InstallsAwareAction

public InstallsAwareAction()

Method Detail

getState

protected abstract ControllerState getState()

Get the action's state.

Returns:

get the action's state

installAction

public void installAction(KernelControllerContext context)
                   throws Throwable

Description copied from class: SimpleControllerContextAction

The install.

Overrides:

installAction in class KernelControllerContextAction

Parameters:

context - the context

Throws:

Throwable - for any error

doInstalls

protected void doInstalls(KernelControllerContext context)
                   throws Throwable

Execute the installs.

Parameters:

context - the context

Throws:

Throwable - for any error

considerUninstalls

protected void considerUninstalls(KernelControllerContext context,
                                  int index)

Consider the uninstalls. This method is here to be able to override the behavior after installs failed. e.g. perhaps only running uninstalls from the index. By default we run all uninstalls in the case at least one install failed.

Parameters:

context - the context

index - current installs index

undoInstallAction

protected void undoInstallAction(KernelControllerContext context)

Undo the steps from install action in the case of failed installs. Usually this is what uninstallActionInternal does.

Parameters:

context - the context

uninstallAction

public void uninstallAction(KernelControllerContext context)

Description copied from class: SimpleControllerContextAction

The uninstall.

Overrides:

uninstallAction in class KernelControllerContextAction

Parameters:

context - the context

doUninstalls

protected void doUninstalls(KernelControllerContext context)

Execute uninstalls

Parameters:

context - the context

doUninstalls

protected void doUninstalls(KernelControllerContext context,
                            int index)

Execute uninstalls from the index. Leaving this method here in case someone wants to use 'symetric' approach to uninstalling installs.

Parameters:

context - the context

index - the current index
