From Lazarus wiki
- properties should not start with a verb, but with a noun
- methods should start with a verb
- method names "GetFoo" are reserved for property "Foo" getters
- method names "SetFoo" are reserved for property "Foo" setters
- method names "DoFoo" are reserved for calling event "OnFoo"
- suggestion: use "UpdateFoo" instead of "DoSetFoo" to update certain characteristics or to make some assertion valid
