Detailed Description

A class for keeping track of Attribute, Constant and Property objects of a TaskContext.

It allows plugins and remote components to browse the attributes and properties of a TaskContext.

Member Function Documentation

template<class T >

bool RTT::ConfigurationInterface::addAttribute	(	const std::string &	name,
		T &	attr
	)		`[inline]`

Adds a variable of any type as read/write attribute to the configuration interface.

An Alias is created which causes contents of the attr variable always to be in sync with the contents of the attribute object in the interface.

Parameters:

name	The name of this attribute
attr	The variable that will be aliased.

Definition at line 101 of file ConfigurationInterface.hpp.

template<class T >

Attribute<T>& RTT::ConfigurationInterface::addAttribute	(	const std::string &	name,
		Attribute< T > &	attr
	)		`[inline]`

Adds an existing attribute object to the configuration interface.

Parameters:

name	The name of this attribute. attr will be initialized with this name.
attr	The attribute to add

Returns:: the Attribute object by reference, which you can further query or use.

Postcondition:: attr.ready() == true

Definition at line 115 of file ConfigurationInterface.hpp.

References RTT::base::AttributeBase::ready(), and RTT::base::AttributeBase::setName().

bool RTT::ConfigurationInterface::addAttribute ( base::AttributeBase & a ) [inline]

Add an base::AttributeBase which remains owned by the user.

This is a low-level function that can be used if you already created an Attribute object that does not belong yet to a service.

Parameters:

a	remains owned by the user, and becomes served by the repository.

template<class T >

bool RTT::ConfigurationInterface::addConstant	(	const std::string &	name,
		const T &	cnst
	)		`[inline]`

Adds a variable of any type as read-only attribute to the configuration interface.

An Alias is created which causes contents of the attribute always to be in sync with the contents of cnst, but it can only be read through the interface.

Parameters:

name	The name of this attribute
cnst	The variable that will be aliased.

Definition at line 135 of file ConfigurationInterface.hpp.

template<class T >

Constant<T>& RTT::ConfigurationInterface::addConstant	(	const std::string &	name,
		Constant< T > &	cnst
	)		`[inline]`

Adds an existing constant object to the configuration interface.

Parameters:

name	The name of this constant. cnst will be initialized with this name.
cnst	The constant to add. If cnst has not been initialized, it will be initialized to T(). You can change it later-on using the Constant's API.

Returns:: the Constant object by reference, which you can further query or use.

Postcondition:: cnst.ready() == true

Definition at line 150 of file ConfigurationInterface.hpp.

References RTT::base::AttributeBase::ready(), and RTT::base::AttributeBase::setName().

bool RTT::ConfigurationInterface::addConstant ( base::AttributeBase & c ) [inline]

Add a Constant with a given value.

template<class T >

Property<T>& RTT::ConfigurationInterface::addProperty	(	const std::string &	name,
		T &	prop
	)		`[inline]`

Adds a variable of any type as a property to the configuration interface.

A Property is created which causes contents of the property always to be in sync with the contents of prop.

Parameters:

name	The name of this property
prop	The variable that will be aliased.

Returns:: the Property object by reference, which you can further query or document.

Definition at line 171 of file ConfigurationInterface.hpp.

template<class T >

Property<T>& RTT::ConfigurationInterface::addProperty	(	const std::string &	name,
		Property< T > &	prop
	)		`[inline]`

Adds an existing property object to the configuration interface.

Parameters:

name	The name of this property. prop will be initialized with this name.
prop	The property to add

Returns:: the Property object by reference, which you can further query or document.

Postcondition:: prop.ready() == true

Definition at line 184 of file ConfigurationInterface.hpp.

References RTT::base::PropertyBase::ready(), and RTT::base::PropertyBase::setName().

bool RTT::ConfigurationInterface::addProperty ( base::PropertyBase & pb )

Add an base::PropertyBase as a property.

Returns:: false if a property with the same name already exists.

ConfigurationInterface * RTT::ConfigurationInterface::copy	(	std::map< const base::DataSourceBase , base::DataSourceBase > &	repl,
		bool	instantiate
	)		const

Return a new copy of this repository with the copy operation semantics.

Parameters:

instantiate set to true if you want a copy which will upon any future copy return the same DataSources, thus 'fixating' or 'instantiating' the DataSources.
