template <typename T>auto Get (const PropertyName & name)Gets the parsed value for a property named `name`, cast to type `T`.
Returns an `std::optional
<T
>` containing the value if the property exists
and can be cast to `T`. Otherwise, returns `std::nullopt`.
Example usage:
To get a single string property:
auto str_prop = props.Get
<std
::string>("string-property");
To get an array of uint32s:
auto arr_prop = props.Get
<std
::vector
<uint32
_t>>("uint32-array-property");
To get a list of references:
auto ref_prop = props.Get
<fdf
_devicetree::References>("reference-property");
if (ref_prop) {
for (const auto
&
ref : *ref_prop) {
// process reference
}
A special case is provided for `bool`. `Get
<bool
>("property-name")` will
return `true` if the property exists and is true, and `false` otherwise
(if it does not exist or is false).
