Deprecated ConstructorsConstructorDescriptionIf VisitorState is needed, use
VisitorState.createForUtilityPurposes(com.sun.tools.javac.util.Context), otherwise just use utility methods in ASTHelpers that don't need VisitorSate.Use the equivalent factory methodVisitorState.createForCustomFindingCollection(com.sun.tools.javac.util.Context, com.google.errorprone.DescriptionListener).
