

• ViewportDelegate: Pluggable viewport calculations
• SortDelegate: Pluggable sorting with debouncing and async operations
• FilterDelegate: Pluggable filtering with debouncing and async operations
• DataIndexer: Data filtering and sorting operations
