GoogleAdsResponseMetadata (google-ads 17.0.1 API)

java.lang.Object
- com.google.api.gax.grpc.GrpcResponseMetadata
- - com.google.ads.googleads.lib.GoogleAdsResponseMetadata

All Implemented Interfaces:

com.google.api.gax.grpc.ResponseMetadataHandler
```
public class GoogleAdsResponseMetadata
extends com.google.api.gax.grpc.GrpcResponseMetadata
```
GoogleAdsResponseMetadata is used to access the response metadata returned by a Google Ads RPC.
NOTE: the GoogleAdsResponseMetadata class is not thread-safe and should NOT be re-used for multiple calls. A new instance of GoogleAdsResponseMetadata should be constructed for each call that requires metadata to be accessed.
Example usage:
```
 
 GoogleAdsResponseMetadata metadata = new GoogleAdsResponseMetadata();
 Foo foo = client.getFooCallable().call(getFooRequest, metadata.createContextWithHandlers());
 System.out.println("Request id: " + metadata.getRequestId());
 
 
```
