Declaration
EExprScanner = class(Exception)Inheritance
Description
This exception class is raised by the TFPExpressionScanner when lexical analysis errors occur during expression scanning. It indicates problems encountered while tokenizing the input expression text.
Common scenarios that trigger this exception include:
- Invalid character sequences that cannot be recognized as valid tokens
- Malformed string literals (unclosed quotes)
- Invalid numeric literals (malformed number formats)
- Unexpected characters that violate the expression grammar
The exception typically provides detailed error information including the position where the error occurred and a description of what went wrong during the scanning process.
