Represents a row key in a Cloud Spanner table or index. A key is a tuple of values constrained to the scalar Cloud Spanner types: currently these are BOOLEAN, INT64, FLOAT64, STRING, BYTES and TIMESTAMP. Values may be null where the table definition permits it.
Key is used to define the row, or endpoints of a range of rows, to retrieve in read operations or to delete in a mutation.
Returns the parts in this key. Each part is represented by the corresponding Cloud Spanner type's canonical Java type, as listed below. Note that other types supported by #of(Object...) are converted to one of the canonical types.
