 | // Package containeranalysis is an auto-generated package for the | 
 | // Container Analysis API. | 
 | // | 
 | // An implementation of the Grafeas API, which stores, and enables querying | 
 | // and retrieval of critical metadata about all of your software artifacts. | 
 | // | 
 | //   NOTE: This package is in beta. It is not stable, and may be subject to changes. | 
 | // | 
 | // Use of Context | 
 | // | 
 | // The ctx passed to NewClient is used for authentication requests and | 
 | // for creating the underlying connection, but is not used for subsequent calls. | 
 | // Individual methods on the client use the ctx given to them. | 
 | // | 
 | // To close the open connection, use the Close() method. | 
 | // | 
 | // For information about setting deadlines, reusing contexts, and more | 
 | // please visit godoc.org/cloud.google.com/go. |
