The ProgressObject structure allows the user the option of polling for status or to provide a callback.

Method Summary

void addProgressListener(ProgressListener pol)
          Add a listener to receive Progress events on deployment actions.

void cancel()
          (optional) A cancel request on an in-process operation stops all further processing of the operation and returns the environment to it original state before the operation was executed.

ClientConfiguration getClientConfiguration(TargetModuleID id)
          Return the ClientConfiguration object associated with the TargetModuleID.

DeploymentStatus getDeploymentStatus()
          Retrieve the status of this activity.

TargetModuleID[] getResultTargetModuleIDs()
          Retrieve the list of TargetModuleIDs successfully processed or created by the associated DeploymentManager operation.

boolean isCancelSupported()
          Tests whether the vendor supports a cancel opertation for deployment activities.

boolean isStopSupported()
          Tests whether the vendor supports a stop opertation for deployment activities.

void removeProgressListener(ProgressListener pol)
          Remove a ProgressObject listener.

void stop()
          (optional) A stop request on an in-process operation allows the operation on the current TargetModuleID to run to completion but does not process any of the remaining unprocessed TargetModuleID objects.
