TFPExprIdentifierNode class
Internally used class for identifier nodes in expression trees
Declaration
TFPExprIdentifierNode = class(TFPExprNode)Inheritance
- TFPExprIdentifierNode
- TFPExprNode
- TObject
Descends from it: TFPExprFunction TFPExprVariable
Description
The TFPExprIdentifierNode class represents an identifier reference in the expression tree.
It holds a reference to the identifier definition and handles the resolution and evaluation of variables
and function calls during expression evaluation.
This class is used internally by the TFPExpressionParser class to construct an AST (Abstract Syntax Tree). There is normally no need for you to use or instantiate this class directly.
