Methods

__construct

Constructor.

Parameters
NameDescription
data array

Optional. Data for populating the Message object.

↳ code int

Required. The TypeCode for this type.

↳ array_element_type Google\Cloud\Spanner\V1\Type

If code == ARRAY, then array_element_type is the type of the array elements.

↳ struct_type Google\Cloud\Spanner\V1\StructType

If code == STRUCT, then struct_type provides type information for the struct's fields.

↳ type_annotation int

The TypeAnnotationCode that disambiguates SQL type that Spanner will use to represent values of this type during query processing. This is necessary for some type codes because a single TypeCode can be mapped to different SQL types depending on the SQL dialect. type_annotation typically is not needed to process the content of a value (it doesn't affect serialization) and clients can ignore it on the read path.

getCode

Returns
