Functions

func Elem

func Elem(v reflect.Value) reflect.Value

Elem returns the value that the interface v contains or that the pointer v points to.

func HasChild

func HasChild(v reflect.Value) bool

HasChild check. eg: array, slice, map, struct

func IsEmpty

func IsEmpty(v reflect.Value) bool

IsEmpty reflect value check

func IsEmptyValue

func IsEmptyValue(v reflect.Value) bool

IsEmptyValue reflect value check. From src/pkg/encoding/json/encode.go.

func IsEqual

func IsEqual(src, dst interface{}) bool

IsEqual determines if two objects are considered equal.

TIP: cannot compare function type

func IsFunc

func IsFunc(val interface{}) bool

IsFunc value

func IsNil

func IsNil(v reflect.Value) bool

IsNil reflect value

func Len

func Len(v reflect.Value) int

Len get reflect value length

func SliceSubKind

func SliceSubKind(typ reflect.Type) reflect.Kind

SliceSubKind get sub-elem kind of the array, slice, variadic-var.

Usage:

SliceSubKind(reflect.TypeOf([]string{"abc"})) // reflect.String

Types

type BKind

type BKind uint

BKind base data kind type

func ToBKind

func ToBKind(kind reflect.Kind) BKind

ToBKind convert reflect.Kind to base kind

func ToBaseKind

func ToBaseKind(kind reflect.Kind) BKind

ToBaseKind convert reflect.Kind to base kind

type Type

type Type interface {
	reflect.Type
	// BaseKind value
	BaseKind() BKind
}

Type struct

func TypeOf

func TypeOf(v interface{}) Type

TypeOf value

type Value

type Value struct {
	reflect.Value
	// contains filtered or unexported fields
}

Value struct

func ValueOf

func ValueOf(v interface{}) Value

ValueOf the give value

func Wrap

func Wrap(rv reflect.Value) Value

Wrap the give value

func (Value) BKind

func (v Value) BKind() BKind

BKind value

func (Value) BaseKind

func (v Value) BaseKind() BKind

BaseKind value

func (Value) Elem

func (v Value) Elem() Value

Elem returns the value that the interface v contains or that the pointer v points to.

TIP: not like reflect.Value.Elem. otherwise, will return self.

func (Value) HasChild

func (v Value) HasChild() bool

HasChild check. eg: array, slice, map, struct

func (Value) Indirect

func (v Value) Indirect() Value

Indirect value. alias of the reflect.Indirect()

func (Value) Int

func (v Value) Int() int64

Int value. if is uintX will convert to int64

func (Value) Type

func (v Value) Type() Type

Type of value.

func (Value) Uint

func (v Value) Uint() uint64

Uint value. if is intX will convert to uint64
