    public 
function TFPExpressionParser.HasAggregate : Boolean;

    Description

    The HasAggregate method determines whether the current expression contains any aggregate functions such as Sum, Count, Average, Min, or Max. Aggregate functions require special handling during evaluation.

    This information is important for determining the evaluation strategy, as expressions with aggregates may need multiple evaluation passes or special initialization steps.
