This function can be used to convert an aggregate map a into a "normal" map b (see Special nodes for aggregate maps in source structure). You can then work with the "normal" map as usual. It is also shown in a Mapping test.
The aggregate map a is then deleted.
The return value of the function is the number of entries of the generated map b.
Parameters
Parameter | Description |
|---|---|
a | Name of the aggregate map to be converted. |
b | Name of the "normal" map to be created. |
c | The separator within an entry in map b that is used to separate the values of the different groupings (see Special nodes for aggregate maps in source structure). |
d | (optional) A sorting of the groupings within an entry in map b can be specified here. Example: desc(2) creates a descending sort (ascending with asc) based on the values of the second source structure field. Multiple sortings can also be carried out, e.g. with asc(1),desc(2). NOTE: See also subsection "Sorting" in section Special nodes for aggregate maps in source structure. |
