Question - Handlers

[ObiWahn]

Hi,

is it possible to inherit from the NodeLocationsForWays and SimpleHandler? How can i keep the node locations and have functions like apply?

Update:

Somehow the doc and examples are extremely confusing ot me. The SimpleHandler has some sort of apply itself. While it seems that the regular way is to use osmium.apply with a file and a list of handlers that are executed in order. So the SimpleHandler having its own apply functions seems a bit odd to me.
When I look at the using node cache sample the reader uses osmium.osm.osm_entity_bits.WAY can it still fill the node cache or are the nodes skipped by the reader?

NodeLocationsForWays is a handler like any other. You can just add it to your handler chain and then have the node locations available in later handlers.

SimpleHandler.apply_*() functions are a convenience function which offer some additional setup around the raw osmium.apply depending on what callbacks you have installed. Among other things, they will set up the location handler for you, when needed. They cannot handle handler chains but will only apply a single handler.

At this point it might be helpful if you tell us what exactly you want to achieve. Without understanding your goal it is difficult to understand the questions.

Thanks for the reply I just saw it now after posting another question. Somehow I must have missed the notification that the ticket was moved here.

Let's close this thread :) And thanks again for taking the time.
