These types are mapped to the appropriate JSON 26# type. 27# 28# 2) A child type in the form 'child<subtype>' where subtype is a 29# qdev device type name.

There are two forms of 83# supported paths--absolute and partial paths. 84# 85# Absolute paths are derived from the root object and can follow 86# child<> or link<> properties. Since they can follow link<> 87# properties, they can be arbitrarily long. Absolute paths look 88# like absolute filenames and are prefixed with a leading slash. 89# 90# Partial paths look like relative filenames. They do not begin 91# with a prefix. The matching rules for partial paths are subtle 92# but designed to make specifying objects easy. At each level of 93# the composition tree, the partial path is matched as an absolute 94# path. The first match is not returned. At least two matches 95# are searched for. A successful result is only returned if only 96# one match is found. If more than one match is found, a flag is 97# return to indicate that the match was ambiguous. 98# 99# @property: The property name to read 100# 101# Returns: The property value. The type depends on the property type. 102# child<> and link<> properties are returned as #str pathnames. 103# All integer property types (u8, u16, etc) are returned as #int. 104# 105# Since: 1.2 106# 107# Examples: 108# 109# 1.
