Member Function Documentation

bool RTT::AttributeRepository::addAttribute

(

AttributeBase *

a

)

[inline]

Add an AttributeBase which remains owned by the user.

Parameters:

a

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

Definition at line 92 of file AttributeRepository.hpp.

bool RTT::AttributeRepository::addConstant

(

AttributeBase *

c

)

[inline]

Add a Constant with a given value.

See also:

getConstant

Definition at line 122 of file AttributeRepository.hpp.

template<class T >

bool RTT::AttributeRepository::addDataObject

(

DataObjectInterface< T > *

doi

)

[inline]

Add a DataObject as an Attribute.

This is especially useful to add the thread-safe DataObjects as thread-safe attributes. You can retrieve it through getValue().

Parameters:

doi

The DataObject, which remains owned by the user.

Returns:

true if doi->getName() is unique within this repository.

Definition at line 190 of file AttributeRepository.hpp.

bool RTT::AttributeRepository::addProperty

(

PropertyBase *

pb

)

Add an PropertyBase as a property.

Returns:

false if a property with the same name already exists.

See also:

removeProperty

AttributeRepository* RTT::AttributeRepository::copy	(	std::map< const DataSourceBase *, 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.

See also:

CommandInterface

Note:

this does not copy the properties() within this repository.

AttributeNames RTT::AttributeRepository::names

(

)

const

Return the names of all attributes.

Deprecated:

by getAttributes()

PropertyBag* RTT::AttributeRepository::properties

(

)

const

Return a bag of all properties.

Returns:

null if none present.

Deprecated:

Properties should no longer be used as a part of the AttributeRepository, but accessed using TaskContext::properties().

bool RTT::AttributeRepository::removeProperty

(

PropertyBase *

p

)

Remove a previously added Property and associated attribute.

Returns:

false if no such property by that name exists.

bool RTT::AttributeRepository::setValue

(

AttributeBase *

ab

)

Transfer the ownership of an attribute to the repository.

Parameters:

ab

The attribute which becomes owned by this repository.

Returns:

false if an Attribute with the same name already present.
