This rule validates that:

  • ApexDoc comments are present for classes, methods, and properties that are public or global, excluding overrides and test classes (as well as the contents of test classes).
  • ApexDoc comments are present for classes, methods, and properties that are protected or private, depending on the properties reportPrivate and reportProtected.
  • ApexDoc comments should contain @description depending on the property reportMissingDescription.
  • ApexDoc comments on non-void, non-constructor methods should contain @return.
  • ApexDoc comments on void or constructor methods should not contain @return.
  • ApexDoc comments on methods with parameters should contain @param for each parameter, in the same order as the method signature.
  • ApexDoc comments are present on properties is only validated, if the property reportProperty is enabled. By setting reportProperty to false, you can ignore missing comments on properties.

Method overrides and tests are both exempted from having ApexDoc.
