ApexDoc

Since: PMD 6.8.0

Priority: Medium (3)

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.

This rule is defined by the following Java class: net.sourceforge.pmd.lang.apex.rule.documentation.ApexDocRule

Example(s):

/**
 * @description Hello World
 */
public class HelloWorld {
    /**
     * @description Bar
     * @return Bar
     */
    public Object bar() { return null; }
}

This rule has the following properties:

Name Default Value Description Multivalued
reportPrivate false Report private classes, methods and properties no
reportProtected false Report protected classes, methods and properties no
reportMissingDescription true Report missing @description no
reportProperty true Report properties without comments no

Use this rule with the default properties by just referencing it:

<rule ref="category/apex/documentation.xml/ApexDoc" />

Use this rule and customize it:

<rule ref="category/apex/documentation.xml/ApexDoc">
    <properties>
        <property name="reportPrivate" value="false" />
        <property name="reportProtected" value="false" />
        <property name="reportMissingDescription" value="true" />
        <property name="reportProperty" value="true" />
    </properties>
</rule>
