Detailed Description

A range of elements in an index-map.

A range specifies a selection/collection of elements in an index map for iteration. The membership state of individual elements can also be queried (

See Also: allocMemberQuery()).

Iteration over a range, performed by instantiating a GA_Iterator, does not affect the range object itself. The begin() method can be used to initialize a basic iterator.

Custom range types are implemented by subclassing GA_RangeTypeInterface.

Examples:: SOP/SOP_BrushHairLen.C, and tetprim/GEO_PrimTetra.C.

GA_Range::GA_Range	(	const GA_Range &	src,

GA_Range::GA_Range	(	const GA_IndexMap &	map,
		const GA_OffsetList &	offsetlist,
		GA_Size	start = `0`,
		GA_Size	end = `-1`
	)

Constructor to create a range containing the offsets in the given list. If end < 0, it will be set to the offsetlist.entries()

See Also: GA_RTIOffsetList

GA_Range::GA_Range	(	const GA_ElementGroup &	group,
		bool	complement = `false`
	)

explicit

Construct a range of the elements in a given group

See Also: GA_RTIElementGroup

GA_Range::GA_Range	(	const GA_IndexMap &	map,
		const GA_ElementGroup *	group,
		bool	complement = `false`
	)

Construct a range of the elements in a given group

See Also: GA_RTIElementGroup

GA_Range::GA_Range	(	const GA_ElementGroup &	group,
		ignore_order	,
		bool	complement = `false`
	)

Construct a range of the elements in a given group, ignoring its order even if it is ordered.

See Also: GA_RTIElementGroup

GA_Range::GA_Range	(	const GA_IndexMap &	map,
		const GA_ElementGroup *	group,
		ignore_order	,
		bool	complement = `false`
	)

Construct a range of the elements in a given group, ignoring its order even if it is ordered.

See Also: GA_RTIElementGroup

GA_Range::GA_Range	(	const GA_Detail &	geo,
		GA_Offset	point,
		GA_AttributeOwner	owner,
		pointref	,
		bool	harden
	)

Construct a range of all the elements referencing a given point. The harden argument determines whether it is safe to use this range after the point has been deleted. If the point will exist for the lifetime of the range, harden can be false and thus more efficient.

For example, to find all the vertices which reference point number 3:

GA_Range(geo, 3, GA_ATTRIB_VERTEX, GA_Range::pointref, false);

See Also: GA_RTIPointRef

GA_Range::GA_Range	(	const GA_Detail &	geo,
		const GA_Range &	point_range,
		GA_AttributeOwner	type,
		pointref	,
		bool	harden
	)

Construct a range of all primitives/vertices referenced by the points in the given range. The harden argument determines whether it is safe to use this range after the point has been deleted. If the point will exist for the lifetime of the range, harden can be false and thus more efficient.

GA_Range(geo, geo.getPointRange(), GA_ATTRIB_PRIMITIVE, false);

GA_Range(geo, geo.getPointRange(), GA_ATTRIB_VERTEX, false);

See Also: GA_RTIPointComprehension

GA_Range::GA_Range	(	const GA_Detail &	geo,
		GA_Offset	prim,
		GA_AttributeOwner	owner,
		primitiveref	,
		bool	harden
	)

Construct a range of all the elements used by a given primitive. The harden argument determines whether it is safe to use this range after the primitive has been deleted. If the primitive will exist for the lifetime of the range, harden can be false, and thus more efficient. If vertices are added or removed during traversal and harden is true, only the original vertices will be traversed, but behaviour is undefined if harden is false.

For example, to find all the points which referenced by primitive 3:

GA_Range(geo, 3, GA_ATTRIB_VERTEX, GA_Range::primitiveref);

See Also: GA_RTIPrimitiveRef

GA_Range::GA_Range	(	const GA_Detail &	geo,
		const GA_Range &	primitive_range,
		GA_AttributeOwner	type,
		primitiveref	,
		bool	harden
	)

Construct a range of all points/vertices referenced by the primitives in the given range. The harden argument determines whether it is safe to use this range after the primitive has been deleted. If the primitive will exist for the lifetime of the range, harden can be false and thus more efficient.

GA_Range(geo, geo.getPrimitiveRange(), GA_ATTRIB_POINT);

GA_Range(geo, geo.getPrimitiveRange(), GA_ATTRIB_VERTEX);

See Also: GA_RTIPrimitiveComprehension

GA_Range::GA_Range	(	const GA_Detail &	geo,
		const GA_Range &	primitive_range,
		GA_AttributeOwner	type,
		primitiveref	,
		ordered	,
		bool	harden
	)

Construct a range of all points/vertices referenced by the primitives in the given range. The harden argument determines whether it is safe to use this range after the primitive has been deleted. If the primitive will exist for the lifetime of the range, harden can be false and thus more efficient.

This version delivers the points/vertices in the order imposed by the primitive_range. This is equivalent to traversing the vertices of each primitive with a GA_Primitive::const_iterator as it is visited.

GA_Range(geo, geo.getPrimitiveRange(), GA_ATTRIB_POINT);

GA_Range(geo, geo.getPrimitiveRange(), GA_ATTRIB_VERTEX);

See Also: GA_RTIPrimitiveComprehension

GA_Range::GA_Range	(	const GA_IndexMap &	map,
		includetemporaries
	)

Iterate over all elements in the index map, including any temporary elements. This should be used within ATI's when changing data for all elements (including temporaries).

Member Function Documentation

void GA_Range::adopt ( GA_RangeTypeInterface * r )

inline

Take ownership of the given GA_RangeTypeInterface. This is used to avoid unnecessary calls to GA_RangeTypeInterface::copy().

Definition at line 237 of file GA_Range.h.

const GA_RangeMemberQuery* GA_Range::allocMemberQuery ( ) const

Allocate an object for testing the membership of individual elements to this range. The caller is responsible for deleting this object, which should not outlive the allocating range.

Behaviour of this object is undefined for any elements that have been deleted or moved since its creation.

bool GA_Range::areTraversalDeletionsSafe ( ) const

GA_Iterator GA_Range::begin ( ) const

Default iterator
