Detailed Description

General Attribute class.

Constructor & Destructor Documentation

DD::Image::Attribute::Attribute ( const Attribute & src )

inline

Copy constructor.

Attribute::Attribute	(	const char *	name,
		AttribType	type,
		size_t	size = `0`
	)

Basic constructor requires a name and type. Size is defaulted to 0.

Member Function Documentation

Attribute & Attribute::operator= ( const Attribute & b )

Assignment operator. Empty then copy all data from 'b' into this.

void Attribute::copy	(	int	dest,
		const Attribute &	b,
		int	b_start
	)

Destructively copy a single item from 'b_start' to 'dest'.

void Attribute::copy	(	int	dest,
		const Attribute &	b,
		int	b_start,
		int	b_end
	)

Destructively copy a range of items from 'b' to a range beginning at 'dest'.

bool Attribute::append	(	const Attribute &	b,
		int	b_start
	)

Appends data elements from a same type Attribute onto the end of this one. Fails if both types are not the same.

bool Attribute::append	(	const Attribute &	b,
		int	b_start,
		int	b_end
	)

Appends a range of elements from a same type Attribute onto the end of this one. Fails if both types are not the same.

References array(), size(), and type_.

unsigned Attribute::size ( ) const

Number of data elements in list.

Referenced by DD::Image::GeometryList::add_primitive(), append(), copy(), and DD::Image::GeoOp::evaluate_transform().

void Attribute::add ( unsigned n = 1 )

Add 'n' elements to end of list.

Referenced by DD::Image::GeometryList::add_primitive().

void Attribute::reserve ( unsigned size )

Reserve memory in list for 'n' elements. If you already know the maximum size of the attribute, this can save a lot of overhead if you call this before adding single elements.
