Common Problems with Using Dynamic Method Dispatch in Polymorphism
Performance Slowdowns: Dynamic method dispatch can slow things down. This happens because the system has to look up methods in tables. In some programming languages like Java, this can make things up to 30% slower compared to static dispatch methods.
More Complex Code: Using dynamic dispatch can make the code harder to understand. This can make it tough for anyone reading or fixing the code. Studies show that over 70% of developers find it tricky to fix errors in polymorphic code.
Chance of Errors While Running: Some errors show up only when the program is running. For instance, if methods are incorrectly linked, it can lead to more mistakes. This can increase software problems by about 20%, which means testing the code carefully is very important.
Type Safety Problems: Dynamic dispatch can make checking types more complicated. If it’s not handled well, it can lead to a 15% rise in type-related errors.
Missed Optimization Chances: Since compilers can’t optimize dispatched methods well, it can slow down the program. Estimates of performance loss in poorly designed systems can range from 10% to 50%.
