Consults the dependent about a possible veto on disposal.
Consults the dependent about a possible veto on disposal. This does not dispose the dependent, it simply returns the state, which is either
None
(ok to proceed withdispose
) or someVeto
instance that should be resolved before callingdispose
.The normal procedure is to call the veto's
tryResolveVeto
first, and when it returnstrue
, to proceed and calldispose
. If it returnsfalse
, the disposable should be aborted.
