Field Detail

restorableStatus

protected S restorableStatus

The ScenarioSimulationContext.Status to restore when calling undo/redo. Needed only for undoable commands.

Constructor Detail

AbstractScenarioSimulationUndoableCommand

public AbstractScenarioSimulationUndoableCommand()

Method Detail

setCurrentContext

protected abstract org.kie.workbench.common.command.client.CommandResult<ScenarioSimulationViolation> setCurrentContext(ScenarioSimulationContext context)

The action to perform when an UNDO or REDO is required on this command. Typically it restores the previous status and it stores the current one.

Parameters:

context -

Returns:

setRestorableStatusPreExecution

protected abstract S setRestorableStatusPreExecution(ScenarioSimulationContext context)

It sets the status BEFORE the command is launched. Typically it clones the current status before changes are applied.

Parameters:

context -

Returns:

commonUndoRedoPreExecution

public abstract Optional<org.kie.workbench.common.command.client.CommandResult<ScenarioSimulationViolation>> commonUndoRedoPreExecution(ScenarioSimulationContext context)

Method called soon before actual undo and redo operations to preliminary execute a tab switch without altering the call stack. (eg If the command change the status of a not shown grid, this switches the tab)

Parameters:

context -

Returns:

Optional<CommandResult<ScenarioSimulationViolation>> of CommandResultBuilder.SUCCESS if a tab switch happened, otherwise Optional.empty()

execute

public org.kie.workbench.common.command.client.CommandResult<ScenarioSimulationViolation> execute(ScenarioSimulationContext context)

Specified by:

execute in interface org.kie.workbench.common.command.client.Command<ScenarioSimulationContext,ScenarioSimulationViolation>

Overrides:

execute in class AbstractScenarioSimulationCommand

undo

public org.kie.workbench.common.command.client.CommandResult<ScenarioSimulationViolation> undo(ScenarioSimulationContext context)

Specified by:

undo in interface org.kie.workbench.common.command.client.Command<ScenarioSimulationContext,ScenarioSimulationViolation>

Overrides:

undo in class AbstractScenarioSimulationCommand

redo

public org.kie.workbench.common.command.client.CommandResult<ScenarioSimulationViolation> redo(ScenarioSimulationContext context)
