TFPExpressionParser.Expression property

Declaration

property Expression: Ansistring read FExpression write SetExpression;

Description

The Expression property contains the expression text that will be parsed and evaluated by the parser. Setting this property triggers the parsing process, converting the text into an internal expression tree representation.

The expression string follows the syntax rules supported by the parser, including operators, functions, variables, and constants. Any syntax errors in the expression will be reported during the parsing phase.
