Threading

[defonion]

Hi,

is there a recommended way to use tt4j with different threads, e.g. charing an instance between the threads or creating a new instance for every thread?

best regards

Hi,

TT4J is not thread-safe. Each TT4J instance talks to one TreeTagger process. If you'd access it from multiple threads, the best thing that could happen is that you'd feed the TreeTagger process with a mix of input from each thread, but its more probably that the whole thing would just crash and burn.

You should create one instance per thread. If you create throw-away threads (a lot of them), you may want your TT4J instance to live longer than an individual thread. In that case, you should try some pooling approach.

Cheers,

Thanks for your fast reply. I think i'll give the pooling approach a try.
