Functions

Types

type Action

type Annotations_ 

type Annotations_ map[string]string

Instead of copy / pasting the Annotations, SetAnnotations, and the import three lines into every entity that has annotations, the Annotations_ helper type is provided for use in composition. This type is composed without a name so the methods get promoted so they satisfy the HasAnnotations interface.

NOTE(mjs) - The type is exported due to a limitation with go-yaml under 1.6. Once that's fixed it should be possible to make it private again.

NOTE(mjs) - The trailing underscore on the type name is to avoid collisions between the type name and the Annotations method. The underscore can go once the type becomes private again (revert to "annotations").
