Where to find complete reference for LO-UNO Class?

[Paijo]

I want to write a macro, but lack of reference about UNO class and object.
Where I can find complete reference about uno class and object used in LibreOffice?

I try write macro for calc with relative range address, but can’t find any related reference.

Explanation of some recorded macros are found in Old OpenOfice macro pages. Thank you for the link.
