load

public Proto load(String path,
 Proto importer)
           throws Exception

Specified by:

load in interface Proto.Loader

Throws:

Exception

searchFromProtoPathOnly

protected Proto searchFromProtoPathOnly(String path,
 Proto importer)
                                 throws Exception

Search from proto_path only. For full protoc compatibility, use this.

 Enable via:
 -Dproto_path=$path -Dproto_search_strategy=1
 

Throws:
