Class DeviceParameter

java.lang.Object
com.iizix.device.DeviceParameter
Direct Known Subclasses:
DeviceAutoSignIn
public sealed class DeviceParameter extends Object permits DeviceAutoSignIn
Class used to send parameters between the server and the client. Support for sensitive information by means of encryption is supported. Parameters that are sensitive are stored in a secure space on the client side.

This class is not thread safe and gets the value and state updated in calls to the method to set to retrieve parameters.

Valid parameter name

The valid name of a device parameter are the characters A-Z, a-z, 0-9 and any of the following characters !#$%&*+-^_`|~. Please note that the single or double-quotes are not allowed. The name must start with a character A-Z, a-z or 0-9. The name must also have a length of 1 to 64 characters.
