Types

type Key

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

Key represents either the index of an array (int) or the key in a map (string).

func (Key) Array

func (k Key) Array() int

func (Key) IsArray

func (k Key) IsArray() bool

func (Key) IsMap

func (k Key) IsMap() bool

func (Key) Map

func (k Key) Map() string

type MapTraverser

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

func NewMapTraverser

func NewMapTraverser(m map[string]interface{}) MapTraverser

func (MapTraverser) Child

func (t MapTraverser) Child(keys ...string) MapTraverser

func (MapTraverser) Delete

func (t MapTraverser) Delete(key string) bool

func (MapTraverser) FindAllWithKey

func (t MapTraverser) FindAllWithKey(key string) MapTraversers

func (MapTraverser) Set

func (t MapTraverser) Set(key string, i interface{}) bool

func (MapTraverser) SetAll

func (t MapTraverser) SetAll(fn SetFunc) int

SetAll traverses all []interface{} and map[string]interface{} types and calls the fn (SetFunc) for each key/value pair. If the SetFunc for a given key/value pair returns bool(true) as its 2nd return value, then said value will be updated to whatever SetFunc returned as the interface{}.

func (MapTraverser) Value

func (t MapTraverser) Value(key string, i interface{}) (interface{}, bool)

type MapTraversers

type MapTraversers []MapTraverser

type SetFunc

type SetFunc func(k Key, value interface{}) (interface{}, bool)
