/**
* A {@link Processor} implementation for converting rows extracted from any implementation of {@link AbstractParser} into java objects.
*
* The class types passed to the constructor of this class must contain the annotations provided in {@link com.univocity.parsers.annotations}.
*
*
For each row processed, one or more java bean instances of any given class will be created with their fields populated.
*
Each individual instance will then be sent to the {@link AbstractMultiBeanProcessor#beanProcessed(Class, Object, Context)} method, where the user can access the
* beans parsed for each row.
