		T	t
	)			[inline, explicit]

Create an Attribute with a name and a given value t.

Parameters:

	name	The name of this instance.
	t	The value for initialisation.

Attribute	(	const std::string &	name,
		AssignableDataSource< T > *	d
	)			[inline]

Attribute

(

AttributeBase *

ab

)

[inline]

Create an Attribute which mirrors a AttributeBase ab.

If successful, this attribute will always have the same value as ab and vice versa.

Parameters:

ab

The Attribute to mirror.

See also:

ready() to check if ab was accepted.

Member Function Documentation

Attribute<T>& operator=

(

AttributeBase *

ab

)

[inline]

Initialise an Attribute which mirrors an AttributeBase ab.

If successful, this attribute will always have the same value as ab and vice versa.

See also:

ready() to check if ab was accepted.

Attribute<T>* copy	(	std::map< const DataSourceBase *, DataSourceBase * > &	replacements,
		bool	instantiate
	)			[inline, virtual]

Returns a copy of this AttributeBase.

Uses the given replacements to copy held DataSources.

Parameters:

instantiate

Set to true to get a copy which will return itself on any future copy request.

Implements AttributeBase.
