public abstract class TaskCommand
extends Object
implements Serializable
```
This command class is used to allow communication of parameters for a task between a client and task running service, which might be on a different computer. This class can be used directly, or extended to create a command object to pass parameters for a specific task. See for example ExpressionExperimentLoadTaskCommand. A entityId field is provided as a convenience for the case when a primary key is all that is really needed.

    Obtain the class of the Task object that will be run for this command.
    If null, the task command cannot be submitted through TaskRunningService.submitTaskCommand(TaskCommand) and a task object must be explicitly created.
    For now, this how we map from TaskCommand to Task that actually runs it. We have to have this mapping somewhere until we make Tasks themselves serializable. Tasks are not readily serializable because they have dependencies to Spring services. at which point TaskCommand can be deprecated(or remain as TaskContext).
