PipelineOptions JSON command line argument

[Shen Li]

Hi,

I am trying to understand how can I extend PipelineOptions to add getters
and setters with my custom type. The document in PiplineOptionsFactory says
"JSON format is required for all other types". If I want to use
java.util.logging.Level in a getter and a setter, what JSON string should I
pass in the command line?

Thanks,

Shen
