com.google.errorprone.bugpatterns.collectionincompatibletype.CollectionIncompatibleType

All Implemented Interfaces:

BugChecker.MemberReferenceTreeMatcher, BugChecker.MethodInvocationTreeMatcher, Suppressible, Serializable

public class CollectionIncompatibleType
extends BugChecker
implements BugChecker.MethodInvocationTreeMatcher, BugChecker.MemberReferenceTreeMatcher

Checker for calling Object-accepting methods with types that don't match the type arguments of their container types. Currently this checker detects problems with the following methods on all their subtypes and subinterfaces:

• Collection.contains(java.lang.Object)
• Collection.remove(java.lang.Object)
• List.indexOf(java.lang.Object)
• List.lastIndexOf(java.lang.Object)
• Map.get(java.lang.Object)
• Map.containsKey(java.lang.Object)
• Map.remove(java.lang.Object)
• Map.containsValue(java.lang.Object)
