Parametric2Array is another simple int32 array for use with the Parametric2Type also for testing a parameterized user-defined extension type that utilizes the parameter for defining different types based on the param.

func (Parametric2Array) ValueStr 

func (a Parametric2Array) ValueStr(i int) string

type Parametric2Type 

type Parametric2Type struct {
	arrow.ExtensionBase
	// contains filtered or unexported fields

func NewParametric2Type 

func NewParametric2Type(p int32) *Parametric2Type

func (Parametric2Type) ArrayType 

func (Parametric2Type) ArrayType() reflect.Type

ArrayType returns TypeOf(Parametric2Array{})

func (Parametric2Type) Deserialize 

func (Parametric2Type) Deserialize(storage arrow.DataType, data string) (arrow.ExtensionType, error)

Deserialize expects storage to be int32 type and data must be a 4 byte little endian slice.

func (*Parametric2Type) ExtensionEquals
