public final class MethodCountCheck extends AbstractCheck
Checks the number of methods declared in each type declaration by access modifier or total count.
This check can be configured to flag classes that define too many methods
to prevent the class from getting too complex. Counting can be customized
to prevent too many total methods in a type definition (maxTotal
),
or to prevent too many methods of a specific access modifier (private
,
package
, protected
or public
). Each count is completely
separated to customize how many methods of each you want to allow. For example,
specifying a maxTotal
of 10, still means you can prevent more than 0
maxPackage
methods. A violation won't appear for 8 public methods,
but one will appear if there is also 3 private methods or any package-private methods.
Methods defined in anonymous classes are not counted towards any totals. Counts only go towards the main type declaration parent, and are kept separate from it's children's inner types.
public class ExampleClass { public enum Colors { RED, GREEN, YELLOW; public String getRGB() { ... } // NOT counted towards ExampleClass } public void example() { // counted towards ExampleClass Runnable r = (new Runnable() { public void run() { ... } // NOT counted towards ExampleClass, won't produce any violations }); } public static class InnerExampleClass { protected void example2() { ... } // NOT counted towards ExampleClass, // but counted towards InnerExampleClass } }

tokens
- tokens to check
Type is int[]
.
Default value is:
CLASS_DEF,

To configure the check with defaults:
<module name="MethodCount"/>
To configure the check to allow no more than 30 methods per type declaration:
<module name="MethodCount"> <property name="maxTotal" value="30"/> </module>
To configure the check to allow no more than 10 public methods per type declaration, and 40 methods in total:
<module name="MethodCount"> <property name="maxPublic" value="10"/> <property name="maxTotal" value="40"/> </module>
