+/**
+ * TResultMap corresponds to <resultMap> mapping tag.
+ *
+ * A TResultMap lets you control how data is extracted from the result of a
+ * query, and how the columns are mapped to object properties. A TResultMap
+ * can describe the column type, a null value replacement, and complex property
+ * mappings including Collections.
+ *
+ * The <resultMap> can contain any number of property mappings that map object
+ * properties to the columns of a result element. The property mappings are
+ * applied, and the columns are read, in the order that they are defined.
+ * Maintaining the element order ensures consistent results between different
+ * drivers and providers.
+ *
+ * The {@link Class setClass()} property must be a PHP class object or array instance.
+ *
+ * The optional {@link Extends setExtends()} attribute can be set to the ID of
+ * another <resultMap> upon which to base this <resultMap>. All properties of the
+ * "parent" <resultMap> will be included as part of this <resultMap>, and values
+ * from the "parent" <resultMap> are set before any values specified by this <resultMap>.
