Detailed Description

A list of GeoInfos with state flags and out-of-dateness hashes.

Constructor & Destructor Documentation

GeometryList::GeometryList

(

)

Constructor. Initializes the geometry hashes.

Member Function Documentation

unsigned DD::Image::GeometryList::objects ( ) const

inline

Current object count.

unsigned DD::Image::GeometryList::offset ( ) const

inline

Absolute starting index in output list.

GeoOp* DD::Image::GeometryList::geo ( ) const

inline

The GeoOp that is currently manipulating this cache.

Referenced by DD::Image::GeoOp::get_geometry().

unsigned DD::Image::GeometryList::size ( ) const

inline

Object count. Duplicate call to object() for convenience.

void GeometryList::add_object

(

int

obj

)

Add a GeoInfo to the cache.

void GeometryList::delete_objects

(

)

Delete all allocated geometry and clear the cache and output list of objects.

References DD::Image::GeoOp::delete_cache(), and DD::Image::end().

Referenced by DD::Image::ReadGeo::create_geometry().

void GeometryList::synchronize_objects

(

)

Synchronize the local cache object list with the current object list. Calling this repeatedly is cheap as it returns quickly if the cache's build_hash already matches the geo's build hash.

int GeometryList::add_primitive	(	int	obj,
		Primitive *	p = nullptr
	)

Create a local primitive allocation and append a primitive to it if p is non-NULL. Returns the current size of the list.

Return a local writable primitive by index.
