If you look at the examples that come with the library (hd44780_I2Cexp class) you will see that the functions (commands) are the same as the LiquidCrystal libraries.

From the hd44780 library Wiki:

A major design and functional goal is to not only make the library API compatible with the IDE bundled LiquidCrystal library across all h/w interfaces,

The main github page for the hd44780 library lists the functions and the extensions with descriptions of what they do.

See also the LiquidCrystal library reference page.
