Class EnvironmentsClient (4.6.0)

public class EnvironmentsClient implements BackgroundResource

Service Description: Service for managing Environments.

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 for illustrative purposes only.
 // It may require modifications to work in your environment.
 try (EnvironmentsClient environmentsClient = EnvironmentsClient.create()) {
   GetEnvironmentRequest request =
       GetEnvironmentRequest.newBuilder()
           .setName(
               EnvironmentName.ofProjectEnvironmentName("[PROJECT]", "[ENVIRONMENT]").toString())
           .build();
   Environment response = environmentsClient.getEnvironment(request);
 }
 

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

The surface of this class includes several types of Java methods for each of the API's methods:

  1. A "flattened" method. With this type of method, the fields of the request type have been converted into function parameters. It may be the case that not all fields are available as parameters, and not every API method will have a flattened method entry point.
  2. A "request object" method. This type of method only takes one parameter, a request object, which must be constructed before the call. Not every API method will have a request object method.
  3. A "callable" method. This type of method takes no parameters and returns an immutable API callable object, which can be used to initiate calls to the service.

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 EnvironmentsSettings to create(). For example:

To customize credentials:


 // This snippet has been automatically generated for illustrative purposes only.
 // It may require modifications to work in your environment.
 EnvironmentsSettings environmentsSettings =
     EnvironmentsSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 EnvironmentsClient environmentsClient = EnvironmentsClient.create(environmentsSettings);
 

To customize the endpoint:


 // This snippet has been automatically generated for illustrative purposes only.
 // It may require modifications to work in your environment.
 EnvironmentsSettings environmentsSettings =
     EnvironmentsSettings.newBuilder().setEndpoint(myEndpoint).build();
 EnvironmentsClient environmentsClient = EnvironmentsClient.create(environmentsSettings);

updateEnvironment(UpdateEnvironmentRequest request)

public final Environment updateEnvironment(UpdateEnvironmentRequest request)

Updates the specified agent environment.

This method allows you to deploy new agent versions into the environment. When an environment is pointed to a new agent version by setting environment.agent_version, the environment is temporarily set to the LOADING state. During that time, the environment keeps on serving the previous version of the agent. After the new agent version is done loading, the environment is set back to the RUNNING state. You can use "-" as Environment ID in environment name to update version in "draft" environment. WARNING: this will negate all recent changes to draft and can't be undone. You may want to save the draft to a version before calling this function.

Sample code:


 // This snippet has been automatically generated for illustrative purposes only.
 // It may require modifications to work in your environment.
 try (EnvironmentsClient environmentsClient = EnvironmentsClient.create()) {
   UpdateEnvironmentRequest request =
       UpdateEnvironmentRequest.newBuilder()
           .setEnvironment(Environment.newBuilder().build())

           .setAllowLoadToDraftAndDiscardChanges(true)
           .build();
   Environment response = environmentsClient.updateEnvironment(request);
 }
 
Parameter
