17# @ObjectPropertyInfo:
18#
19# @name: the name of the property
20#
21# @type: the type of the property.  This will typically come in one of four
22#        forms:
23#
24#        1) A primitive type such as 'u8', 'u16', 'bool', 'str', or 'double'.
25#           These types are mapped to the appropriate JSON type.
26#
27#        2) A child type in the form 'child<subtype>' where subtype is a qdev
28#           device type name.  Child properties create the composition tree.
29#
30#        3) A link type in the form 'link<subtype>' where subtype is a qdev
31#           device type name.  Link properties form the device model graph.
32#
33# @description: if specified, the description of the property.
34#
35# @default-value: the default value, if any (since 5.0)
36#
37# Since: 1.2

46# @qom-list:
47#
48# This command will list any properties of a object given a path in the object

50#
51# @path: the path within the object model.  See @qom-get for a description of
52#        this parameter.
53#

75# @qom-get:
76#
77# This command will get a property from a object model path and return the
78# value.
79#
80# @path: The path within the object model.  There are two forms of supported
81#        paths--absolute and partial paths.
82#
83#        Absolute paths are derived from the root object and can follow child<>
84#        or link<> properties.  Since they can follow link<> properties, they
85#        can be arbitrarily long.  Absolute paths look like absolute filenames
86#        and are prefixed  with a leading slash.
87#
88#        Partial paths look like relative filenames.  They do not begin
89#        with a prefix.  The matching rules for partial paths are subtle but
90#        designed to make specifying objects easy.  At each level of the
91#        composition tree, the partial path is matched as an absolute path.
92#        The first match is not returned.  At least two matches are searched
93#        for.  A successful result is only returned if only one match is
94#        found.  If more than one match is found, a flag is return to
95#        indicate that the match was ambiguous.
96#
97# @property: The property name to read
98#
99# Returns: The property value.  The type depends on the property
100#          type. child<> and link<> properties are returned as #str
101#          pathnames.  All integer property types (u8, u16, etc) are
102#          returned as #int.
103#
104# Since: 1.2
