Annotation Type Advice.Thrown


  • @Documented
    @Retention(RUNTIME)
    @Target(PARAMETER)
    public static @interface Advice.Thrown

    Indicates that the annotated parameter should be mapped to the Throwable thrown by the instrumented method or to null if the method returned regularly. Note that the Java runtime does not enforce checked exceptions. In order to capture any error, the parameter type must therefore be of type Throwable. By assigning another value or null to this parameter, a thrown exception can be suppressed.

    Note: This annotation must only be used on exit advice methods.

      • readOnly

        boolean readOnly

        Indicates if it is possible to write to this parameter. If this property is set to false, the annotated type must be equal to the type declaring the instrumented method if the typing is not also set to Assigner.Typing.DYNAMIC. If this property is set to true, the annotated parameter can be any super type of the instrumented method's declaring type.

        Important: This property must be set to true if the advice method is not inlined.

        Returns:
        true if this parameter is read-only.
        Default:
        true
