class | GeoOp |
A list of GeoInfos with state flags and out-of-dateness hashes.
GeometryList::GeometryList | ( | ) |
Constructor. Initializes the geometry hashes.
|
inline |
Current object count.
|
inline |
Absolute starting index in output list.
|
inline |
The GeoOp that is currently manipulating this cache.
Referenced by DD::Image::GeoOp::get_geometry().
|
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.
