Example 1 with ServiceHttpEndpoint

use of co.cask.cdap.api.service.http.ServiceHttpEndpoint in project cdap by caskdata.

the class ServiceSpecificationCodec method decodeOldSpec.

        // Reconstruct the HttpServiceSpecification. However there is no way to determine the datasets or endpoints
        // as it is not recorded in old spec. It's ok since the spec is only used to load data from MDS during redeploy.
