Functions

func Version

func Version() string

returns the current implementation version

Types

type Json

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

func New

func New() *Json

New returns a pointer to a new, empty `Json` object

func NewFromAny

func NewFromAny(data interface{}) *Json

New returns a pointer to a new, empty `Json` object

func NewFromReader

func NewFromReader(r io.Reader) (*Json, error)

NewFromReader returns a *Json by decoding from an io.Reader

func NewJson

func NewJson(body []byte) (*Json, error)

NewJson returns a pointer to a new `Json` object after unmarshaling `body` bytes

func (*Json) Array

func (j *Json) Array() ([]interface{}, error)

Array type asserts to an `array`

func (*Json) Bool

func (j *Json) Bool() (bool, error)

Bool type asserts to `bool`

func (*Json) Bytes

func (j *Json) Bytes() ([]byte, error)

Bytes type asserts to `[]byte`

func (*Json) CheckGet

func (j *Json) CheckGet(key string) (*Json, bool)

CheckGet returns a pointer to a new `Json` object and a `bool` identifying success or failure

useful for chained operations when success is important:

if data, ok := js.Get("top_level").CheckGet("inner"); ok {
    log.Println(data)
}

func (*Json) Del

func (j *Json) Del(key string)

Del modifies `Json` map by deleting `key` if it is present.

func (*Json) Encode

func (j *Json) Encode() ([]byte, error)

Encode returns its marshaled data as `[]byte`

func (*Json) EncodePretty

func (j *Json) EncodePretty() ([]byte, error)

EncodePretty returns its marshaled data as `[]byte` with indentation

func (*Json) Float64

func (j *Json) Float64() (float64, error)

Float64 coerces into a float64

func (*Json) FromDB

func (j *Json) FromDB(data []byte) error

func (*Json) Get

func (j *Json) Get(key string) *Json

Get returns a pointer to a new `Json` object for `key` in its `map` representation

useful for chaining operations (to traverse a nested JSON):

js.Get("top_level").Get("dict").Get("value").Int()

func (*Json) GetIndex

func (j *Json) GetIndex(index int) *Json

GetIndex returns a pointer to a new `Json` object for `index` in its `array` representation

this is the analog to Get when accessing elements of a json array instead of a json object:

js.Get("top_level").Get("array").GetIndex(1).Get("key").Int()

func (*Json) GetPath

func (j *Json) GetPath(branch ...string) *Json

GetPath searches for the item as specified by the branch without the need to deep dive using Get()'s.

js.GetPath("top_level", "dict")

func (*Json) Int

func (j *Json) Int() (int, error)

Int coerces into an int

func (*Json) Int64

func (j *Json) Int64() (int64, error)

Int64 coerces into an int64

func (*Json) Interface

func (j *Json) Interface() interface{}

Interface returns the underlying data

func (*Json) Map

func (j *Json) Map() (map[string]interface{}, error)

Map type asserts to `map`

func (*Json) MarshalJSON

func (j *Json) MarshalJSON() ([]byte, error)

Implements the json.Marshaler interface.

func (*Json) MustArray

func (j *Json) MustArray(args ...[]interface{}) []interface{}

MustArray guarantees the return of a `[]interface{}` (with optional default)

useful when you want to iterate over array values in a succinct manner:

for i, v := range js.Get("results").MustArray() {
	fmt.Println(i, v)
}

func (*Json) MustBool

func (j *Json) MustBool(args ...bool) bool

MustBool guarantees the return of a `bool` (with optional default)

useful when you explicitly want a `bool` in a single value return context:

myFunc(js.Get("param1").MustBool(), js.Get("optional_param").MustBool(true))

func (*Json) MustFloat64

func (j *Json) MustFloat64(args ...float64) float64

MustFloat64 guarantees the return of a `float64` (with optional default)

useful when you explicitly want a `float64` in a single value return context:

myFunc(js.Get("param1").MustFloat64(), js.Get("optional_param").MustFloat64(5.150))

func (*Json) MustInt

func (j *Json) MustInt(args ...int) int

MustInt guarantees the return of an `int` (with optional default)

useful when you explicitly want an `int` in a single value return context:

myFunc(js.Get("param1").MustInt(), js.Get("optional_param").MustInt(5150))

func (*Json) MustInt64

func (j *Json) MustInt64(args ...int64) int64

MustInt64 guarantees the return of an `int64` (with optional default)

useful when you explicitly want an `int64` in a single value return context:

myFunc(js.Get("param1").MustInt64(), js.Get("optional_param").MustInt64(5150))

func (*Json) MustMap

func (j *Json) MustMap(args ...map[string]interface{}) map[string]interface{}

MustMap guarantees the return of a `map[string]interface{}` (with optional default)

useful when you want to iterate over map values in a succinct manner:

for k, v := range js.Get("dictionary").MustMap() {
	fmt.Println(k, v)
}

func (*Json) MustString

func (j *Json) MustString(args ...string) string

MustString guarantees the return of a `string` (with optional default)

useful when you explicitly want a `string` in a single value return context:

myFunc(js.Get("param1").MustString(), js.Get("optional_param").MustString("my_default"))

func (*Json) MustStringArray

func (j *Json) MustStringArray(args ...[]string) []string

MustStringArray guarantees the return of a `[]string` (with optional default)

useful when you want to iterate over array values in a succinct manner:

for i, s := range js.Get("results").MustStringArray() {
	fmt.Println(i, s)
}

func (*Json) MustUint64

func (j *Json) MustUint64(args ...uint64) uint64

MustUInt64 guarantees the return of an `uint64` (with optional default)

useful when you explicitly want an `uint64` in a single value return context:

myFunc(js.Get("param1").MustUint64(), js.Get("optional_param").MustUint64(5150))

func (*Json) SetPath

func (j *Json) SetPath(branch []string, val interface{})

SetPath modifies `Json`, recursively checking/creating map keys for the supplied path, and then finally writing in the value

func (*Json) String

func (j *Json) String() (string, error)

String type asserts to `string`

func (*Json) StringArray

func (j *Json) StringArray() ([]string, error)

StringArray type asserts to an `array` of `string`
