The next commit needs to access compat policy from the generic visitor core. Move it there from qobject input and output visitor. Signed-off-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> Message-Id: <20211025042405.3762351-4-armbru@redhat.com>

|
|
* Create a QObject output visitor for @obj
|
|
*
|
|
* A QObject output visitor visit builds a QObject from QAPI Object.
|
|
* This simultaneously walks the QAPI object and the QObject being
|
|
* built. The latter walk starts at @obj.
|
|
*
|
|
* visit_type_FOO() creates a QObject for QAPI type FOO. It creates a
|
|
* QDict for struct/union types, a QList for list types, QString for
|
|
* type 'str' and enumeration types, QNum for integer and float
|
|
* types, QBool for type 'bool'. For type 'any', it increments the
|
|
* QObject's reference count. For QAPI alternate types, it creates
|
|
* the QObject for the member that is in use.
|
|
*
|
|
* visit_start_struct() ... visit_end_struct() visits a QAPI
|
|
* struct/union and creates a QDict. Visits in between visit the
|
|
* members. visit_optional() is true when the struct/union has this
|
|
* member. visit_check_struct() does nothing.
|
|
*
|
|
* visit_start_list() ... visit_end_list() visits a QAPI list and
|
|
* creates a QList. Visits in between visit list members, one after
|
|
* the other. visit_next_list() returns NULL when all QAPI list
|
|
* members have been visited. visit_check_list() does nothing.
|
|
*
|
|
* visit_start_alternate() ... visit_end_alternate() visits a QAPI
|
|
* alternate. The visit in between creates the QObject for the
|
|
* alternate member that is in use.
|
|
*
|
|
* Errors are not expected to happen.
|
|
*
|
|
* The caller is responsible for freeing the visitor with
|
|
* visit_free().
