Detailed Description

template<typename T>
class RTT::Constant< T >

As opposed to a Attribute, a Constant can not be assigned to a new value after creation.

Definition at line 249 of file Attribute.hpp.


Constructor & Destructor Documentation

template<typename T>
RTT::Constant< T >::Constant ( const std::string &  name,
t 
) [inline]

Create a constant with a fixed value t.

Parameters:
nameThe name of this instance.
tThe value for initialisation.

Definition at line 267 of file Attribute.hpp.

template<typename T>
template<class Owner >
RTT::Constant< T >::Constant ( const std::string &  name,
t,
Owner  owner 
) [inline]

Create a constant with a fixed value t and an owner.

The owner is used to register this attribute to and is supposed to be a pointer (or shared pointer).

Parameters:
nameThe name of this instance.
tThe value for initialisation.
oThe owner, which has a function 'addAttribute(AttributeBase*)'.

Definition at line 283 of file Attribute.hpp.

template<typename T>
RTT::Constant< T >::Constant ( base::AttributeBase ab) [inline]

Create a constant which mirrors an Attribute.

If successful, this constant will always have the same value as ab.

Parameters:
abThe attribute to mirror. If null, this will clear this attribute and clear its name.
See also:
ready() to check if ab was accepted.

Definition at line 307 of file Attribute.hpp.


Member Function Documentation

template<typename T>
Constant<T>* RTT::Constant< T >::copy ( std::map< const base::DataSourceBase *, base::DataSourceBase * > &  replacements,
bool  instantiate 
) [inline, virtual]

Returns a copy of this AttributeBase.

Uses the given replacements to copy held DataSources.

Parameters:
instantiateSet to true to get a copy which will return itself on any future copy request.

Implements RTT::base::AttributeBase.

Definition at line 359 of file Attribute.hpp.

const std::string & RTT::AttributeBase::getName ( ) const [inherited]
template<typename T>
Constant<T>& RTT::Constant< T >::operator= ( base::AttributeBase ab) [inline]

Initialise an Attribute which mirrors an AttributeBase.

If successful, this constant will always have the same value as ab.

Parameters:
abThe attribute to mirror. If null, this will clear this attribute and clear its name.
See also:
ready() to check if ab was accepted.

Definition at line 321 of file Attribute.hpp.

void RTT::AttributeBase::setName ( std::string const &  new_name) [inherited]

Get the name of this instance.

Returns:
the name
