| Process.ProcessCallback |
| Class | Description |
|---|---|
| DecisionGateway |
Chooses a next element in a
Process by evaluating a series of criteria against
the Process.state and choosing the element associated with
the criteria that matched, or a defaultElement if none of the criteria match. |
| Process |
A instance of Process represents a stateful process executing a series of Tasks,
which may be:
user interactions
calls to DataSources (hence: any database or web service)
arbitrary code
other Processes
A Process is stateful in the sense that it maintains
state
across the different tasks that are executed. |
| ProcessElement |
A ProcessElement is an abstract superclass for elements involved in a
Process,
such as a Task or XORGateway. |
| ProcessSequence |
An Array of
ProcessElements involved in a Process. |
| ScriptTask |
Task that executes arbitrary code, either synchronous or asynchronous.
|
| ServiceTask |
A ServiceTask is an element of a
Process which calls a DataSource operation,
optionally using part of the process state as inputs or
storing outputs in the process state. |
| StateTask |
StateTask can either copy fields of
Process.state to other
fields, or apply hardcoded values to Process.state via value. |
| Task |
A Task is an abstract superclass for
Process and for all Task types that can
be involved in a Process, such as a ServiceTask. |
| UserTask |
A task that involves showing a user interface to the end user allowing the user to view and input data and press a
button (or do some other UI gesture) to complete the task.
|
| XORGateway |
Chooses one or another next process element based on AdvancedCriteria applied to
Process.state. |
