Interface IGridSortState

All Known Implementing Classes:

GridSortState

public interface IGridSortState

Allows to query the sort state of a grid. Sort state determines by which properties and in what direction the data should be sorted. This interface allows data to be sorted by multiple properties at the same time.

Example of use:

  IGridSortState state = ... // acquire sort state
  
  if (state.getColumns().isEmpty() == false) { // at least one column is being sorted
     ISortStateColumn column = state.getColumns().get(0); // get the one with highest priority
     
     // property name is what IGridColumn.getSortProperty() returns
     String propertyName property = column.getPropertyName();
           
     // direction is either ASC or DESC
     IGridSortState.Direction direction = column.getDirection();
           
  }

getGrid

AbstractGrid<?,?> getGrid()

Returns:

the related grid, not null

getColumns

List<IGridSortState.ISortStateColumn> getColumns()

Returns the sort state values for various columns sorted by column priority. Columns with higher priority are placed before (have lower index than) columns with lower priority.

If your business logic supports sorting on one property only, you should sort by the first entry in the result list.

Returns:

list of IGridSortState.ISortStateColumn instances that determines the sort state of grid
