API Changes

Deprecated API

Deprecated APIs

Internal API

Those APIs are not intended to be used by clients, and will be hidden or removed with PMD 7.0.0. You can identify them with the @InternalApi annotation. You’ll also get a deprecation warning.

JavaLanguageHandler
JavaLanguageParser
JavaDataFlowHandler
Implementations of RuleViolationFactory in each language module, eg JavaRuleViolationFactory. See javadoc of RuleViolationFactory.
Implementations of RuleViolation in each language module, eg JavaRuleViolation. See javadoc of RuleViolation.
RuleFactory
RuleBuilder
Constructors of RuleSetFactory, use factory methods from RulesetsFactoryUtils instead
getRulesetFactory
AbstractApexNode
AbstractApexNodeBase, and the related visit methods on ApexParserVisitor and its implementations. Use ApexNode instead, now considers comments too.

For removal

pmd-core
- DFAGraphRule and its implementations
- DFAGraphMethod
- Many methods on the Node interface and AbstractNode base class. See their javadoc for details.
- Node#isFindBoundary is deprecated for XPath queries.
- Many APIs of net.sourceforge.pmd.lang.metrics, though most of them were internal and probably not used directly outside of PMD. Use MetricsUtil as a replacement for the language-specific façades too.
- QualifiableNode, QualifiedName
pmd-java
- AbstractJavaParser
- AbstractJavaHandler
- ASTAnyTypeDeclaration.TypeKind
- ASTAnyTypeDeclaration#getKind
- JavaQualifiedName
- ASTCatchStatement#getBlock
- ASTCompilationUnit#declarationsAreInDefaultPackage
- JavaQualifiableNode
- net.sourceforge.pmd.lang.java.qname and its contents
- MethodLikeNode
  - Its methods will also be removed from its implementations, ASTMethodOrConstructorDeclaration, ASTLambdaExpression.
- ASTAnyTypeDeclaration#getImage will be removed. Please use getSimpleName() instead. This affects ASTAnnotationTypeDeclaration#getImage, ASTClassOrInterfaceDeclaration#getImage, and ASTEnumDeclaration#getImage.
- Several methods of ASTTryStatement, replacements with other names have been added. This includes the XPath attribute @Finally, replace it with a test for child::FinallyStatement.
- Several methods named getGuardExpressionNode are replaced with getCondition. This affects the following nodes: WhileStatement, DoStatement, ForStatement, IfStatement, AssertStatement, ConditionalExpression.
- ASTYieldStatement will not implement TypeNode anymore come 7.0.0. Test the type of the expression nested within it.
- JavaMetrics, JavaMetricsComputer
pmd-apex
