Service Description: A service for retrieving relevant contexts.

This class provides the ability to make remote calls to the backing service through method calls that map to API methods. Sample code to get started:

 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 try (VertexRagServiceClient vertexRagServiceClient = VertexRagServiceClient.create()) {
   LocationName parent = LocationName.of("[PROJECT]", "[LOCATION]");
   RagQuery query = RagQuery.newBuilder().build();
   RetrieveContextsResponse response = vertexRagServiceClient.retrieveContexts(parent, query);
 }
 

Note: close() needs to be called on the VertexRagServiceClient object to clean up resources such as threads. In the example above, try-with-resources is used, which automatically calls close().

Methods

Method	Description	Method Variants
RetrieveContexts	Retrieves relevant contexts for a query.	Request object method variants only take one parameter, a request object, which must be constructed before the call. retrieveContexts(RetrieveContextsRequest request) "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method. retrieveContexts(LocationName parent, RagQuery query) retrieveContexts(String parent, RagQuery query) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. retrieveContextsCallable()
ListLocations	Lists information about the supported locations for this service.	Request object method variants only take one parameter, a request object, which must be constructed before the call. listLocations(ListLocationsRequest request) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. listLocationsPagedCallable() listLocationsCallable()
GetLocation	Gets information about a location.	Request object method variants only take one parameter, a request object, which must be constructed before the call. getLocation(GetLocationRequest request) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. getLocationCallable()
SetIamPolicy	Sets the access control policy on the specified resource. Replacesany existing policy. Can return NOT_FOUND, INVALID_ARGUMENT, and PERMISSION_DENIEDerrors.	Request object method variants only take one parameter, a request object, which must be constructed before the call. setIamPolicy(SetIamPolicyRequest request) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. setIamPolicyCallable()
GetIamPolicy	Gets the access control policy for a resource. Returns an empty policyif the resource exists and does not have a policy set.	Request object method variants only take one parameter, a request object, which must be constructed before the call. getIamPolicy(GetIamPolicyRequest request) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. getIamPolicyCallable()
TestIamPermissions	Returns permissions that a caller has on the specified resource. If theresource does not exist, this will return an empty set ofpermissions, not a NOT_FOUND error. Note: This operation is designed to be used for buildingpermission-aware UIs and command-line tools, not for authorizationchecking. This operation may "fail open" without warning.	Request object method variants only take one parameter, a request object, which must be constructed before the call. testIamPermissions(TestIamPermissionsRequest request) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. testIamPermissionsCallable()

See the individual methods for example code.

Many parameters require resource names to be formatted in a particular way. To assist with these names, this class includes a format method for each type of name, and additionally a parse method to extract the individual identifiers contained within names that are returned.

This class can be customized by passing in a custom instance of VertexRagServiceSettings to create(). For example:

To customize credentials:

 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 VertexRagServiceSettings vertexRagServiceSettings =
     VertexRagServiceSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 VertexRagServiceClient vertexRagServiceClient =
     VertexRagServiceClient.create(vertexRagServiceSettings);
 

To customize the endpoint:

 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 VertexRagServiceSettings vertexRagServiceSettings =
     VertexRagServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
 VertexRagServiceClient vertexRagServiceClient =
     VertexRagServiceClient.create(vertexRagServiceSettings);
