31 | /** |
---|
32 | * <p> |
---|
33 | * corrects older JFC log files which sometimes do not contain correct source specifications for |
---|
34 | * events. It parses the file and adds component specifications to the sources, that do not have |
---|
35 | * them. For each invalid source it checks, if there is another source with the same |
---|
36 | * <code>toString</code> parameter but a complete list of components. If one is found, it is reused |
---|
37 | * as source for the event with the wrong source. If none is found, a new component list is |
---|
38 | * generated. This contains as parent components the components of the source of the previous event. |
---|
39 | * The leaf component is parsed from the <code>toString</code> parameter that is provided with the |
---|
40 | * source specifications. The resulting leaf nodes are not fully correct. They may pretend to |
---|
41 | * be equal although they are not. Furthermore they may resist at a position in the GUI tree where |
---|
42 | * they are not in reality. But more correctness is not achievable based on the |
---|
43 | * <code>toString</code> parameter. |
