Description
TFPConvertNode is the base class for all type conversion operations in the expression parser.
It provides the fundamental infrastructure for converting values between different data types during expression evaluation.
The class extends TFPExprNode to provide conversion-specific functionality that enables automatic type coercion and explicit type casting operations within expressions.
Derived classes implement specific conversion logic for different source and target type combinations, ensuring type safety and proper value transformation 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.
