List of all members.


Detailed Description

template<class _ValueType>
class RTT::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:
_ValueType The type of objects you want to have nameserved( usually a pointer type ).

Member Function Documentation

bool isNameRegistered ( const NameType &  s  )  const [inline]

Determine if a given name is registered.

Parameters:
s the name to check
Returns:
true if s is registered, false otherwise

bool isObjectRegistered ( const ValueType  o  )  const [inline]

Determine if a given object is registered.

Parameters:
o the object to check
Returns:
true if o is registered, false otherwise

ValueType getObject ( const NameType &  s  )  const [inline]

Get the object registered for a name.

Parameters:
s the name of the object you need
Returns:
the object the name is registered with, if the name isn't registered, it will return 0

const NameType& getName ( const ValueType  s  )  const [inline]

Get the name registered for a object.

Parameters:
s the object of the name you need
Returns:
the name the object is registered with, if the object isn't registered, it will return 0

bool 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:
obj The instance you wish to register with a name
name The name of the object

void unregisterObject ( const ValueType  obj  )  [inline]

Remove an object from the nameserver registrations.

Parameters:
obj the object you want removed
Postcondition:
obj will not be registered anymore

Todo:
might be improved by using equal_range

void unregisterName ( const NameType &  name  )  [inline]

Remove a name from the nameserver registrations.

Parameters:
name the name of the object you want remove
