[Geotools-devel] [FE] in need of an implementation hint

[John B. <che...@fr...>]

Hi,

I have to query a search engine from a Filter Encoding (FE).. So I need to
convert the expression to a String.

I'm using the parsing method of geotools like so:

    Configuration configuration = new
org.geotools.filter.v1_1.OGCConfiguration();
    Parser parser = new Parser( configuration );
    try{
        //the xml filter instance document
        InputStream myXmlFilter = new FileInputStream(uriToMyXmlFilterFile);
        //parse
        filter = (Filter) parser.parse( myXmlFilter );
    }

And I'm getting a String interpretation simply using:
   
    filter.toString()


My problem is that the String interpretation returned is too complex for my
search engine, on many points.
The parse method, much further into sub-instanciations, is calling some
toString to concatenate the final String.
In fact, I would like to modify the toString() method of the
GeometryFilterImpl class (mainly).

My real question there, unless some have a complete different issue to my
problem, is how to re-write, extends or whatever enough from geotools to be
able to custom that part..?

Hope have been clear
John
