I don’t know if the title is appropriate but this is a design question.
I am designing a Java class which has a method which does heavy calculation and I am wondering there is a clean way to avoid this calculation every time the method is called. I know that the calling code can handle this but should it always be the responsibility of the calling code?.

To elaborate – I was writing a class for thousand dimensional vectors with a method to calculate the magnitude.So every time this method will be called it will calculate the magnitude over all the dimensions.
