ProxyClient (AWS CloudFormation RPDK Java Plugin 2.0.2 API)

Type Parameters:

ClientT - the AWS client like KinesisClient that is used to invoke the web service
```
public interface ProxyClient<ClientT>
```
This class provides a wrapper for the client and provides methods to inject scoped credentials for each request context when invoking AWS services. This is the primary mechanism for handlers to invoke service requests to ensure the right scoped credentials are being injected. IMPORTANT: DO NOT DIRECTLY INVOKE methods on the client. Use the client to provide method references to be invoked. See example below CreateStreamResponse call(ProxyClient<KinesisClient> client, CreateStreamRequest request) { return client.injectCredentialsAndInvokeV2( request, client.client()::createStream); // method reference }
