Task and TaskReqmt Models
There are 2 models that make up the Task framework: Task and TaskReqmt.
Table 15.1. Task Fields
| Field | Required | Description |
|---|---|---|
| ID | Required | Unique ID is the sole Natural Key for this Task. |
| OwningOrg | Required | A model link to an Owning Organization for the Task. |
| TaskType | Required | Fully-qualified Java class name extending the base class com.onenetwork.platform.common.task.AbstractTaskType, which has callbacks like onStart and onComplete that are called when the task changes state. |
| State | Required | Holds the state for the Task and is governed by its state machine. Currently, the state machine contains 3 states: Pending, InProgress, and Completed. |
| ParentTask | Optional | A model link to a parent Task. |
| Sequence | Required for Tasks with a non-null ParentTask | This should be a unique integer among the direct child Tasks for a parent Task; it dictates the order they appear in the UI. |
| RequiredForParentCompletion | Optional | If set to true, then this Task must enter the Completed state before its parent Task. |
| AutocompleteOnChildrenComplete | Optional | If set to true, then this Task will automatically enter the Completed state when the last required child Task is Completed. |
| ParamsJSON | Optional | This is a CLOB of JSON for holding TaskType-dependent parameters needed at runtime. This will be discussed in more detail later. |
Table 15.2. TaskReqmt Fields
| Field | Required | Description |
|---|---|---|
| RequiringTask | Required | A model link to a Task that has a dependency on another Task. |
| RequiredTask | Required | A model link to a Task that is needed by the RequiringTask. |
| RequirementType | Required | There is currently only 1 type: BeforeStart, which dictates that the RequiringTask cannot move from the Pending state to InProgress until RequiredTask has been marked Completed. |
