Description copied from class: AbstractTask

Handle a call to execution. The state will have been updated to Task.State.RUNNING prior to this method. This method should call AbstractTask.updateState(org.praxislive.ide.core.api.Task.State) to change the state returned from AbstractTask.execute(), or update the state at a later point. If this method throws an exception, the task will be set to the Task.State.ERROR state.

Specified by:

handleExecute in class AbstractTask

Throws:

Exception - if the task cannot be executed

handleCancel

protected boolean handleCancel()

Description copied from class: AbstractTask

If the task is cancellable, this method should be overridden and handle any necessary steps, returning true if the task has been cancelled. The state will be updated automatically.

Overrides:

Returns:

true to have task marked as cancelled
