/**
 * TParameterProperty corresponds to the <property> tag and defines
 * one object property for the <parameterMap>
 *
 * The {@link NullValue setNullValue()} attribute can be set to any valid
 * value (based on property type). The {@link NullValue setNullValue()} attribute
 * is used to specify an inbound null value replacement. What this means is
 * that when the value is detected in the object property, a NULL will be written
 * to the database (the opposite behavior of an inbound null value replacement).
 * This allows you to use a magic null number in your application for types that
 * do not support null values (such as int, double, float). When these types of
 * properties contain a matching null value (for example, say, -9999), a NULL
 * will be written to the database instead of the value.
