RowReorderStartCommand

public RowReorderStartCommand(ILayer layer,
                              int fromRowPosition)

Returns:

The position of the row that should be reordered

convertToTargetLayer

public boolean convertToTargetLayer(ILayer targetLayer)

Description copied from interface: ILayerCommand

Convert the row/column coordinates the command might be carrying from the source layer to the destination (target) layer.

Note: Commands should not be processed if they fail conversion.

Specified by:

convertToTargetLayer in interface ILayerCommand

Parameters:

targetLayer - the target layer

Returns:
