How To Build

Reqirements

Java >= 1.8.0_60
Internet connection (other dependencies are downloaded automatically)
IDE: Gradle Plugin (not necessary for command line usage)

IDE

Open the VWorkflows Gradle project in your favourite IDE (tested with NetBeans 8.1) and build it by calling the assemble task.

Command Line

Navigate to the Gradle project (e.g., path/to/VWorkflows) and enter the following command

Bash (Linux/OS X/Cygwin/other Unix-like OS)

./gradlew assemble

Windows (CMD)

gradlew assemble

Test It

Besides the tests defined in VWorkflows-Core (test task) it is also possible to run a graphical demo that comes with VWorkflows-Demo subproject. To run it call the run task.

Comments

Multiple in / out

Hi, very nice project you have here.

I have watched a couple videos and scanned some code, I couldn't figure out if this library allows for multiple in and out connections to a node. In all the videos I only see one in and out per node.

I have a use case where I would definitely use this library and possibly help contribute if I were able to hook up multiple connections to nodes. Sorry if there is api where this would be obvious, I tried to find the answer quickly. :)

A bound value cannot be set

I am running a modified and simplified version of your demo within Luna Eclipse and Java 8.

I can add a node just fine, however, when I add an input or output, I get the following error:

Any clue what I am doing wrong?

Implementation question

I had an idea for an application that could be visualized using VWorkflows. The idea is to have events that trigger specific actions (for example a scheduled task or watching a directory for a new file). The trigger will then provide the specific file or a start signal to the next node that will be process the file in a specific manner. The goal is to create a tool that can be used to automate tasks (like sorting files, triggering backups etc.). All actions (like moving, copying, renaming files, deleting) could be visualized as a node with an input of accepts a file and an output that provides the new file or nothing. I couldn't really figure out how to pass information from one node to another via a connection. I created two nodes with the same type of output and input, connected them and tried to pass data over via the value object property but that doesn't seem to work out that well. Could you help me out please? Any help is appreciated. I tried to look into vrlstudio but couldn't find the part where data is transmitted/received via the node's connections.

Extension points
This PR addresses the following points:

reduce code duplication between FXConnectionSkin and FXNewConnectionSkin by adding a type in between.

expose package private classes as public.

apply license headers to all files

WARNING: The AbstractFXConnectionSkin classes follows the template method pattern to let its subclasses initialize various aspects. This leads to an explicit invocation of the init() method right after the constructor is invoked.

Possible NPE in eu.mihosoft.vrl.workflow.VFlowImpl

Given 2 connected nodes, removing a node will throw NPE in VFlowImpl.init Guarding with a null check will solve the issue, but not sure if this is the best solution.

net.nemerosa:versioning plugin requires external git client

Currently, the net.nemerosa:versioning plugin depends on git/git.exe executables. This is a disadvantage, especially on Windows. For unexperienced users this behavior causes a lot of trouble since most of the time, the git-client provided by the IDE is sufficient and the dependency to an additional git executable complicates the build process.

Connections not Showing Up

I'm fairly new at this, but I didn't see any tutorials or sample code online besides those found on this repository.

Basically, I'm using one of the tutorial programs on the website, but it doesn't seem to show any of the connections or the connectors on the nodes themselves. I'll include the code I'm using, as well as a screen shot of what it looks like.

Use only a single timerthread

Since every event did create a new thread the library was very thread intensive. With this change, only a single thread is used. This significantly improves the performance for complex flows.

Improve GRADLE build Performance

Parallel builds. This project contains multiple modules. Parallel builds can improve the build speed by executing tasks in parallel. We can enable this feature by setting org.gradle.parallel=true.

File system watching. Since Gradle 6.5, File system watching was introduced which can help to avoid unnecessary I/O. This feature is the default since 7.0. For an older version, we can enable this feature by setting org.gradle.vfs.watch=true.

Configuration on demand. Configuration on demand tells Gradle to configure modules that only are relevant to the requested tasks instead of configuring all of them. We can enable this feature by setting org.gradle.configureondemand=true.

gradle caching. Shared caches can reduce the number of tasks you need to execute by reusing outputs already generated elsewhere. This can significantly decrease build times. We can enable this feature by setting org.gradle.caching=true.

===================== If there are any inappropriate modifications in this PR, please give me a reply and I will change them.

VisualizationRequest.KEY_NODE_NOT_REMOVABLE has no effect

I am trying to disable/hide the 'X' button in a VNode that is rendered in a VCanvas. Here's the code snippet that I wrote to do it:

DefaultValueObject dvo = new DefaultValueObject(); dvo.setValue(myObject); VNode node = workflow.newNode(dvo); node.getVisualizationRequest().set(VisualizationRequest.KEY_NODE_NOT_REMOVABLE, true);

Unfortunately, it has no effect. I have tried it both when creating the node, but also inside a custom class that extends the FXFlowNodeSkinBase.

Am I doing something wrong?

PS. Is this project still active?

Add event handler for connection

Hello,

Would someone enlighten me on how to add event handlers for connections in the controller? I know that we can define custom connection skin and handle in there but I would like to manipulate connection objects from inside my controllers.

Thanks.
