Auto-registry full text functions.

[FRANCISCO XAVIER SUMBA TORAL]

Hi,

The FunctionRegistry class no longer manage continuos synchronised checking in 
RDF4J and Sesame 4, instead they use a helper [1]. So, what is the purpose to 
auto-register the full text functions [2 & 3] at instantiation time? Besides, 
once the functions implement the Function class and are registered in the 
services file, the FunctionRegistry keeps track of them automatically. So, why 
this is necessary on those function?

FulltextQueryFunction:
    static {
        if(!FunctionRegistry.getInstance().has(“full text query uri")) {
            FunctionRegistry.getInstance().add(new FulltextQueryFunction());
        }
    }

FulltextSearchFunction:
    static {
        if(!FunctionRegistry.getInstance().has(“full text search uri")) {
            FunctionRegistry.getInstance().add(new FulltextSearchFunction());
        }
    } 

It could be deleted, or is there something that I’m missing?

Cheers,
Xavier.
