-/**
- * DataMapper client, a facade to provide access the rest of the DataMapper
- * framework. It provides three core functions:
- *
- * # execute an update query (including insert and delete).
- * # execute a select query for a single object
- * # execute a select query for a list of objects
- *
- * Do not create this class explicitly, use TDomSqlMapBuilder to obtain
- * an instance by parsing through the xml configurations. Example:
- * <code>
- * $builder = new TDomSqlMapBuilder();
- * $mapper = $builder->configure($configFile);
- * </code>
- *
- * Otherwise use convient classes TMapper or TSqlMap to obtain singleton
- * instances.
