All Implemented Interfaces:

ILayerCommand

public class TickUpdateCommand
extends Object
implements ILayerCommand

Command to trigger a tick update on the current selected cells. Note: This command only works if the layer composition contains a SelectionLayer and the corresponding TickUpdateCommandHandler is registered.

Constructor Detail

TickUpdateCommand

public TickUpdateCommand(IConfigRegistry configRegistry,
                         boolean increment)

Parameters:

configRegistry - The IConfigRegistry of the current NatTable instance this command is executed in. Needed to determine several configurations on handling this command by its handler. As the command handler is not aware of the NatTable instance it is running in, and there is no kind of context, the IConfigRegistry needs to be transported.

increment - Flag to determine whether the current value in the data model should be incremented or decremented.

TickUpdateCommand

protected TickUpdateCommand(TickUpdateCommand command)

Constructor that is used by local cloning operation.

Parameters:

command - The command to create a new instance of.

Method Detail

cloneCommand

public TickUpdateCommand 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

GridLayer.doCommand(ILayerCommand)

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true if the command is valid after conversion, false if the command is no longer valid.

getConfigRegistry

public IConfigRegistry getConfigRegistry()

Returns:

The IConfigRegistry of the current NatTable instance this command is executed in. Needed to determine several configurations on handling this command by its handler. As the command handler is not aware of the NatTable instance it is running in, and there is no kind of context, the IConfigRegistry needs to be transported.

isIncrement

public boolean isIncrement()

Returns:

Whether the current value in the data model should be incremented or decremented.
