##
# @ObjectPropertyInfo:
#
# @name: the name of the property
#
# @type: the type of the property.  This will typically come in one of four
#        forms:
#
#        1) A primitive type such as 'u8', 'u16', 'bool', 'str', or 'double'.
#           These types are mapped to the appropriate JSON type.
#
#        2) A child type in the form 'child<subtype>' where subtype is a qdev
#           device type name.  Child properties create the composition tree.
#
#        3) A link type in the form 'link<subtype>' where subtype is a qdev
#           device type name.  Link properties form the device model graph.
#
# @description: if specified, the description of the property.
#
# @default-value: the default value, if any (since 5.0)
#
# Since: 1.2

# @qom-list:
#
# This command will list any properties of a object given a path in the object
# model.
#
# @path: the path within the object model.  See @qom-get for a description of
#        this parameter.
#
# Returns: a list of @ObjectPropertyInfo that describe the properties of the
#          object.

##
# @qom-get:
#
# This command will get a property from a object model path and return the
# value.
#
# @path: The path within the object model.  There are two forms of supported
#        paths--absolute and partial paths.
#
#        Absolute paths are derived from the root object and can follow child<>
#        or link<> properties.  Since they can follow link<> properties, they
#        can be arbitrarily long.  Absolute paths look like absolute filenames
#        and are prefixed  with a leading slash.
#
#        Partial paths look like relative filenames.  They do not begin
#        with a prefix.  The matching rules for partial paths are subtle but
#        designed to make specifying objects easy.  At each level of the
#        composition tree, the partial path is matched as an absolute path.
#        The first match is not returned.  At least two matches are searched
#        for.  A successful result is only returned if only one match is
#        found.  If more than one match is found, a flag is return to
#        indicate that the match was ambiguous.
#
# @property: The property name to read
#
# Returns: The property value.  The type depends on the property
#          type. child<> and link<> properties are returned as #str
#          pathnames.  All integer property types (u8, u16, etc) are
#          returned as #int.
#
# Since: 1.2
#
# Example:
#
# 1. Use absolute path
#
# -> { "execute": "qom-get",
#      "arguments": { "path": "/machine/unattached/device[0]",
#                     "property": "hotplugged" } }
# <- { "return": false }
#
# 2. Use partial path
#
# -> { "execute": "qom-get",
#      "arguments": { "path": "unattached/sysbus",
#                     "property": "type" } }
# <- { "return": "System" }
