Look at it.
Look at brick menu under JVS category.
See if brick in question is on menu.
Make descision.
edit: oh no wait you wanted a variable or something, one second
Try this:
function iscontent(%brick)
{
if(strpos(16035.getDatablock().getname(),"content") != -1)
return 1;
else
return 0;
}
All JVS bricks are apparently supposed to contain the word "content" as a part of their datablock.
As far as I know only JVS bricks have that distinction.
Add the function to your script, and you can simply do:
echo(iscontent($mybrick));
for example, to try it.
