Multiple smartEndSnapshot calls

[rajesh.palanisamy]

HI Giuseppe,

Thanks for the quick reply,

I am going for the second option - communication between metaData and data adapter.

Is there a direct way to trigger the subscribe method of data adapter from notifyNewTable call, i could see Demos with volatile attributes which trigger the data pull for each item. Apart from that do you have any other recommendation for the communication.

Thanks
Rajesh

Hi Rajesh,

Yes you are right, the most convenient solution, especially in case of Java adapters, is that the Metadata holds a reference to the Data Provider instance, and perform direct calls when needed.

That said, please consider also the possibility that the Metadata call not the subscribe method but a different method in order to distinguish the two cases, the regular subscribe call from the Lightstreamer server, from Metadata incoming calls.

Regards,
Giuseppe

Thanks Giuseppe its acknowledged, I will make sure we have different method calls.

One question, is it possible to use spring Application events for metaData and data adapter communications? Implement ApplicationListener<ApplicationEvent> in our DATA Adapters so we can fire an application event from metaDataAdapter once notifyNewTables is called.

To put in simple words,
can we initialize spring context inside adapter life cycle classes ?

Thanks
