Illustrates how to define a data class for your workflow and wire it's properties up to the inputs and outputs of steps.
First, we define a class to hold data for our workflow.
public class MyData {
public int value1;
public int value2;
public int value3;
}Then we create a step with inputs and outputs, by simply exposing public properties.
public class AddNumbers implements StepBody {
public int number1;
public int number2;
public int answer;
@Override
public ExecutionResult run(StepExecutionContext context) {
answer = number1 + number2;
return ExecutionResult.next();
}
}Then we put it all together in a workflow.
public class DataWorkflow implements Workflow<MyData> {
@Override
public void build(WorkflowBuilder<MyData> builder) {
builder
.startsWith(AddNumbers.class)
.input((step, data) -> step.number1 = data.value1)
.input((step, data) -> step.number2 = data.value2)
.output((step, data) -> data.value3 = step.answer)
.then(DisplayAnswer.class)
.input((step, data) -> step.answer = data.value3);
}
...
}
