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 (  )  [inline]

Create a Constant with no name and no value.

Definition at line 258 of file Attribute.hpp.

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

Create a constant with a fixed value t.

Parameters:
name The name of this instance.
t The 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:
name The name of this instance.
t The value for initialisation.
o The owner, which has a function 'addAttribute(AttributeBase*)'.

Definition at line 283 of file Attribute.hpp.

template<typename T>
RTT::Constant< T >::Constant ( const std::string &  name,
internal::DataSource< T > *  d 
) [inline]

Create a constant wich holds a internal::DataSource d.

Definition at line 293 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:
ab The 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 >::clone (  )  const [inline, virtual]

Returns a clone of this AttributeBase.

Implements RTT::base::AttributeBase.

Definition at line 354 of file Attribute.hpp.

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

Definition at line 359 of file Attribute.hpp.

template<typename T>
T RTT::Constant< T >::get (  )  const [inline]

Get the value of this Constant.

Definition at line 344 of file Attribute.hpp.

template<typename T>
base::DataSourceBase::shared_ptr RTT::Constant< T >::getDataSource (  )  const [inline, virtual]

Return a internal::DataSource which contains the same contents.

Implements RTT::base::AttributeBase.

Definition at line 349 of file Attribute.hpp.

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:
ab The 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.
