Detailed Description

Base class for all TANGO device since version 2.

This class inherits from DeviceImpl class which itself inherits from CORBA classes where all the network layer is implemented. This class has been created since release 2 of Tango library where the IDL Tango module has been modified in order to create a Device_2 interface which inherits from the original Device interface

Member Function Documentation

command_inout_2()

virtual CORBA::Any* Tango::Device_2Impl::command_inout_2 ( const char *  in_cmd, const CORBA::Any &  in_data, Tango::DevSource  source  )

virtual

Execute a command.

It's the master method executed when a "command_inout_2" CORBA operation is requested by a client. It updates the device black-box, call the TANGO command handler and returned the output Any

Parameters

in_cmd	The command name
in_data	The command input data packed in a CORBA Any
source	The data source. This parameter is new in Tango release 2. It allows a client to choose the data source between the device itself or the data cache for polled command.

Returns

The command output data packed in a CORBA Any object

Exceptions

DevFailed

Re-throw of the exception thrown by the command_handler method. Click here to read DevFailed exception specification

command_inout_history_2()

virtual Tango::DevCmdHistoryList* Tango::Device_2Impl::command_inout_history_2 ( const char *  command, CORBA::Long  n  )

virtual

Read command value history.

Invoked when the client request the command_inout_history_2 CORBA operation. This operation allows a client to retrieve command return value history for polled command. The depth of the history is limited to the depth of the device server internal polling buffer. It returns to the client one DevCmdHistory structure for each record.

Parameters

command	The command name
n	The record number.

Returns

A sequence of DevCmdHistory structure. One structure is initialised for each record with the command return value (in an Any), the date and in case of the command returns an error when it was read, the DevErrors data. Click here to read DevCmdHistory structure definition.

Exceptions

DevFailed

Thrown if the attribute does not exist or is not polled. Click here to read DevFailed exception specification

command_list_query_2()

virtual Tango::DevCmdInfoList_2* Tango::Device_2Impl::command_list_query_2 ( )

virtual

Get device command list.

Invoked when the client request the command_list_query_2 CORBA operation. It updates the device black box and returns an array of DevCmdInfo_2 object with one object for each command.

Returns

The device command list. One DevCmdInfo_2 is initialised for each device command. Since Tango release 2, the command display level field has been added to this structure

command_query_2()

virtual Tango::DevCmdInfo_2* Tango::Device_2Impl::command_query_2 ( const char *  command )

virtual

Get command info.

Invoked when the client request the command_query_2 CORBA operation. It updates the device black box and returns a DevCmdInfo_2 object for the command with name passed to the method as parameter.

Parameters

command

The command name

Returns

A DevCmdInfo_2 initialised for the wanted command.

Exceptions

DevFailed

Thrown if the command does not exist. Since Tango release 2, the command display level field has been added to this structure. Click here to read DevFailed exception specification

get_attribute_config_2()

virtual Tango::AttributeConfigList_2* Tango::Device_2Impl::get_attribute_config_2 ( const Tango::DevVarStringArray &  names )

virtual

Get attribute(s) configuration.

Invoked when the client request the get_attribute_config_2 CORBA operation. It returns to the client one AttributeConfig_2 structure for each wanted attribute. All the attribute properties value are returned in this AttributeConfig_2 structure. Since Tango release 2, the attribute display level field has been added to this structure.

Parameters

names

The attribute(s) name list

Returns

A sequence of AttributeConfig_2 structure. One structure is initialised for each wanted attribute. Click here to read AttributeConfig_2 structure specification.

Exceptions

DevFailed

Thrown if the attribute does not exist. Click here to read DevFailed exception specification

read_attribute_history_2()

virtual Tango::DevAttrHistoryList* Tango::Device_2Impl::read_attribute_history_2 ( const char *  name, CORBA::Long  n  )

virtual

Read attribute value history.

Invoked when the client request the read_attribute_history_2 CORBA operation. This operation allows a client to retrieve attribute value history for polled attribute. The depth of the history is limited to the depth of the device server internal polling buffer. It returns to the client one DevAttrHistory structure for each record.

Parameters

name	The attribute name
n	The record number.

Returns

A sequence of DevAttrHistory structure. One structure is initialised for each record with the attribute value, the date and in case of the attribute returns an error when it was read, the DevErrors data. Click here to read DevAttrHistory structure definition.

Exceptions

DevFailed

Thrown if the attribute does not exist or is not polled. Click here to read DevFailed exception specification

read_attributes_2()

virtual Tango::AttributeValueList* Tango::Device_2Impl::read_attributes_2 ( const Tango::DevVarStringArray &  names, Tango::DevSource  source  )

virtual

Read attribute(s) value.

Invoked when the client request the read_attributes_2 CORBA operation. It returns to the client one AttributeValue structure for each wanted attribute.

Parameters

names	The attribute(s) name list
source	The data source. This parameter is new in Tango release 2. It allows a client to choose the data source between the device itself or the data cache for polled attribute.

Returns

A sequence of AttributeValue structure. One structure is initialised for each wanted attribute with the attribute value, the date and the attribute value quality. Click here to read AttributeValue structure definition.

Exceptions

DevFailed

Thrown if the attribute does not exist. Click here to read DevFailed exception specification
