Method Details

buildPropertyMappingConfiguration() public method

Builds the default property mapping configuration.

public buildPropertyMappingConfiguration ( string $type = PropertyMappingConfiguration::class ) : PropertyMappingConfiguration
$type	string	the implementation class name of the PropertyMappingConfiguration to instantiate; must be a subclass of Neos\Flow\Property\PropertyMappingConfiguration
return	PropertyMappingConfiguration

convert() public method

If $source is an object and already is of type $targetType, we do return the unmodified object.

public convert ( mixed $source, string $targetType, Neos\Flow\Property\PropertyMappingConfigurationInterface $configuration = null ) : mixed
$source	mixed	the source data to map. MUST be a simple type, NO object allowed!
$targetType	string	The type of the target; can be either a class name or a simple type.
$configuration	Neos\Flow\Property\PropertyMappingConfigurationInterface	Configuration for the property mapping. If NULL, the PropertyMappingConfigurationBuilder will create a default configuration.
return	mixed	an instance of $targetType

determineSourceTypes() protected method

Determine the type of the source data, or throw an exception if source was an unsupported format.

protected determineSourceTypes ( mixed $source ) : array
$source	mixed
return	array	Possible source types (single value for simple typed source, multiple values for object source)

doMapping() protected method

Internal function which actually does the property mapping.

protected doMapping ( mixed $source, string $targetType, Neos\Flow\Property\PropertyMappingConfigurationInterface $configuration, array &$currentPropertyPath ) : mixed
$source	mixed	the source data to map. MUST be a simple type, NO object allowed!
$targetType	string	The type of the target; can be either a class name or a simple type.
$configuration	Neos\Flow\Property\PropertyMappingConfigurationInterface	Configuration for the property mapping.
$currentPropertyPath	array	The property path currently being mapped; used for knowing the context in case an exception is thrown.
return	mixed	an instance of $targetType

findEligibleConverterWithHighestPriority() protected method

protected findEligibleConverterWithHighestPriority ( mixed $converters, mixed $source, string $targetType ) : mixed
$converters	mixed
$source	mixed
$targetType	string
return	mixed	Either the matching object converter or NULL

findFirstEligibleTypeConverterInObjectHierarchy() protected method

Tries to find a suitable type converter for the given source and target type.

protected findFirstEligibleTypeConverterInObjectHierarchy ( string $source, string $sourceType, string $targetType ) : mixed
$source	string	The actual source value
$sourceType	string	Type of the source to convert from
$targetType	string	Name of the target type to find a type converter for
return	mixed	Either the matching object converter or NULL

findTypeConverter() protected method

Determine the type converter to be used. If no converter has been found, an exception is raised.

protected findTypeConverter ( mixed $source, string $targetType, Neos\Flow\Property\PropertyMappingConfigurationInterface $configuration ) : Neos\Flow\Property\TypeConverterInterface
$source	mixed
$targetType	string
$configuration	Neos\Flow\Property\PropertyMappingConfigurationInterface
return	Neos\Flow\Property\TypeConverterInterface	Type Converter which should be used to convert between $source and $targetType.

getConvertersForInterfaces() protected method

protected getConvertersForInterfaces ( array $convertersForSource, array $interfaceNames ) : array
$convertersForSource	array
$interfaceNames	array
return	array

getMessages() public method

Get the messages of the last Property Mapping

public getMessages ( ) : Neos\Error\Messages\Result
return	Neos\Error\Messages\Result

getTypeConverterImplementationClassNames() public static method

Returns all class names implementing the TypeConverterInterface.

public static getTypeConverterImplementationClassNames ( Neos\Flow\ObjectManagement\ObjectManagerInterface $objectManager ) : array
$objectManager	Neos\Flow\ObjectManagement\ObjectManagerInterface
return	array	Array of type converter implementations

getTypeConverters() public method

It has the following structure: 1. Dimension: Source Type 2. Dimension: Target Type 3. Dimension: Priority Value: Type Converter instance

public getTypeConverters ( ) : array
return	array

initializeObject() public method

Here, the typeConverter array gets initialized.

public initializeObject ( ) : void
return	void

prepareTypeConverterMap() protected method

Collects all TypeConverter implementations in a multi-dimensional array with source and target types.
