Is there a way to include, at the document level, the ability to raise an exception when specific conditions occur?

Example

<<if [cliente.numeroAbitanti > 1000 ]>>
    <<throw "Number xxxx is too high">>
<<endif>>

There is no special tag to achieve this. However, this can be easily done using a static method of a custom type defined in your code like this:

public class Util
{
    // The method must have a return type.
    public static Object throwException(String message)
    {
        throw new RuntimeException(message);
    }
}

LINQ Reporting Engine should be made aware of the class before using it in a template as follows:

ReportingEngine engine = new ReportingEngine();
engine.getKnownTypes().add(Util.class);
engine.buildReport(...);

Then, the method can be used to throw an exception upon a condition defined in a template like so:

<<if [cliente.numeroAbitanti > 1000]>>
    <<[Util.throwException("Number xxxx is too high")]>>
<</if>>
