ValidatorException

ValidatorException is a type of exception often encountered in software development, particularly in systems that involve data validation. It is thrown when a specific validation rule fails, indicating that the data being processed does not meet the required criteria. This exception serves as a signal to the calling code that an invalid state has been detected.

The purpose of a ValidatorException is to provide a clear and structured way to report validation errors. Instead of allowing the program to continue with potentially incorrect data, which could lead to unpredictable behavior or further errors, the exception interrupts the normal flow and signals that an issue needs to be addressed. This allows developers to catch the exception and handle the validation failure appropriately, such as by logging the error, returning an error message to the user, or rolling back a transaction.

ValidatorException typically carries information about the specific validation rule that was violated and potentially the data that caused the failure. This context is crucial for debugging and resolving the underlying data integrity problems. By encapsulating validation failures in a dedicated exception type, software systems can maintain robustness and ensure data quality. The implementation and specific properties of ValidatorException can vary across different programming languages and frameworks, but its core function remains consistent: to indicate a failure in data validation.
