swift - Calling the built-in function with the same name as a custom function -


i have following code round value nearest number:

func round(_ value: double, tonearest nearest: double) -> double {     let roundedvalue = round(value / nearest) * nearest     return roundedvalue }

however, following complaint because use same name method builtin one:

missing argument parameter 'tonearest' in call

is there way around this? i.e. builtin round(value / nearest)?

thanks.

as shown in following answer:

most darwin/c rounding methods readily available native swift methods, types conforming floatingpoint (e.g. double , float). means if set on implementing own rounding method using same logic in question, can use rounded() method of floatingpoint, make use of .tonearestorawayfromzero rounding rule, (as described in linked answer) equivalent darwin/c round(...) method.

applied modify custom round(_:tonearest:) function:

func round(_ value: double, tonearest nearest: double) -> double {     return (value / nearest).rounded() * nearest }

python - Best design pattern for collection of objects -

i have following architecture: +-----------------+ | collection | | | | | | | | | +-----------------+ | ^ | | create() | | | | v | getitem(b) +------------+ | | item | | | | | | +------+ | | +------------+ a class managing collection of items, creates items. , these items may need other items collection. the actual code in python, , collection passes parameter created item . see it, bad practice. improvement can see pass few functions of collection needed item , instead of whole instance. for example: class collection: getitem(self, id): ... createitem(self, id): item = item(id, self) # <-- pass self ... class item: __init__(self, id, col): ... col.getite...
