public interface TaskIO
Process statewhen the task is started, and outputs, which can be thought of as atomically applied to the Process state when a task is completed.
Task can use
Task.inputField to specify the field from the Process state that should be used as inputs, and
Task.outputField to specify the
field from the Process state that the task should output to.
More complex tasks can take
multiple fields from the process state via
Task.inputFieldList and write to
multiple fields of the process state via
Task.outputFieldList. In this case,
the task is said to have an "input Record" and/or "output Record", which can be thought of as a
copy of the process state Record with only the fields listed in the
specified, the inputField is considered the "primary" input field and will be used
automatically by various Task subclasses.
