Stream filter querying Blockchain

+2 votes
Hello, I want to validate certain fields of object streams. There is a way to query the stream inside the filter function to retrieve the last value of that x field?
It would be something like this:
1) Get the last value of x field with that specific key
2) Verify if the inserted value is greater then the last one inserted.

I hope this is clear. If it is not clear I can describe better this scenario.

I'm afraid it's not yet possible to query the stream from within a stream filter, in order to apply this kind of rule, but we're looking into adding this in future.
