Zenoh serializer.

This class is a utility for serializing elements of type T into ZBytes.

This class supports the following types:

• Boolean

• Byte

• Short

• Int

• Long

• Float

• Double

• List

• String

• ByteArray

• Map

For List and Map, the inner types can be a combination of the above types, including themselves.

Due to Java's type erasure, an actual implementation of this abstract class needs to be created (see the examples below).

This serialization utility can be used across the Zenoh ecosystem with Zenoh versions based on other supported languages such as Rust, Python, C and C++. This works when the types are equivalent (a Byte corresponds to an i8 in Rust, a Short to an i16, etc).

Example for a basic type, in this case an integer:

Integer input = 123456;
ZSerializer<Integer> serializer = new ZSerializer<>() {};
ZBytes zbytes = serializer.serialize(input);

ZDeserializer<Integer> deserializer = new ZDeserializer<>() {};
Integer output = deserializer.deserialize(zbytes);
assert input.equals(output);

Examples for parameterized types:

• List

List<Integer> input = List.of(1, 2, 3, 4, 5);
ZSerializer<List<Integer>> serializer = new ZSerializer<>() {};
ZBytes zbytes = serializer.serialize(input12);

ZDeserializer<List<Integer>> deserializer = new ZDeserializer<>() {};
List<Integer> output = deserializer.deserialize(zbytes);
assert input.equals(output);

• Map

Map<String, Integer> input = Map.of("one", 1, "two", 2, "three", 3);
ZSerializer<Map<String, Integer>> serializer = new ZSerializer<>() {};
ZBytes zbytes = serializer.serialize(input);

ZDeserializer<Map<String, Integer>> deserializer = new ZDeserializer<>() {};
Map<String, Integer> output = deserializer.deserialize(zbytes);
assert input.equals(output);

As mentioned, for List and Map, the inner types can be a combination of the above types, including themselves. Here's an example with a List of Maps:

List<Map<String, Integer>> input = List.of(Map.of("a", 1, "b", 2));
ZSerializer<List<Map<String, Integer>>> serializer = new ZSerializer<>() {};
ZBytes zbytes = serializer.serialize(input);

ZDeserializer<List<Map<String, Integer>>> deserializer = new ZDeserializer<>() {};
List<Map<String, Integer>> output = deserializer.deserialize(zbytes);
assert input.equals(output);
