If you fear that the appearance of many Groovy Library function calls may make your code unreadable, consider creating an alias function. An alias allows you to call a local function that reroutes to a library, giving you more flexibility with how your code looks.
...
To improve readability, always assign the library element instances to a variable before using them:
| Code Block | ||
|---|---|---|
| ||
final roundingUtils = libs.MathLuib.RoundingUtils
final someNumber = ...
roundingUtils.round(someNumber, 2) |
This practice dramatically improves the readability of your code as it grows in size.
| Tip |
|---|
Do this: |
| Code Block |
|---|
final productUtils = libs.ProductLib.ProductUtils
final pricinUtils = libs.PricingLib.PricingUtils
final product = productUtils.getProduct(...)
final cost = productUtils.getCost(...)
final margin = pricingUtils.getMargin(...)
final listPrice = pricingUtils.calculatePrice(product, cost, margin) |
| Warning |
|---|
Don’t do this: |
| Code Block |
|---|
final productUtils = libs.ProductLib.ProductUtils.getProduct(...)
final costUtils = libs.ProductLib.ProductUtils.getCost(...)
final marginUtils = libs.PricingLib.PricingUtils.getMargin(...)
final listPrice = libs.PricingLib.PricingUtils.calculatePrice(product, cost, margin) |
