Detailed Description

template<class _ValueType>
class RTT::dev::NameServer< _ValueType >

A nameserver for Orocos Device classes.

This class allows to globally set up device driver objects and find them back in the same process by querying this class. Every Orocos device driver type has a Device::nameserver type which allows retrieval of the object:

// At application startup code:
Device* init_device = new Device("device_name");
// ...
// In other places:
Device* myDevice = Device::nameserver.getObject("device_name");

In case two objects are registered with the same name, the first one is kept and the second one rejected.

Parameters
_ValueTypeThe type of objects you want to have nameserved( usually a pointer type ).

inline

Determine if a given object is registered.

Parameters
othe object to check

true if o is registered, false otherwise

Definition at line 117 of file NameServer.hpp.

template<class _ValueType>
bool RTT::dev::NameServer< _ValueType >::registerObject ( const ValueType  obj,
const NameType name 
)
inline

Register an object with a name. If an object with such a name already exists, the present one will not be overwritten, and this call is a no-op.

Parameters
objThe instance you wish to register with a name
nameThe name of the object

Definition at line 172 of file NameServer.hpp.

inline

Remove an object from the nameserver registrations.

Parameters
objthe object you want removed
Postcondition
obj will not be registered anymore
Todo:
might be improved by using equal_range
