# KFlow

Kotlin DSL for DAG-Flow execute engine.

## 1. Examples

* Quick start

```kotlin

// start ---> node1 ---> node2 ---> end

val flow = flow {

    // flow lines

    start to "node1" to "node2" to end

    // node handler

    "node1" {

        handler { flowData ->

            flowData["node1"] = "node1Data"

            println("${Thread.currentThread().name} -> node1 handle")

        }

    }

    "node2" {

        handler { flowData ->

            println("${Thread.currentThread().name} -> node2 handle, get node1 data ${flowData["node1"]}")

        }

    }

}

flow.execute()

```

* ForkJoin example

```kotlin

/**

 * start ---> node1 ------> node2 ---> node3 ----> end

 *              |                                  ↑

 *              |       |-----> f_node1 ---        |

 *              |---> f_node              |---> j_node

 *                      |-----> f_node2 ---

 */

```

You can reference to test cases.
