CanonicalJsonFormatter (Vitam API Reference (2.15.1-1))

```
public final class CanonicalJsonFormatter
extends Object
```
Json serializer with canonicalization. Ensures deterministic encoding for consistent hashing purposes. Serializes a json node object in a canonical deterministic encoding. This encoding must never be changed to avoid inconsistent hashing of previously encoded data. String literals are encoded as follows in the format '"char1char2..."' - Simple escaping is applied for and only for the following characters : '"', '\\', '\b', '\f', \n', '\r' & '\t'. - Printable ascii chars are not escaped [32 - 127] - 4 digit hex escaping for any other character (ሴ). Integer literals are encoded as is (0, 1234, -1234) Floating numbers are formatted using Double.format() Arrays are encoded is the '[entry1,entry2...]' format. Objects entries are encoded with sorted keys in the '{"key1":value1,...)}' No pretty-printing is appended (no line breaks or spacing is appended).
