What does this symbol "O" on the arrow indicate?
O

What are other symbols available like this, i cannot find them in Fowler or Larmans books!

If the arrow represents an association, then the "O" would probably be a "0" (zero) to indicate multiplicity or how many objects can be involved in the relationship. Usually you'd have another symbol at the other end such as a number or N or *. E.g. 0->1 or 0->N or 0->*.

Hi Junilu,
Its not about "0", i know about multiplicity. Its about a "O" on the arrow located at the center of the arrow.
<pre> O

i guess its something related to asynchronous, or time out related symbol. I have seen it long time back some where, but i don't remember the resource.

If you don't remember the resource, you may not remember the exact symbol .
Isn't the Booch symbol <--O to indicate that an object is returned ?
Or it may also figure a clock when you have a basic character set.
