----------------------------------
I comment with Gabriel and Andrea the most natural ";" delimiter, and we agree
to do the change now.
> Allow CQL Parser to parse a list of filters separated by a delimiter character
> ------------------------------------------------------------------------------
>
> Key: GEOT-1162
> URL: http://jira.codehaus.org/browse/GEOT-1162
> Project: GeoTools
> Issue Type: New Feature
> Components: new modules
> Affects Versions: 2.3.1, 2.4.M0
> Reporter: Gabriel Roldán
> Assignee: Mauricio Pazos
> Fix For: 2.3.1, 2.4.M0
>
>
> GeoServer needs to parse a list of filters from a CQL_FILTER kvp parameter in
> order to apply each one to a layer in the order of appearance in the LAYERS
> kvp parameter.
> For exaple:
> {{attr1 > 5|attr2 between 1 and 7| attr3 = 'text|with|delimiter'}} should be
> parsed to a {{List}} with the three different Fitlers. It would be far easier
> to instruct the javacc parser to do that than doing it at the GeoServer side
> 'by hand'.
> ---------
> The requirement from Andrea:
> the WSF filter spec uses ( and ) to separate OGC filters in a get
> request. I'm looking for a separator for CQL. It seems [ and ] would do?
> What I need to do is to parse something like:
> {{CQL_FILTER=[A + B < 10][ATT1 = "Gimbo"]}}
> or
> {{CQL_FILTER=A + B < 10|ATT1 = "Gimbo"}}
> into two separate filters. Does CQL have the concept of a filter list?
> I need to pick up a character that has low likeliness of interfering
> with the CQL itself, since our way to split OGC filters is to use
> a lame StringTokenizer, that can't really manage nesting
