// Retrieves analysis results of Cloud components such as Docker container

// [Grafeas](https://grafeas.io) API.
//
// Analysis results are stored as a series of occurrences. An `Occurrence`
// contains information about a specific analysis instance on a resource. An
// occurrence refers to a `Note`. A note contains details describing the
// analysis and is generally stored in a separate project, called a `Provider`.
// Multiple occurrences can refer to the same note.
//
// For example, an SSL vulnerability could affect multiple images. In this case,
// there would be one note for the vulnerability and an occurrence for each
// image with the vulnerability referring to that note.
