RdfException class

Base exception class for all RDF-related errors.

This serves as the root of the exception hierarchy for the RDF library, providing common functionality for all specific exceptions. It captures essential error information including error messages, causes, and source locations.

Specific exception types in the library extend this base class to provide more targeted error handling for different RDF operations (decoding, encoding, validation, etc.).

Example:

try {
  // RDF operation that might fail
} catch (e) {
  if (e is RdfException) {
    // Handle RDF-specific error with access to detailed information
    print(e.message);
    print(e.source);
  } else {
    // Handle other types of errors
  }
}
