Inheritance¶
Description¶
The TFPExprVariable class represents a variable reference in an expression tree. Variables are identifiers that hold values and can be referenced by name within expressions to retrieve their current values.
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.
