Define a function that can be used in Stellar

Hi all, Is there any way that we can define a function that can be used rather than duplicating a logic multiple times? Cheers, Ali

Re: Define a function that can be used in Stellar

At present you can certainly create custom stellar functions in Java. I’m guessing however that what you’re looking to do is create a kind of function that combines a number of stellar functions to avoid repetition, or to ensure consistency of certain parameters for example. Is that what you’re

Re: Define a function that can be used in Stellar

Hi Simon, Yes, that is exactly what we are looking for. Is there any example regarding adding a Stellar function in Java? Hopefully, we don't need to rebuild the corresponding modules for this? Cheers, Ali On Wed, Jan 17, 2018 at 8:40 PM, Simon Elliston Ball < si...@simonellistonball.com> wrote:

Re: Define a function that can be used in Stellar

https://github.com/apache/metron/tree/master/metron-stellar/stellar-3rd-party-example gives good details on how to add a stellar function. Stellar will pick up an annotated function on its class path, so to

Re: Define a function that can be used in Stellar

Thanks, Simon. We have already got a script to deal with classpath management for the parsers. We should be able to use it for this extension as well. Yeah, I agree. It will be much easier to define functions on the fly and use them afterwards. It could be defined as Lambda or custom function. Re

Re: Define a function that can be used in Stellar

Ali - Can you describe the logic that you are trying to perform? That would be useful as a use case to help drive a discussion around creating named functions in Stellar. On Wed, Jan 17, 2018 at 6:29 AM Ali Nazemian wrote: > Thanks, Simon. We have already got a script to deal with classpath >

Re: Define a function that can be used in Stellar

It is a bit complex. We want to create a function that accepts a list of arguments for an asset and generate an asset identifier that can be used as a row_key for the enrichment store. The logic would be complicated, though. We may need to include some sort of similarity aware hash function as a pa

Re: Define a function that can be used in Stellar

Have you looked at the recent TLSH functions in Stellar? We already have that for similarity preserving hashes. Simon > On 17 Jan 2018, at 12:35, Ali Nazemian wrote: > > It is a bit complex. We want to create a function that accepts a list of > arguments for an asset and generate an asset ide

Re: Define a function that can be used in Stellar

If something we have already does not fit the bill, I would recommend creating that function in Java. Since you described it as "a bit complex" and "the logic would be complicated" I don't see any value in defining something like this in Stellar with named functions. Best On Wed, Jan 17, 201
