public abstract class CdpClient extends Object
Abstract base class for all API client classes. This should not be referenced directly. All subclasses of this class are intended to be generated code and are safe to share across threads. Each CdpClient instance has a dedicated HTTP connection pool used to back its requests. The properties of that pool are configured per-CdpClient using the CdpClientConfiguration passed at creation time. This class is not thread-safe.
