      • getType

        public java.lang.Class<?> getType()
        Description copied from interface: Expression
        Return the type that this expression will return
        Specified by:
        getType in interface Expression

      • getOpName

        public java.lang.String getOpName()
        Description copied from interface: Expression
        Return a human-readable name for the operation that this expression performs
        Specified by:
        getOpName in interface Expression

      • getChildren

        public Expression[] getChildren()
        Description copied from interface: Expression
        The children (if any) that this expression is dependent on for its execution
        Specified by:
        getChildren in interface Expression

      • connect

        public void connect​(CommonContext context,
                    InteractionListener updateListener)
        Description copied from interface: Expression
        Gives the expression a chance to connect itself to things, if necessary. Most expressions do not have any connections. An expression should notify the updateListener if they change.
        Specified by:
        connect in interface Expression

      • disconnect

        public void disconnect()
        Description copied from interface: Expression
        Tells the expression to disconnect from anything it was connected to.

        disconnect in interface Expression

      • startup

        public void startup()
        Description copied from interface: Expression
        Tells the expression to startup any polling operations. Expressions that use this can remember the updateListener from connect() to feed update notification to.
        Specified by:
        startup in interface Expression

      • shutdown

        public void shutdown()
        Description copied from interface: Expression
