Method Detail

pivotGestureHappened

boolean pivotGestureHappened(java.lang.Object source,
                             int fromEdge,
                             int toEdge,
                             int fromLayer,
                             int toLayer,
                             int flags)
                             throws EdgeOutOfRangeException,
                                    LayerOutOfRangeException,
                                    DataDirectorException

Pivots data. This method first fires a viewPivotRequesting event. If the event is not consumed, this method then calls the pivot method in the data director, to pivot the data in the data source. After the call to the data director, this method fires a viewPivotRequested event.

The view calls this method when a pivot gesture is detected in the UI.

Parameters:

source - The source of any events that this method fires. The DataView passes this as this parameter.

fromEdge - A constant that represents the edge to pivot from, such as COLUMN_EDGE. Edge constants are defined in the DataDirector interface.

toEdge - A constant that represents the edge to pivot to.

fromLayer - The layer to pivot from. The layer identifies the location of the dimension or dimension member on the edge. Zero is the outer-most dimension on the edge.

toLayer - The layer to pivot to.

flags - A constant that represents the type of pivot to perform, such as PIVOT_SWAP or PIVOT_MOVE_BEFORE. The constants are defined in the DataDirector interface, and they all begin with PIVOT_.

Returns:

true if the data director performs the pivot, false if the pivot is not performed for some reason.

Throws:

EdgeOutOfRangeException - If either edge parameter is too large.

LayerOutOfRangeException - If either layer parameter is negative or too large.

DataDirectorException - If a data provider error occurs.

                        LayerOutOfRangeException,
                        DataDirectorException

Indicates whether a pivot operation is legal. This method calls the pivotOK method in the data director, to pivot the data in the data source. The view calls this method when a pivot gesture is detected in the UI.

Parameters:

source - The source of any events that this method fires. The DataView passes this as this parameter.

fromEdge - A constant that represents the edge to pivot from, such as COLUMN_EDGE. Edge constants are defined in the DataDirector interface.

toEdge - A constant that represents the edge to pivot to.

fromLayer - The layer to pivot from. The layer identifies the location of the dimension or dimension member on the edge. Zero is the outer-most dimension on the edge.

toLayer - The layer to pivot to.

flags - A constant that represents the type of pivot to perform, such as PIVOT_SWAP or PIVOT_MOVE_BEFORE. The constants are defined in the DataDirector interface, and they all begin with PIVOT_.

Returns:

true if the pivot operation is legal, false if not.

Throws:

EdgeOutOfRangeException - If either edge parameter is too large.

LayerOutOfRangeException - If either layer parameter is negative or too large.

DataDirectorException - If a data provider error occurs.

drillGestureHappened

boolean drillGestureHappened(java.lang.Object source,
                             int edge,
                             int layer,
                             int slice,
                             int flags)
                             throws EdgeOutOfRangeException,
                                    LayerOutOfRangeException,
                                    SliceOutOfRangeException,
                                    DataDirectorException

Drills in data. The view calls this method when a drill gesture is detected in the UI.

Parameters:

source - The source of any events that this method fires. The DataView passes this as this parameter.

edge - A constant that represents the edge to drill, such as COLUMN_EDGE. Edge constants are defined in the DataDirector interface.

layer - The layer to drill. The layer identifies the location of the dimension or dimension member on the edge. Zero is the outer-most layer on the edge.

slice - The slice to drill. The slice is zero-based. Each layer member in the innermost dimension has a unique slice. In outer layers, any slice that the outer layer spans can be used.

flags - A constant that represents the type of drill to perform, such as DRILLSTATE_DRILLABLE to drill down in data. Drill constants are defined in the DataDirector interface. They begin with DRILLSTATE_.

Returns:

true if the data director performs the drill, false if not.

Throws:

EdgeOutOfRangeException - If edge is too large.

LayerOutOfRangeException - If layer is negative or too large.

SliceOutOfRangeException - If slice is negative or too large.

DataDirectorException - If a data provider error occurs.
