Order of CASes after multiplier

[Aaron Kaplan <aa...@xrce.xerox.com>]

I can't find this documented anywhere, but I observe empirically that
components downstream of a CAS multiplier receive all of the new CASes
generated by that multiplier before receiving the original CAS that was
the input to the multiplier.  Can I rely on that order?

Hi Aaron,

Yes, for a synchronous UIMA aggregate the parent CAS is released only after
all its children are released.

When deployed asynchronously in UIMA AS, the parent CAS is released from the
CM when hasNext returns false, and is then available to be routed. If the
parent CAS comes into an async aggregate on a process call (that it, it is
not itself generated by a CM inside), it will not be returned until all of
its children CAS have been released; this allows an error on a child CAS to
[optionally] generate an error on its parent CAS.
