Interface ContentTransformer<InternalType>

All Known Subinterfaces:

ImageContentTransformer, RawContentTransformer, TextContentTransformer

public interface ContentTransformer<InternalType>

This interface defines the API that has to be implemented by classes that are capable of transforming content data after it's initially loaded.

The content attributes are provided to the transform method and can be used to provide hints for the transformation.

Each transformer is supposed to transform content data of a certain data type and return the transformed content in the same data type. You should be careful that this data type corresponds to the data type that's returned by the format method of the formatter that handles the content's mime type.
