Class InstallSupport

java.lang.Object
  org.netbeans.api.autoupdate.InstallSupport

public final class InstallSupport
extends Object

Performs all operations scheduled on instance of OperationContainer. Instance of InstallSupport can be obtained by calling OperationContainer.getSupport()

Typical scenario how to use:

• Use instance of the OperationContainer created for chosen operation: OperationContainer.createForInstall() or OperationContainer.createForUninstall() and contained correct UpdateElements. See OperationContainer
• Call the doDownload(org.netbeans.api.progress.ProgressHandle, boolean) for downloading install data.
• Call the doValidate(org.netbeans.api.autoupdate.InstallSupport.Validator, org.netbeans.api.progress.ProgressHandle) for verify consistency of downloaded data.
• Call the doInstall(org.netbeans.api.autoupdate.InstallSupport.Installer, org.netbeans.api.progress.ProgressHandle) for install contained UpdateElement.
• If application restart is required for completing the Install/Update operation then call doRestart(org.netbeans.api.autoupdate.OperationSupport.Restarter, org.netbeans.api.progress.ProgressHandle) or doRestartLater(org.netbeans.api.autoupdate.OperationSupport.Restarter).

Code example:

 
 UpdateElement element = ...;
 OperationContainer<InstallSupport> container = createForInstall();
 ... add elements ...
 InstallSupport support = container.getSupport();
 Validator v = support.doDownload(null, false);
 Installer i = support.doValidate(v, null);
 Restarter r = support.doInstall(i, null);
 if (r != null) {
      support.doRestart(r, null);
 }

Method Detail

doDownload

public InstallSupport.Validator doDownload(ProgressHandle progress,
                                           boolean isGlobal)
                                    throws OperationException

Downloads all instances i.e. UpdateElements in corresponing OperationContainer.

Parameters:

progress - ProgressHandle for notification progress in downloading, can be null

isGlobal - if true then forces download instances into shared directories i.e. installation directory

Returns:

Validator an instance of Validator which allows to verify downloaded instances in the next step

Throws:

OperationException

doValidate

public InstallSupport.Installer doValidate(InstallSupport.Validator validator,
                                           ProgressHandle progress)
                                    throws OperationException

Validates all instances that have been downloaded in the previous step.

Parameters:

validator - an instance of Validator that has been returned by {link @doDownload}. Mustn't be null.

progress - ProgressHandle for notification progress in validation, can be null

Returns:

Installer an instance of Installer which allows to install all verified instances

Throws:

OperationException

doInstall

public OperationSupport.Restarter doInstall(InstallSupport.Installer installer,
                                            ProgressHandle progress)
                                     throws OperationException

Validates all instances that have been verified in the previous step.

Parameters:

installer - an instance of Installer that has been returned by InstallSupport#doValidate. Mustn't be null.

progress - ProgressHandle for notification progress in installation, can be null

Returns:

Restarter an instance of Restart if application restart is required for complete the install operation, or null
