Class JsonType

Json type converter.

Use to convert json data between PHP and the database types.

Namespace: Cake\Database\Type

Properties summary

  • $_basicTypes protected static
    array

    List of basic type mappings, used to avoid having to instantiate a class for doing conversion on these.

  • $_builtTypes protected static
    \Cake\Database\Type[]

    Contains a map of type object instances to be reused if needed.

  • $_name protected
    string|null

    Identifier name for this type.

  • $_types protected static
    string[]|\Cake\Database\Type[]

    List of supported database types. A human readable identifier is used as key and a complete namespaced class name as value representing the class that will do actual type conversions.

Method Detail

__construct() public 

__construct(mixed $name)

Constructor.

(This method is declared here again so that the inheritance from Cake\Database\Type can be removed in the future.)

Parameters

string|null $name optional

The name identifying this type

__debugInfo() public 

__debugInfo()

Returns an array that can be used to describe the internal state of this object.

Returns

array

_basicTypeCast() protected 

_basicTypeCast(mixed $value)

Checks whether this type is a basic one and can be converted using a callback If it is, returns converted value

Parameters

mixed $value

Value to be converted to PHP equivalent

Returns

mixed

boolval() public static 

boolval(mixed $value)

Type converter for boolean values.

Will convert string true/false into booleans.

Parameters

mixed $value

The value to convert to a boolean.

Returns

bool

build() public static 

build(mixed $name)

Returns a Type object capable of converting a type identified by name.

Parameters

string $name

type identifier

Returns

\Cake\Database\Type

Throws

InvalidArgumentException
If type identifier is unknown

buildAll() public static 

buildAll()

Returns an arrays with all the mapped type objects, indexed by name.

Returns

array

clear() public static 

clear()

Clears out all created instances and mapped types classes, useful for testing

getBaseType() public 

getBaseType()

Returns the base type name that this class is inheriting.

This is useful when extending base type for adding extra functionality, but still want the rest of the framework to use the same assumptions it would do about the base type it inherits from.

Returns

string

The base type name that this class is inheriting.

getMap() public static 

getMap(mixed $type)

Get mapped class name or instance for type(s).

Parameters

string|null $type optional

Type name to get mapped class for or null to get map array.

Returns

array|string|\Cake\Database\TypeInterface|null

Configured class name or instance for give $type or map array.

getName() public 

getName()

Returns type identifier name for this object.

Returns

string

The type identifier name for this object.

manyToPHP() public 

manyToPHP(array $values, array $fields, \Cake\Database\Driver $driver)

Returns an array of the values converted to the PHP representation of this type.

Parameters

array $values

The original array of values containing the fields to be casted

string[] $fields

The field keys to cast

\Cake\Database\Driver $driver

Object from which database preferences and configuration will be extracted.

Returns

array

map() public static 

map(mixed $type, mixed $className)

Registers a new type identifier and maps it to a fully namespaced classname, If called with no arguments it will return current types map array If $className is omitted it will return mapped class for $type

Deprecated 3.6.2:

  • The usage of $type as string[]|\Cake\Database\Type[] is deprecated. Use Type::setMap() with string[] instead.
  • Passing $className as \Cake\Database\Type instance is deprecated, use class name string only.
  • Using this method as getter is deprecated. Use Type::getMap() instead.

Parameters

string|string[]|\Cake\Database\Type[]|null $type optional

If string name of type to map, if array list of arrays to be mapped

string|\Cake\Database\Type|null $className optional

The classname or object instance of it to register.

Returns

array|string|null

If $type is null then array with current map, if $className is null string configured class name for give $type, null otherwise

marshal() public 

marshal(mixed $value)

Marshals request data into a JSON compatible structure.

Parameters

mixed $value

The value to convert.

Returns

mixed

Converted value.

newId() public 

newId()

Generate a new primary key value for a given type.

This method can be used by types to create new primary key values when entities are inserted.

Returns

mixed

A new primary key value.
