i'm relatively new protobufs , wondering how use process list of structures.
lets have configuration file looks this:
bucket{ name = "a"; path = "~/document/..."; traffic = 5; } bucket{ name = "b"; path = "~/document/..."; traffic = 6; } bucket{ name = "c"; path = "~/document/..."; traffic = 7; } etc etc.
so using protobuf structure ease of use later in java. i'm trying make map in map (a protobuf find correct bucket, , map obtain member attributes inside bucket).
option java_outer_classname = "buckets"; message bucket { required string name = 1; required string path = 2; optional int32 traffic = 3; } message bucketlist { required bucket bucket = 1; } i'm confused on how link two, in, how pass configuration file protobuf methods (after compiles java class) , use to access bucket member stuff path bucket name a?
thank you!
you've got wrong idea of protobuf used for, data interchange library means used encode , exchange data between programs. never meant used configuration , doesn't have way read text-based definition of data since deals binary files.
looking @ config format have 2 options:
- the format you've chosen looks lot hocon, https://github.com/typesafehub/config should able read , provide readable config object small amount of editing.
- if want type-safe config (defining structure of config actual java object) need use other format supports deserialization object. json configuration can read objects using libraries https://github.com/google/gson or https://github.com/fasterxml/jackson
