Types

type Var

type Var struct {
	// contains filtered or unexported fields
}

func New

func New(value interface{}, unsafe ...bool) *Var

New returns a new Var with given <value>. The param <unsafe> used to specify whether using Var in un-concurrent-safety, which is false in default, means concurrent-safe.

func (*Var) Bool

func (v *Var) Bool() bool

func (*Var) Bytes

func (v *Var) Bytes() []byte

func (*Var) Duration

func (v *Var) Duration() time.Duration

TimeDuration converts and returns <v> as time.Duration. If value of <v> is string, then it uses time.ParseDuration for conversion.

func (*Var) Float32

func (v *Var) Float32() float32

func (*Var) Float64

func (v *Var) Float64() float64

func (*Var) Floats

func (v *Var) Floats() []float64

func (*Var) GTime

func (v *Var) GTime(format ...string) *gtime.Time

GTime converts and returns <v> as *gtime.Time. The param <format> specifies the format of the time string using gtime, eg: Y-m-d H:i:s.

func (*Var) Int

func (v *Var) Int() int

func (*Var) Int16

func (v *Var) Int16() int16

func (*Var) Int32

func (v *Var) Int32() int32

func (*Var) Int64

func (v *Var) Int64() int64

func (*Var) Int8

func (v *Var) Int8() int8

func (*Var) Interface

func (v *Var) Interface() interface{}

See Val().

func (*Var) Interfaces

func (v *Var) Interfaces() []interface{}

func (*Var) Ints

func (v *Var) Ints() []int

func (*Var) IsNil

func (v *Var) IsNil() bool

func (*Var) Set

func (v *Var) Set(value interface{}) (old interface{})

Set sets <value> to <v>, and returns the old value.

func (*Var) String

func (v *Var) String() string

func (*Var) Strings

func (v *Var) Strings() []string

func (*Var) Struct

func (v *Var) Struct(objPointer interface{}, attrMapping ...map[string]string) error

Struct maps value of <v> to <objPointer>. The param <objPointer> should be a pointer to a struct instance. The param <attrMapping> is used to specify the key-to-attribute mapping rules.

func (*Var) Time

func (v *Var) Time(format ...string) time.Time

Time converts and returns <v> as time.Time. The param <format> specifies the format of the time string using gtime, eg: Y-m-d H:i:s.

func (*Var) Uint

func (v *Var) Uint() uint

func (*Var) Uint16

func (v *Var) Uint16() uint16

func (*Var) Uint32

func (v *Var) Uint32() uint32

func (*Var) Uint64

func (v *Var) Uint64() uint64

func (*Var) Uint8

func (v *Var) Uint8() uint8

func (*Var) Val

func (v *Var) Val() interface{}

Val returns the current value of <v>.
