Detailed Description

Event and asynchronous (callback model) calls base class.

When using the event push model (callback automatically executed), there are some cases (same callback used for events coming from different devices hosted in device server process running on different hosts) where the callback method could be executed concurently by different threads started by the ORB. The user has to code his callback method in a thread safe manner.

attr_read()

virtual void Tango::CallBack::attr_read ( AttrReadEvent *  are )

inlinevirtual

Asynchronous read attribute execution callback method.

This method is defined as being empty and must be overloaded by the user when the asynchronous callback model is used. This is the method which will be executed when the server reply from a read_attribute(s) is received in both push and pull sub-mode.

Parameters

are	The read attribute data

attr_written()

virtual void Tango::CallBack::attr_written ( AttrWrittenEvent *  awe )

inlinevirtual

Asynchronous write attribute execution callback method.

This method is defined as being empty and must be overloaded by the user when the asynchronous callback model is used. This is the method which will be executed when the server reply from a write_attribute(s) is received in both push and pull sub-mode.

Parameters

awe	The write attribute data

cmd_ended()

virtual void Tango::CallBack::cmd_ended ( CmdDoneEvent *  cde )

inlinevirtual

Asynchronous command execution callback method.

This method is defined as being empty and must be overloaded by the user when the asynchronous callback model is used. This is the method which will be executed when the server reply from a command_inout is received in both push and pull sub-mode.

Parameters

cde	The command data

push_event() [1/5]

virtual void Tango::CallBack::push_event ( AttrConfEventData *  ace )

inlinevirtual

attribute configuration change event callback method

This method is defined as being empty and must be overloaded by the user when events are used. This is the method which will be executed when the server send attribute configuration change event(s) to the client.

Parameters

ace	The attribute configuration change event data

push_event() [2/5]

virtual void Tango::CallBack::push_event ( DataReadyEventData *  dre )

inlinevirtual

Data ready event callback method.

This method is defined as being empty and must be overloaded by the user when events are used. This is the method which will be executed when the server send attribute data ready event(s) to the client.

Parameters

dre	The data ready event data

push_event() [3/5]

virtual void Tango::CallBack::push_event ( DevIntrChangeEventData *  dic )

inlinevirtual

Device interface change event callback method.

This method is defined as being empty and must be overloaded by the user when events are used. This is the method which will be executed when the server send device interface change event(s) to the client.

Parameters

dic	The device interface change event data

push_event() [4/5]

virtual void Tango::CallBack::push_event ( EventData *  ed )

inlinevirtual

Event callback method.

This method is defined as being empty and must be overloaded by the user when events are used. This is the method which will be executed when the server send event(s) to the client.

Parameters

ed	The event data

push_event() [5/5]

virtual void Tango::CallBack::push_event ( PipeEventData *  ped )

inlinevirtual

Pipe event callback method.

This method is defined as being empty and must be overloaded by the user when events are used. This is the method which will be executed when the server send pipe event(s) to the client.

Parameters

ped	The pipe event data
