There is lot of formatting issue 😬 but this is common issue from contribution where eclipse is not used 😞
(Tthis is probably a topic to address but hard to put it in priority list)

If I didn't missed something for now you only target TEXT and TLV correct ? any reason to not support other content format ?

You should also add coreLink support to LwM2mTestObject class
So you can easily test it with leshan-client-demo and leshan-server-demo.

@jvermillard I push some more code. You can review it if you want.

With my last commit, you should be able to test coreLink with leshan-client-demo, try to play with object 3442 and Randomize, Reset, Clear, CoreLnk Value and Multiple CoreLink value resources.

About tests, we should add integration tests, at least in WriteSingleValueTest, this will create a test for all content format.
(I don't know if keep the unit test LwM2mNodeDecoderTest 🤔)

We should also add support of write coreLink in leshan-server-demo.

And also support for other content format.

(I found a kind of bug with link serialization with rootpath but as this is not related to this PR, I try to fix this in another commit or PR)

[sbernard31]

I finally added :

• write support
• WriteSingleValueTest
• and support for other decoder/encoder
