* Transforms a value from the original representation to a transformed representation.
*
* This method is called on two occasions inside a form field:
*
* 1. When the form field is initialized with the data attached from the datasource (object or array).
* 2. When data from a request is bound using {@link Form::bind()} to transform the new input data
* back into the renderable format. For example if you have a date field and bind '2009-10-10' onto
* it you might accept this value because its easily parsed, but the transformer still writes back
* "2009/10/10" onto the form field (for further displaying or other purposes).
*
* This method must be able to deal with empty values. Usually this will
* be NULL, but depending on your implementation other empty values are
* possible as well (such as empty strings). The reasoning behind this is
* that value transformers must be chainable. If the transform() method
* of the first value transformer outputs NULL, the second value transformer
* must be able to process that value.
*
* By convention, transform() should return an empty string if NULL is
* passed.
*
* @param mixed $value The value in the original representation
*
* @return mixed The value in the transformed representation
*
* @throws TransformationFailedException When the transformation fails.
