Re: How to send a node's attribute to another node

[guilhelm savin <guilhelm.savin AT gmail.com>]

Benjamin is right. There no specific function to "move" an attribute.

If you need to move only one attribute, the simplest way could be :

public void moveAttribute(String key, Node src, Node trg) {

    Object value = src.getAttribute(key);

    src.removeAttribute(key);

    trg.addAttribute(key, value);

}

...

Node a = ... ;

Node b = ... ;

moveAttribute("attr1", a, b);

Hope it helps ...

Regards.

Hi Daniele,

 

as far as I know there is no explicit function to do this. The following code might help you:

 

Node targetNode = ...;

Node sourceNode = ...;

for(String key : sourceNode.getAttributeKeySet()){

  targetNode.addAttribute(key, sourceNode.getAttribute(key));

}

node.clearAttributes();

 

All the best

Benjamin

Hi Guilhelm,

thanks for the prompt reply. Basically I need to move (something like cut 'n paste) an attribute from one node to another. Let's say nodeA has attribute1. I need to move it to nodeB. After the operation nodeA won't have attribute1 anymore and nodeB will have it. Maybe a method like "node.sendAttribute()" or something like this :-)

Sorry for the poor explanation in my previous mail.

Best Regards

Hi Daniele,

I  am not sure to understand what you want to do.
The following should work :

Node a, b;
b.setAttribute("attr1", a.getAttribute ("attr1"));

Is that you want to do ?

Regards
Guilhelm

Hi all,

each nodes inside my graph has various attributes. Every attribute consist of a string. I need a way to take a node's attribute and "transmit" it to another node.

Is there a specific method to do so? Sadly graphstream-project.org is down so I can't check the documentation.

Thank you in advance,

Daniele
