Functions

func Create

func Create(objectType string, attributes []string) string

Create combines the given `attributes` to form a composite key. The objectType and attributes are expected to have only valid utf8 strings and should not contain U+0000 (nil byte) and U+10FFFF (biggest and unallocated code point). The resulting composite key can be used as the key in PutState().

func CreateRangeKeysForPartialCompositeKey

func CreateRangeKeysForPartialCompositeKey(objectType string, attributes []string) (string, string)

CreateRangeKeysForPartialCompositeKey returns a start and an end key for the given partial composite key

func Split

func Split(compositeKey string) (string, []string)

Split splits the specified key into attributes on which the composite key was formed. Composite keys found during range queries or partial composite key queries can therefore be split into their composite parts.
