The $obj->getRequiredProperties()Get a list of all the required properties that are needed for this class to properly run its rules.
TRUE $obj->propIsOutput(integer $propertyId)
Check if the property is used in the rules and so can be found from them. This is used in Api.getProperty() to avoid calling the methods in the class if the property that is being looked for cannot be found here.
void $obj->putProperties(string $clientSide)
Merge the tree walk properties with the client side properties and run any additional rules based on the client side and tree walk properties. The rules can define replacement or additional values for properties and can also provide a new User-Agent to be used for a second tree walk. This is typically a fake User-Agent mapped to a device that cannot normally be detected such as the various iPhone models.
