示例1: appendArchives
// appendArchives collects all matching Juju GUI archive metadata information.
func appendArchives(
source simplestreams.DataSource,
matchingItems []interface{},
items map[string]interface{},
cons simplestreams.LookupConstraint,
) ([]interface{}, error) {
var majorVersion int
if guiConstraint, ok := cons.(*constraint); ok {
majorVersion = guiConstraint.majorVersion
}
for _, item := range items {
meta := item.(*Metadata)
if majorVersion != 0 && majorVersion != meta.JujuMajorVersion {
continue
}
fullPath, err := source.URL(meta.Path)
if err != nil {
return nil, errors.Annotate(err, "cannot retrieve metadata full path")
}
meta.FullPath = fullPath
vers, err := version.Parse(meta.StringVersion)
if err != nil {
return nil, errors.Annotate(err, "cannot parse metadata version")
}
meta.Version = vers
meta.Source = source
matchingItems = append(matchingItems, meta)
}
return matchingItems, nil
}示例2: appendMatchingFunc
func appendMatchingFunc(source simplestreams.DataSource, matchingImages []interface{},
images map[string]interface{}, cons simplestreams.LookupConstraint) ([]interface{}, error) {
for _, val := range images {
file := val.(*OvaFileMetadata)

}
}

}示例3: appendMatchingTools
// appendMatchingTools updates matchingTools with tools metadata records from tools which belong to the
// specified series. If a tools record already exists in matchingTools, it is not overwritten.

tools map[string]interface{}, cons simplestreams.LookupConstraint) ([]interface{}, error) {
