QUESTION
I cannot find a way to use the Streams API and to have a short conditional addition to the 'pipeline' of an aggregate operation like a .distinct() call.
The following code shows how I have to duplicate the .filter call after the conditional .distinct() call, making the code more verbose than I'd like:
...ANSWER
Answered 2020-Oct-24 at 14:35As long as you don't do terminal operations multiple times on a single stream, it's okay to put the stream into a variable:
QUESTION
I have this code, and I have an algorithm to put the line between two nodes
. I want this line to join the #nodo4
with the #nodo6
, the rectangles
are the nodes
and each one has the same name as its id
.
The code is a bit long but the important part to achieve this is here:
...ANSWER
Answered 2020-Oct-03 at 19:31Don't override the datum
of source and target. That means you will not be able to redraw the tree, because you override all the values you need for it.
Also, don't use getBoundingClientRect()
. What if you zoom, or pan? It distorts and the line will never be at the correct place.
Instead, rely on the data you already gave the nodes, you have it already, and you can access it by calling .datum()
with no arguments! Then, it's no problem to calculate the positions the nodes will have, and also no problem to add a line exactly where you want it, regardless of zooming or scrolling.

QUESTION
I'm trying to connect two points with a line while moving one of them. I'm really lost in finding the real x, y position of anything on a document... I've read about how paddings, element sizes and all these things can mess up this process, but none of the tutorials or example codes worked. I would really appreciate if you could give my code a look and give a solution/url to some kind of tutorial or just a basic startingpoint. Thanks in advance!

We have two different firebase projects each with its own firebase functions and realtime database used.
we have come to a situation where we want to leverage one of the dataset (a node in the realtime db) from project 1 into the project 2.
As this node is read-only true so i can a access it in the format
https://myproject.firebaseio.com/prj1db/nodeX.json

QUESTION
After updating all of the libraries in my LibGDX project I’m getting an error that says
“Cause duplicate entry
META-INFMANIFEST.MF
”
when adding in the Appodeal SDK. When I click on the source of the error “:android:javaPreCompileDebug
” I get an error message that is insanely long, but I included part of it below.
I have migrated my project to AndroidX, all the libraries are up to date (unless I missed something) and I have done "Build > Clean Project" in Android Studio. I have had Appodeal working before in another project using an older version of LibGDX but I just created a new LibGDX project using the latest version and then went through making sure all of the libraries I’m using are up to date. Appodeal is the last thing I have to add to this project. The problem line is

QUESTION
In my vis.js network, I want to make a popup appear at the position of a node when I click on the node.
I used the getPositions method but the popup appears in the wrong place (too much on the left and top corner), as if the coordinates were incorrect.
...ANSWER
Answered 2019-Oct-06 at 23:47You are using network.getPositions(params.nodes[0]), but since the nodes can change a lot when zooming in and out and moving the network on the canvas somehow the positions do not match the real position of the node. I do not know if this is a bug in visjs or there is some other reason for it. The docs say they return the position of the node in the canvas space. But thats clearly not the case in your example.
Looking at the docs [ https://visjs.github.io/vis-network/docs/network/#Events ] the click event argument contains:

I'm trying to replace the 'return' from the sankey code below with a variable, but it's not returning as expected.

the value as a JSON string is to:
- Define the data as a JavaScript object literal
