[Berthing Jesper]

Hi Adi,
 
I think your question is clear. 
 
You are using the functions correctly, but you need to be sure that the
atomName is a key in the HashTable.
 
Please use outConne.toString() and print it somewhere visible to you,
then you are able to se what the HashTable contains.
Or you can use outConne.isEmpty
<http://java.sun.com/j2se/1.4.2/docs/api/java/util/Hashtable.html#isEmpt
y()> ()that returns true if outConne is empty (No out connections from
the atomObject).
 
\Jesper

Hi Jesper,


1. Hashtable outConne= atomObject.getOutConnections();

2. Vector list = (Vector)outConne.get(atomName);

In the 1 statement, atomObject is the object of  type JBuilderAtom or
JBuilderModel.  What exactly I am trying to do in the above two
statements is 
1. finding out the out connections (if any) for the JBuilderAtom or
JBuilderModel.
I hope this can be achieved thorough the first statement.
2. Next is getting those connections from the hash table with the name
of the above object.


I hope cleared my problem.

Regards
Adi

	Hi Adi,
	
	It looks correct, if the atomName[i] is a stored as a key in the
HashTable.
	So if you say that it returns null, the it is not present in the
HashTable.
	
	Try: (I guess that atomName[i] is the name of your connections
from the MetaModel) 
	
	if(true == outConne.containsKey(atomName[i])
	{
	   Vector list = (Vector)outConne.get(atomName[i]);
	}
	else
	{
	   // Look for another connection
	}
	
	toString() function from the HashTable class is also a good way
to visualize the content of the HashTable.

	Is anyone in the list know about the following problem.
	
	
	
	1. Hashtable outConne= atomNames[i].getOutConnections(); 
	
	2. Vector list = (Vector)outConne.get(atomName[i]);
	Are the above statements correct?
	I am getting null in the 2 statement. Is it the right way to
access the
	hashtable list?
	
	Regards
	Adi
