java.lang.Object

java.lang.Throwable

java.lang.Exception

java.lang.RuntimeException

com.opencsv.exceptions.CsvRuntimeException

com.opencsv.exceptions.CsvBeanIntrospectionException

All Implemented Interfaces:

Serializable

public class CsvBeanIntrospectionException
extends CsvRuntimeException

This exception is to be thrown when anything goes bad during introspection of beans given to opencsv. It encapsulates exceptions such as NoSuchMethodException, IllegalAccessException and InvocationTargetException. Some might notice that this effectively converts checked exceptions into unchecked exceptions. Introspection exceptions are coding errors that should be fixed during development, and should not have to be handled in production code.

3.9
