Get an Exception

Similar to all other items, an exception can be read from the application log using methods GET_ITEM and GET_ALL_ITEMS of interface IF_BALI_LOG. The exception object, which is returned by these methods, uses interface IF_BALI_EXCEPTION_GETTER.

The interface supports all attributes and methods of interface IF_BALI_ITEM_GETTER.

Interface IF_BALI_EXCEPTION_GETTER contains the following additional attributes:

• EXCEPTION_CLASS: The name of the exception class.

• EXCEPTION_ID_NAME: Name of the text ID of the ABAP exception.

Example:

Load a single log from the database which uses log handle l_handle and output some attributes of the first item, if it is an exception:

Sample Code:

...
 DATA l_handle TYPE if_bali_log=>ty_handle.

 TRY.
     DATA(l_log) = cl_bali_log_db=>get_instance( )->load_log( handle = l_handle ).
     DATA(l_item) = l_log->get_item( log_item_number = '1' ).

     IF l_item->category = if_bali_constants=>c_category_exception.
       DATA(l_exception_ref) = CAST if_bali_exception_getter( l_item ).
       out->write( |{ l_exception_ref->exception_class } { l_exception_ref->exception_id_name }| ).
     ENDIF.
   CATCH cx_bali_runtime INTO DATA(l_exception).
     out->write( l_exception->get_text(  ) ).
 ENDTRY.
