getPrimitiveRepresentation()

ILIAS\Data\Description\DObject::getPrimitiveRepresentation

(

mixed

$data

)

Each of the types that can be described has a canonical representation created from primitive PHP types.

This attempts to transform the provided data into such a representation.

If this returns a \Closure, the data cannot be transformed into such a representation and the \Closure will produce a generator that provides a list of defects where $data does not match the description. If this does return something else it will be plain old php data according to the description.

Reimplemented from ILIAS\Data\Description\Description.
