Class MethodDeclarationLengthCheck

java.lang.Object
com.puppycrawl.tools.checkstyle.AbstractAutomaticBean
com.puppycrawl.tools.checkstyle.api.AbstractViolationReporter
com.puppycrawl.tools.checkstyle.api.AbstractCheck
com.qulice.checkstyle.MethodDeclarationLengthCheck
All Implemented Interfaces:
com.puppycrawl.tools.checkstyle.api.Configurable, com.puppycrawl.tools.checkstyle.api.Contextualizable

public final class MethodDeclarationLengthCheck extends com.puppycrawl.tools.checkstyle.api.AbstractCheck
Checks that method and constructor declarations do not span multiple lines when the entire signature can fit on one line within the limit.

This is how a correct declaration looks like:

 public Foo(final int max) throws IOException {
     ...
 }
 

And this is what will be reported:

 public Foo(final int max)
     throws IOException {
     ...
 }
 

The reason is explained in this article: one should put as much as possible on one line within the configured limit (80 by default). See #647.
