The Cloud Data Loss Prevention (DLP) API is a service that allows clients to detect the presence of Personally Identifiable Information (PII) and other privacy-sensitive data in user-supplied, unstructured data streams, like text blocks or images.
The returned connection object should not be used directly; instead it should be passed as an argument to the constructor ofDlpServiceClient.
The optionaloptionsargument may be used to configure aspects of the returnedDlpServiceConnection. Expected options are any of the types in the following option lists:
