public __construct(array $transformers)

Uses the given value transformers to transform values.

public mixed transform(mixed $value)

Passes the value through the transform() method of all nested transformers.

Passes the value through the reverseTransform() method of all nested transformers.

The transformers receive the value in the reverse order as they were passed to the constructor. Each transformer receives the result of the previous transformer as input. The output of the last transformer is returned by this method.
