AbstractMultiColumnCommand

protected AbstractMultiColumnCommand(ILayer layer,
                                     int... columnPositions)

Parameters:

layer - The ILayer to which the positions match.

columnPositions - The positions that should be processed by this command.

AbstractMultiColumnCommand

protected AbstractMultiColumnCommand(AbstractMultiColumnCommand command)

Clone constructor

Parameters:

command - The command to clone.

Method Detail

getColumnPositions

public Collection<Integer> getColumnPositions()

Returns:

The unique column positions that should be processed by this command.

getColumnPositionsArray

public int[] getColumnPositionsArray()

Returns:

The unique column positions that should be processed by this command.

Since:

2.0

setColumnPositions

protected final void setColumnPositions(ILayer layer,
                                        int... columnPositions)

Parameters:

layer - The ILayer to which the positions match.

columnPositions - The positions that should be processed by this command.

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. If it is not possible to convert the command to the target layer, then this method will return false and the state of this command object will remain unchanged. Note: Commands should not be processed if they fail conversion.

Specified by:

convertToTargetLayer in interface ILayerCommand

Parameters:

targetLayer - the target layer

Returns:

true if the command is valid after conversion, false if the command is no longer valid.
