Constructor Detail

ColumnReorderEndCommand

public ColumnReorderEndCommand(ILayer layer,
                               int toColumnPosition)

Parameters:

layer - The layer to which the column positions match.

toColumnPosition - The target column position to reorder to.

ColumnReorderEndCommand

protected ColumnReorderEndCommand(ColumnReorderEndCommand command)

Clone constructor.

Parameters:

command - The command to clone.

Method Detail

getToColumnPosition

public int getToColumnPosition()

Returns:

The column position to which the column should be reordered to.

updateToColumnPosition

public void updateToColumnPosition(int toPosition)

Parameters:

toPosition - The new toColumnPosition.

Since:

1.6

toggleCoordinateByEdge

public void toggleCoordinateByEdge()

Toggles the coordinate from left edge to right edge and vice versa. Will not toggle if the coordinate is right edge of the last column or the left edge of the first column.

Since:

1.6

isReorderToLeftEdge

public boolean isReorderToLeftEdge()

Returns:

true if the reorder operation should be done on the left edge of the toColumnPosition, false if it should be reordered to the right edge.

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true if the command is valid after conversion, false if the command is no longer valid.

cloneCommand

public ColumnReorderEndCommand cloneCommand()

Description copied from interface: ILayerCommand

Same semantics as Object.clone() Used to make a copies of the command if has to passed to different layer stacks.

Specified by:

cloneCommand in interface ILayerCommand

Returns:

a cloned instance of the command
