Functions

func Decode 

func Decode(data interface{}) (interface{}, error)

Decode decodes <data>(string/[]byte) to golang variable.

func DecodeTo 

func DecodeTo(data interface{}, v interface{}) error

Decode decodes <data>(string/[]byte) to specified golang variable <v>. The <v> should be a pointer type.

func Encode 

func Encode(value interface{}) ([]byte, error)

Encode encodes <value> to JSON data type of bytes.

func Valid 

func Valid(data interface{}) bool

Valid checks whether <data> is a valid JSON data type.

Types

type Json 

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

The customized JSON struct.

func DecodeToJson 

func DecodeToJson(data interface{}, unsafe ...bool) (*Json, error)

DecodeToJson codes <data>(string/[]byte) to a Json object.

func Load 

func Load(path string, unsafe ...bool) (*Json, error)

Load loads content from specified file <path>, and creates a Json object from its content.

func LoadContent 

func LoadContent(data interface{}, unsafe ...bool) (*Json, error)

LoadContent creates a Json object from given content, it checks the data type of <content> automatically, supporting JSON, XML, YAML and TOML types of data.

func New 

func New(data interface{}, unsafe ...bool) *Json

New creates a Json object with any variable type of <data>, but <data> should be a map or slice for data access reason, or it will make no sense. The <unsafe> param specifies whether using this Json object in un-concurrent-safe context, which is false in default.

func NewUnsafe 

func NewUnsafe(data ...interface{}) *Json

NewUnsafe creates a un-concurrent-safe Json object.

func (*Json) Append 

func (j *Json) Append(pattern string, value interface{}) error

We can also access slice item by its index number in <pattern>, eg: "items.name.first", "list.10".

It returns a default value specified by <def> if value for <pattern> is not found.

func (*Json) GetJsons 

func (j *Json) GetJsons(pattern string, def ...interface{}) []*Json

GetJsons gets the value by specified <pattern>, and converts it to a slice of Json object.

func (*Json) GetMap 

func (j *Json) GetMap(pattern string, def ...interface{}) map[string]interface{}
