Class ChainingConstructorIgnoresParameter

java.lang.Object

com.google.errorprone.bugpatterns.BugChecker

com.google.errorprone.bugpatterns.ChainingConstructorIgnoresParameter

All Implemented Interfaces:

BugChecker.CompilationUnitTreeMatcher, BugChecker.MethodInvocationTreeMatcher, BugChecker.MethodTreeMatcher, Suppressible, Serializable

public final class ChainingConstructorIgnoresParameter
extends BugChecker
implements BugChecker.CompilationUnitTreeMatcher, BugChecker.MethodInvocationTreeMatcher, BugChecker.MethodTreeMatcher

Checks, if two constructors in a class both accept Foo foo and one calls the other, that the caller passes foo as a parameter. The goal is to catch copy-paste errors:

   MissileLauncher(Location target, boolean askForConfirmation) {
     ...
   }
   MissileLauncher(Location target) {
     this(target, false);
   }
   MissileLauncher(boolean askForConfirmation) {
     this(TEST_TARGET, false); // should be askForConfirmation
   }
