DataTransformerChain

class DataTransformerChain implements DataTransformerInterface

Passes a value through multiple value transformers.

Methods

	__construct(array $transformers) Uses the given value transformers to transform values.
mixed	transform(mixed $value) Passes the value through the transform() method of all nested transformers.
mixed	reverseTransform(mixed $value) Passes the value through the reverseTransform() method of all nested transformers.
DataTransformerInterface[]	getTransformers()

Details

__construct(array $transformers)

Uses the given value transformers to transform values.

Parameters

array

$transformers

mixed transform(mixed $value)

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

The transformers receive the value in the same 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.

Parameters

mixed

$value

The value in the original representation

Return Value

mixed

The value in the transformed representation

Exceptions

TransformationFailedException

mixed reverseTransform(mixed $value)

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.
