Class DServerClass

java.lang.Object
  fr.esrf.TangoDs.DeviceClass
      fr.esrf.TangoDs.DServerClass

All Implemented Interfaces:

TangoConst

public class DServerClass
extends DeviceClass
implements TangoConst

Class for all data common to all devices of the DServer class. This class is implemented using the singleton design pattern. Therefore a device server process can have only one instance of this class and its constructor is not public.

Method Detail

instance

public static DServerClass instance()

Get the singleton object reference. This method returns a reference to the object of the DServerClass class. If the class has not been initialised with it's init method, this method print a message and abort the device server process

Returns:

The DServerClass object reference

init

public static DServerClass init()
                         throws DevFailed

Create and get the singleton object reference. This method returns a reference to the object of the DServerClass class. If the class singleton object has not been created, it will be instanciated

Returns:

The DServerClass object reference

Throws:

DevFailed - If it is not possible to construct the object. It is a propagation of the xecption thrown by the device_factory method. Click here to read DevFailed exception specification

command_factory

public void command_factory()

Create DServerClass commands. Create one instance of all classes representing command available for device of the DServer class. These commands are QueryDevice, QueryClass, Kill, SetTraceLevel, GetTraceLevel, SetTraceOutput and GetTraceOutput

Specified by:

command_factory in class DeviceClass

device_factory

public void device_factory(java.lang.String[] devlist)
                    throws DevFailed

Create and export device of the DServer class.

Specified by:

device_factory in class DeviceClass

Parameters:

devlist - The device(s) to be created name list

Throws:

DevFailed - If the device creation or export failed. Click here to read DevFailed exception specification
