Class JsonType
Json type converter.
Use to convert json data between PHP and the database types.
Property Summary
-
$_basicTypes protected static deprecated
arrayList 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|nullIdentifier 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(string|null $name = null)Constructor.
(This method is declared here again so that the inheritance from Cake\Database\Type can be removed in the future.)
Parameters
-
string|null$name optional The name identifying this type
__debugInfo() ¶ public
__debugInfo(): arrayReturns an array that can be used to describe the internal state of this object.
Returns
array_basicTypeCast() ¶ protected
_basicTypeCast(mixed $value): mixedChecks whether this type is a basic one and can be converted using a callback If it is, returns converted value
Parameters
-
mixed$value Value to be converted to PHP equivalent
Returns
mixedboolval() ¶ public static
boolval(mixed $value): boolType converter for boolean values.
Will convert string true/false into booleans.
Parameters
-
mixed$value The value to convert to a boolean.
Returns
boolbuild() ¶ public static
build(string $name): Cake\Database\TypeReturns a Type object capable of converting a type identified by name.
Parameters
-
string$name type identifier
Returns
Cake\Database\TypeThrows
InvalidArgumentExceptionIf type identifier is unknown
buildAll() ¶ public static
buildAll(): arrayReturns an arrays with all the mapped type objects, indexed by name.
Returns
arrayclear() ¶ public static
clear(): voidClears out all created instances and mapped types classes, useful for testing
Returns
voidgetBaseType() ¶ public
getBaseType(): stringReturns 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
stringgetMap() ¶ public static
getMap(string|null $type = null): array|stringCake\Database\TypeInterface|nullGet mapped class name or instance for type(s).
Parameters
-
string|null$type optional Type name to get mapped class for or null to get map array.
Returns
array|stringCake\Database\TypeInterface|nullmanyToPHP() ¶ public
manyToPHP(array $values, array $fields, Cake\Database\Driver $driver): arrayReturns an array of the values converted to the PHP representation of this type.
Parameters
-
array$values -
array$fields -
Cake\Database\Driver$driver
Returns
arraymap() ¶ public static
map(string|string[]Cake\Database\Type[]|null $type = null, stringCake\Database\Type|null $className = null): array|string|nullRegisters 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
-
stringCake\Database\Type|null$className optional The classname or object instance of it to register.
Returns
array|string|nullmarshal() ¶ public
marshal(mixed $value): mixedMarshalls request data into a JSON compatible structure.
Most useful for converting request data into PHP objects, that make sense for the rest of the ORM/Database layers.
Parameters
-
mixed$value The value to convert.
Returns
mixednewId() ¶ public
newId(): mixedGenerate 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
mixedSee Also
