If you have access to the object itself, e.g., Serial, you can say Serial.println(). If your library only has a pointer to the object, you have use ->, the dereference operator: serialPtr->println(). The result is the same: calling the object's 'println()' member. The difference is in how the compiled code gets you to that member.
