Interface ILaunchConfigurationDelegate2

All Superinterfaces:
ILaunchConfigurationDelegate
All Known Implementing Classes:
LaunchConfigurationDelegate
public interface ILaunchConfigurationDelegate2 extends ILaunchConfigurationDelegate
Optional enhancements to the launch configuration delegate interface. Allows launch delegates to abort a launch, build relevant projects in the workspace before a launch, and create the launch object to be used in a launch.

Clients implementing ILaunchConfigurationDelegate may also implement this interface.

3.0

  • Method Details

    • getLaunch

      ILaunch getLaunch(ILaunchConfiguration configuration, String mode) throws CoreException
      Returns a launch object to use when launching the given launch configuration in the given mode, or null if a new default launch object should be created by the debug platform. If a launch object is returned, its launch mode must match that of the mode specified in this method call.
      Parameters:
      configuration - the configuration being launched
      mode - the mode the configuration is being launched in
      Returns:
      a launch object or null
      Throws:
      CoreException - if unable to launch

    • buildForLaunch

      boolean buildForLaunch(ILaunchConfiguration configuration, String mode, IProgressMonitor monitor) throws CoreException
      Optionally performs any required building before launching the given configuration in the specified mode, and returns whether the debug platform should perform an incremental workspace build before the launch continues. If false is returned the launch will proceed without further building, and if true is returned an incremental build will be performed on the workspace before launching.

      This method is only called if the launch is invoked with flag indicating building should take place before the launch. This is done via the method ILaunchConfiguration.launch(String mode, IProgressMonitor monitor, boolean build).

      Parameters:
      configuration - the configuration being launched
      mode - the mode the configuration is being launched in
      monitor - progress monitor, or null. A cancelable progress monitor is provided by the Job framework. It should be noted that the setCanceled(boolean) method should never be called on the provided monitor or the monitor passed to any delegates from this method; due to a limitation in the progress monitor framework using the setCanceled method can cause entire workspace batch jobs to be canceled, as the canceled flag is propagated up the top-level parent monitor. The provided monitor is not guaranteed to have been started.
      Returns:
      whether the debug platform should perform an incremental workspace build before the launch
      Throws:
      CoreException - if an exception occurs while building

    • finalLaunchCheck

      boolean finalLaunchCheck(ILaunchConfiguration configuration, String mode, IProgressMonitor monitor) throws CoreException
      Returns whether a launch should proceed. This method is called after preLaunchCheck() and buildForLaunch() providing a final chance for this launch delegate to abort a launch if required. For example, a delegate could cancel a launch if it discovered compilation errors that would prevent the launch from succeeding.
      Parameters:
      configuration - the configuration being launched
      mode - launch mode
      monitor - progress monitor, or null. A cancelable progress monitor is provided by the Job framework. It should be noted that the setCanceled(boolean) method should never be called on the provided monitor or the monitor passed to any delegates from this method; due to a limitation in the progress monitor framework using the setCanceled method can cause entire workspace batch jobs to be canceled, as the canceled flag is propagated up the top-level parent monitor. The provided monitor is not guaranteed to have been started.
      Returns:
      whether the launch should proceed
      Throws:
      CoreException - if an exception occurs during final checks

    • preLaunchCheck

      boolean preLaunchCheck(ILaunchConfiguration configuration, String mode, IProgressMonitor monitor) throws CoreException
      Returns whether a launch should proceed. This method is called first in the launch sequence providing an opportunity for this launch delegate to abort the launch.
      Parameters:
      configuration - configuration being launched
      mode - launch mode
      monitor - progress monitor, or null. A cancelable progress monitor is provided by the Job framework. It should be noted that the setCanceled(boolean) method should never be called on the provided monitor or the monitor passed to any delegates from this method; due to a limitation in the progress monitor framework using the setCanceled method can cause entire workspace batch jobs to be canceled, as the canceled flag is propagated up the top-level parent monitor. The provided monitor is not guaranteed to have been started.
      Returns:
      whether the launch should proceed
      Throws:
      CoreException - if an exception occurs while performing pre-launch checks
