Interface MultiIndexer

index.go:44–49

MultiIndexer is an interface used for defining indexes that generate multiple values per object. Each value is stored as a seperate index pointing to the same object. For example, an index that extracts the first and last name of a person and allows lookup based on eitherd would be a MultiIndexer.

// of this example would split the first and last name and return both as
// values.
type MultiIndexer interface {
	// FromObject extracts index values from an object. The return values
	// are the same as a SingleIndexer except there can be multiple index
	// values.
	FromObject(raw interface{}) (bool, [][]byte, error)
}

// PrefixIndexer is an optional interface on top of an Indexer that allows
// indexes to support prefix-based iteration.
