Check if expression is an aggregate
Source position: fpexprpars.pp line 650
public class function TAggregateExpr.IsAggregate: Boolean; override; |
Returns true for aggregate expressions
The TAggregateExpr.IsAggregate class function returns True to indicate that this expression is an aggregate expression. It overrides the default behavior from TFPExprNode which returns False for regular expressions.
The method is used by the expression parser to identify aggregate expressions and handle them differently from regular expressions, as aggregates require special processing including initialization and incremental updates.
