Types

type KeyNotFoundError

type KeyNotFoundError struct {
	Key string
}

func (KeyNotFoundError) Error

func (k KeyNotFoundError) Error() string

type Object

type Object struct {
	Value
	// contains filtered or unexported fields
}

Object represents an object JSON object. It inherets from Value but with an additional method to access a map representation of it's content. It's useful when iterating.

func NewFromMap

func (*Object) GetNumber

func (v *Object) GetNumber(keys ...string) (json.Number, error)

n, err := GetNumber("address", "street_number")

func (*Object) GetNumberArray

func (v *Object) GetNumberArray(keys ...string) ([]json.Number, error)

Gets the value at key path and attempts to typecast the value into an array of numbers. Returns error if the value is not a json array or if any of the contained objects are not numbers. Example:

friendAges, err := GetNumberArray("person", "friend_ages")
for i, friendAge := range friendAges {
	... // friendAge will be of type float64 here
}

func (*Object) GetObject

func (v *Object) GetObject(keys ...string) (*Object, error)

Gets the value at key path and attempts to typecast the value into an object. Returns error if the value is not a json object. Example:

object, err := GetObject("person", "address")

func (*Object) GetObjectArray

func (v *Object) GetObjectArray(keys ...string) ([]*Object, error)

Gets the value at key path and attempts to typecast the value into an array of objects. Returns error if the value is not a json array or if any of the contained objects are not objects. Example:

friends, err := GetObjectArray("person", "friends")
for i, friend := range friends {
	... // friend will be of type Object here
}

func (*Object) GetString

func (v *Object) GetString(keys ...string) (string, error)

Gets the value at key path and attempts to typecast the value into a string. Returns error if the value is not a json string. Example:

string, err := GetString("address", "street")

func (*Object) GetStringArray

func (v *Object) GetStringArray(keys ...string) ([]string, error)

Gets the value at key path and attempts to typecast the value into an array of string. Returns error if the value is not a json array or if any of the contained objects are not strings. Gets the value at key path and attempts to typecast the value into an array of objects. Returns error if the value is not a json array or if any of the contained objects are not objects. Example:

}

func (*Object) GetValue

func (v *Object) GetValue(keys ...string) (*Value, error)

func (v *Object) GetValueArray(keys ...string) ([]*Value, error)

Gets the value at key path and attempts to typecast the value into an array. Returns error if the value is not a json array. Consider using the more specific Get<Type>Array() since it may reduce later type casts. Example:
