DataTransformerChain
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.
Parameters
| mixed | $value | The value in the transformed representation |
Return Value
| mixed | The value in the original representation |
Exceptions
| TransformationFailedException |
DataTransformerInterface[] getTransformers()
Return Value
| DataTransformerInterface[] |
