Class JSONConverter

java.lang.Object

org.cryptimeleon.math.serialization.converter.Converter<java.lang.String>

org.cryptimeleon.math.serialization.converter.JSONConverter

Direct Known Subclasses:

JSONPrettyConverter

public class JSONConverter
extends Converter<java.lang.String>

Allows converting between a Representation object and a JSON structure.

The output is not optimized for legibility, i.e. no whitespaces. For creating pretty-printed JSON output, see JSONPrettyConverter.

Note that the order of attributes in a JSON Object is meaningless. However, this Converter guarantees a consistent order between calls, making the Representation -> String relation left-unique (i.e. a well-defined mapping). This allows this Converter to be used for, e.g,. HashRepresentationIntoStructure, and similar tasks that require a unique and consistent output.
