DEPENDENCY_TYPE in OBJECT_DEPENDENCIES explanation

Hello everyone.

I would like to get more information about the meaning of "magic" numbers as values of DEPENDENCY_TYPE column of OBJECT_DEPENDENCIES view.

All I found it this page:

https://help.sap.com/hana_one/html/_o_b_j_e_c_t__d_e_p_e_n_d_e_n_c_i_e_s.html

but it contains no good explanation on the column.

For example, is it right that "1" means "direct dependency"?
