Class EnvProps

  • All Implemented Interfaces:
    EventListener, IGProp<GProp<?>[]>, IPropCnr, java.lang.Cloneable
    public class EnvProps
extends PropCnr
    This client property is a container that holds everything a client/server needs in order to establish communication with the other party, and information about themselves (such as environment).

    The property also handles the capabilities of the client.

    The environment has at least the following properties:

    • $client - StringMapProp
    • $server - StringMapProp
    • $geo - GeoProps
    • ...other capabilities such as Speech...

      • addPredefinedProps

        protected void addPredefinedProps()
                           throws PropException
        Adds the predefined properties for this container. This method is called once just after construction of the property container.

        Properties added:

          - client environment  StringMapProp  Atom.A_CLIENT
  - server environment  StringMapProp  Atom.A_SERVER

        Overrides:
        addPredefinedProps in class PropCnr
        Throws:
        PropException - for property exceptions.

      • getPredefinedProps

        protected void getPredefinedProps()
        Gets potential references to predefined properties for this container. This method is called once just after cloning of the property container.

        The method should get reference to using the getProp(...) methods. This allows the subclass to be able to retrieve the new instances to the properties created during addPredefinedProps() if stored in instance variables.

        Overrides:
        getPredefinedProps in class PropCnr

      • getServerEnv

        public StringMapProp getServerEnv()
        Gets the server environment properties.
        Returns:
        StringMapProp for the server environment.

      • getClientEnv

        public StringMapProp getClientEnv()
        Gets the client environment properties.
        Returns:
        StringMapProp for the client environment.

      • iiziRunPresent

        public boolean iiziRunPresent()
        Checks if iiziRun is present.

        Changes or sets the LocaleInfo for the environment. This method is intended to be used to change the language setting of a client session.

        Note that this change does not fire any refresh to the client property tree, use the IClientSessionGyro.setLocale(LocaleInfo) instead.

        Parameters:
        locale - localeInfo The locale information to use.
