mapDateTime()

Creates a DateTime from a unix timestamp or date/datetime/time value.

protected mapDateTime(int|string $value[, string|null $storageFormat = null ][, string $targetType = DateTime::class ]) : DateTimeInterface

If the input is empty, NULL is returned.

mapObjectToClassProperty()

Returns the mapped classProperty from the identityMap or mapResultToPropertyValue()

protected mapObjectToClassProperty(DomainObjectInterface $parentObject, string $propertyName, mixed $fieldValue) : mixed

If the field value is empty and the column map has no parent key field name, the relation will be empty. If the persistence session has a registered object of the correct type and identity (fieldValue), this function returns that object. Otherwise, it proceeds with mapResultToPropertyValue().

Parameters
$parentObject : DomainObjectInterface
$propertyName : string
$fieldValue : mixed

mapResultToPropertyValue()

mapSingleRow()

Maps a single row on an object of the given class

Parameters
$className : string

The name of the target class

$row : array<string|int, mixed>

A single array with field_name => value pairs

Return values
object —

An object of the given class

propertyMapsByForeignKey()

Checks if the relation is based on a foreign key.

protected propertyMapsByForeignKey(DomainObjectInterface $parentObject, string $propertyName) : bool
Parameters
$parentObject : DomainObjectInterface
$propertyName : string
Return values
bool —

TRUE if the property is mapped

resolveRelationValuesOfField()

This resolves relations via RelationHandler and returns their UIDs respectively, and works for MM/ForeignField/CSV in IRRE + Select + Group.

protected resolveRelationValuesOfField(DataMap $dataMap, ColumnMap $columnMap, DomainObjectInterface $parentObject, string $fieldValue, int $workspaceId) : array<string|int, mixed>|false|mixed

Note: This only happens for resolving properties for models. When limiting a parentQuery, the Typo3DbQueryParser is taking care of it.

By using the RelationHandler, the localized, deleted and moved records turn out to be properly resolved without having to build intermediate queries.

This is currently only used in workspaces' context, as it is 1 additional DB query needed.

Parameters
$dataMap : DataMap
$columnMap : ColumnMap
$parentObject : DomainObjectInterface
$fieldValue : string
$workspaceId : int
Return values
array<string|int, mixed>|false|mixed
