eu.solven.cleanthat.engine.java.refactorer.mutators.AUseXIsEmpty

All Implemented Interfaces:

ICountMutatorIssues, IJavaparserAstMutator, IJavaparserNodeMutator, IMutator, IMutatorExternalReferences, IWalkingMutator<com.github.javaparser.ast.Node,com.github.javaparser.ast.Node>

Direct Known Subclasses:

UseCollectionIsEmpty, UseStringIsEmpty

public abstract class AUseXIsEmpty
extends AJavaparserExprMutator

Migrate from 'm.size() == 0’ to ’m.isEmpty()'. Works with Collection, Map and String.
