Subject: [JAVA3D] dispose the children of a detached BranchGroup


Hi, every one:

I have a problem with disposing the contents of a detached Branchgroup
without setting the BranchGroup to null.
I have a BranchGroup generated dynamically through the user interacting
with the program. I need to often to detach the BranchGroup and would like
to garbage collect its children. I tried two approaches as follows:

1.
                                        int numb = theGroup.numChildren();
                                        System.out.println("numb="+numb);
                                        for (int index=0; index<numb-1;
index++)
                                                theGroup.removeChild(index);

I got the error of "ArrayIndexOutOfBoundry, 19>=19 " although numb=38.

2.
                                        Enumeration enu =
theGroup.getAllChildren();
                                        while (enu.hasMoreElements())

enu.nextElement().remove();

for this approach, I got required variable, found value for the last
statement.

My question is how can I dispose the children of a detached BranchGroup
without setting this BranchGroup to null. I need to keep it for re-use
later.

Thanks in advance for any suggestion.
