Package com.google.api.gax.grpc

Class GrpcCallContext

java.lang.Object

com.google.api.gax.grpc.GrpcCallContext

All Implemented Interfaces:

RetryingContext, ApiCallContext

@BetaApi("Reference ApiCallContext instead - this class is likely to experience breaking changes")
public final class GrpcCallContext
extends Object
implements ApiCallContext

GrpcCallContext encapsulates context data used to make a grpc call.

GrpcCallContext is immutable in the sense that none of its methods modifies the GrpcCallContext itself or the underlying data. Methods of the form withX, such as withTransportChannel(com.google.api.gax.rpc.TransportChannel), return copies of the object, but with one field changed. The immutability and thread safety of the arguments solely depends on the arguments themselves.
