// NewDecoder creates a new instance of the extended JSON Decoder.
func NewDecoder(r io.Reader) *Decoder { … }

// SeekTo causes the Decoder to move forward to a given path in the JSON structure.
//
// The path argument must consist of strings or integers. Each string specifies an JSON object key, and
// each integer specifies an index into a JSON array.
//
// Consider the JSON structure
//
//  { "a": [0,"s",12e4,{"b":0,"v":35} ] }
//
// SeekTo("a",3,"v") will move to the value referenced by the "a" key in the current object,
// followed by a move to the 4th value (index 3) in the array, followed by a move to the value at key "v".
// In this example, a subsequent call to the decoder's Decode() would unmarshal the value 35.
//
// SeekTo returns a boolean value indicating whether a match was found.
//
// Decoder is intended to be used with a stream of tokens. As a result it navigates forward only.
func (d *Decoder) SeekTo(path ...interface{ … }

// Decode reads the next JSON-encoded value from its input and stores it in the value pointed to by v. This is
// equivalent to encoding/json.Decode().

// Path returns a slice of string and/or int values representing the path from the root of the JSON object to the
// position of the most-recently parsed token.
func (d *Decoder) Path() JsonPath { … }

// Token is equivalent to the Token() method on json.Decoder. The primary difference is that it distinguishes
// between strings that are keys and and strings that are values. String tokens that are object keys are returned as a
// KeyString rather than as a native string.
func (d *Decoder) Token() (json.Token, error) { … }

// Scan moves forward over the JSON stream consuming all the tokens at the current level (current object, current array)
// invoking each matching PathAction along the way.
//
// Scan returns true if there are more contiguous values to scan (for example in an array).
