Array of visited objects; used to prevent cycling.

Methods

Constructor __construct (line 46)

Constructor

Zend_Json_Encoder __construct ()

encode (line 56)

Use the JSON encoding scheme for the value specified

return: The encoded value
static:
access: public

string encode (mixed $value)

mixed $value: value the object to be encoded

encodeClass (line 346)

Encodes the given $className into the class2 model of encoding PHP classes into JavaScript class2 classes.

NOTE: Currently only public methods and variables are proxied onto the client machine

return: The class2 (JavaScript) encoding of the class
access: public
static:
throws: Zend_Json_Exception

string encodeClass ($className $className, [$package $package = ''])

$className $className: string The name of the class, the class must be instantiable using a null constructor
$package $package: string Optional package name appended to JavaScript proxy class name

encodeClasses (line 369)

Encode several classes at once

Returns JSON encoded classes, using encodeClass().

access: public
static:

string encodeClasses (array $classNames, [string $package = ''])

array $classNames
string $package

_encodeArray (line 153)

JSON encode an array value

Recursively encodes each value of an array and returns a JSON encoded array string.

access: protected

string _encodeArray ($array &$array)

$array &$array: array

_encodeDatum (line 177)

JSON encode a basic data type (string, number, boolean, null)

If value type is not a string, number, boolean, or null, the string 'NULL' is returned.

access: protected

string _encodeDatum ($value &$value)

$value &$value: mixed

_encodeObject (line 101)

Encode an object to JSON by encoding each of the public properties

A special property is added to the JSON object called '__className' that contains the name of the class of $value. This is used to decode the object on the client into a specific class.

access: protected
throws: Zend_Json_Exception

string _encodeObject ($value &$value)

$value &$value: object

_encodeString (line 199)

JSON encode a string value by escaping characters as necessary

access: protected

string _encodeString ($value &$string)

$value &$string: string

_encodeValue (line 77)

Recursive driver which determines the type of value to be encoded

and then dispatches to the appropriate method. $values are either

objects (returns from _encodeObject())
arrays (returns from _encodeArray())
basic datums (e.g. numbers or strings) (returns from _encodeDatum())

return: Encoded value
access: protected

string _encodeValue ($value &$value)

$value &$value: mixed The value to be encoded

_wasVisited (line 134)

Determine if an object has been serialized already

access: protected

boolean _wasVisited (mixed &$value)

mixed $value
