+/**
+ * @class Query Provides a framework to construct complex queries in a safer environment.
+ *
+ * The usage of this class depends on the type of query you are executing, but the basic idea is to
+ * construct a query out of pluggable classes.
+ *
+ * Once constructed SQL can be generated using the toString method, this should happen automatically
+ * if you pass the Query object to get_data or similar.
+ *
+ * To construct a query, create a new Query() object and begin populating it with the various classes
+ * that define the various aspects of the query.
+ *
+ * Notes:
+ * - You do not have to specify things in any particular order, provided you specify all required
+ * components.
+ * - With database tables you do not have to specify your db prefix, this will be added automatically.
+ * - When constructing your query keep an eye on the error log - any problems will get spit out here.
+ * Note also that __toString won't let you throw Exceptions (!!!) so these are caught and echoed to
+ * the log instead.
+ *
+ * Here is an example of a select query which requests some data out of the entities table with an
+ * order and limit that uses a subset where and some normal where queries:
+ *
+ * <blockquote>
+ * // Construct the query
+ * $query = new Query();
+ *
+ * // Say which table we're interested in
+ * $query->addTable(new TableQueryComponent("entities"));
+ *
+ * // What fields are we interested in
+ * $query->addSelectField(new SelectFieldQueryComponent("entities","*"));
+ *
+ * // Add access control (Default access control uses default fields on entities table.
+ * // Note that it will error without something specified here!
+ * $query->setAccessControl(new AccessControlQueryComponent());
+ *
+ * // Set a limit and offset, may be omitted.
+ * $query->setLimitAndOffset(new LimitOffsetQueryComponent(10,0));
+ *
+ * // Specify the order, may be omitted
+ * $query->setOrder(new OrderQueryComponent("entities", "subtype", "desc"));
+ *
+ * // Construct a where query
+ * //
+ * // This demonstrates a WhereSet which lets you have sub wheres, a
+ * // WhereStatic which lets you compare a table field against a value and a
+ * // Where which lets you compare a table/field with another table/field.
+ * $query->addWhere(
+ * new WhereSetQueryComponent(
+ * array(
+ * new WhereStaticQueryComponent("entities", "subtype","=", 1),
+ * new WhereQueryComponent("entities","subtype","=", "entities", "subtype")
+ * )

- * To construct a query, create a new Query() object and begin populating it with the various classes
- * that define the various aspects of the query.
- *
- * Notes:
- * - You do not have to specify things in any particular order, provided you specify all required
- * components.
- * - With database tables you do not have to specify your db prefix, this will be added automatically.
- * - When constructing your query keep an eye on the error log - any problems will get spit out here.
- * Note also that __toString won't let you throw Exceptions (!!!) so these are caught and echoed to
- * the log instead.
- *
- * Here is an example of a select query which requests some data out of the entities table with an
- * order and limit that uses a subset where and some normal where queries:
- *
- * <blockquote>
- * // Construct the query
- * $query = new Query();
- *
- * // Say which table we're interested in
- * $query->addTable(new TableQueryComponent("entities"));
- *
- * // What fields are we interested in
- * $query->addSelectField(new SelectFieldQueryComponent("entities","*"));
- *
- * // Add access control (Default access control uses default fields on entities table.
- * // Note that it will error without something specified here!
- * $query->setAccessControl(new AccessControlQueryComponent());
- *
- * // Set a limit and offset, may be omitted.
- * $query->setLimitAndOffset(new LimitOffsetQueryComponent(10,0));
- *
- * // Specify the order, may be omitted
- * $query->setOrder(new OrderQueryComponent("entities", "subtype", "desc"));
- *
- * // Construct a where query
- * //
- * // This demonstrates a WhereSet which lets you have sub wheres, a
- * // WhereStatic which lets you compare a table field against a value and a
- * // Where which lets you compare a table/field with another table/field.
- * $query->addWhere(
- * new WhereSetQueryComponent(
- * array(
- * new WhereStaticQueryComponent("entities", "subtype","=", 1),
- * new WhereQueryComponent("entities","subtype","=", "entities", "subtype")
- * )
- * )
- * );
- *
- * get_data($query);
- * </blockquote>
