/**
* TParameterMap corresponds to the <parameterMap> element.
*
* TParameterMap holds one or more parameter child elements that map object
* properties to placeholders in a SQL statement.
*
* A TParameterMap defines an ordered list of values that match up with the
* placeholders of a parameterized query statement. While the attributes
* specified by the map still need to be in the correct order, each parameter
* is named. You can populate the underlying class in any order, and the
* TParameterMap ensures each value is passed in the correct order.
*
* Parameter Maps can be provided as an external element and inline.
* The <parameterMap> element accepts two attributes: id (required) and extends (optional).
