Interface ValueProvider

base/runtime/provider.go:28–39

ValueProvider provides access to a runtime-computed database record.

	// ValueProvider provides access to a runtime-computed
	// database record.
	ValueProvider interface {
		// Set is called when the value is set from outside.
		// If the runtime value is considered read-only ErrReadOnly
		// should be returned. It is guaranteed that the key of
		// the record passed to Set is prefixed with the key used
		// to register the value provider.
		Set(r record.Record) (record.Record, error)
		// Get should return one or more records that match keyOrPrefix.
		// keyOrPrefix is guaranteed to be at least the prefix used to
		// register the ValueProvider.
		Get(keyOrPrefix string) ([]record.Record, error)
	}

	// SimpleValueSetterFunc is a convenience type for implementing a
	// write-only value provider.
