Annotation Type TransactionalAdvice

@Target(value={ANNOTATION_TYPE,METHOD,TYPE})
 @Retention(value=RUNTIME)
 @Around
 @Type(value=TransactionalInterceptor.class)
 @Internal
public @interface TransactionalAdvice

Meta annotation that other transactional annotations like Spring's and javax.transaction.Transactional map to such as to enable transactional advice. Shouldn't be used directly.

This annotation is declared with a target of ElementType.ANNOTATION_TYPE so that is used only as a meta-annotation. In actual code you would use javax.transaction.Transaction

readOnly

public abstract boolean readOnly

true if the transaction is read-only.

false
