class IfcParse::IfcFile¶

This class provides several static convenience functions and variables and provide access to the entities in an IFC file

Subclassed by IfcHierarchyHelper< Schema >

~IfcFile()¶

bool good() const¶

const_iterator begin() const¶: Returns the first entity in the file, this probably is the entity with the lowest id (EXPRESS ENTITY_INSTANCE_NAME)

const_iterator end() const¶: Returns the last entity in the file, this probably is the entity with the highest id (EXPRESS ENTITY_INSTANCE_NAME)

type_iterator types_begin() const¶

type_iterator types_end() const¶

type_iterator types_incl_super_begin() const¶

type_iterator types_incl_super_end() const¶

template<class T> T::list::ptr instances_by_type()¶: Returns all entities in the file that match the template argument. NOTE: This also returns subtypes of the requested type, for example: IfcWall will also return IfcWallStandardCase entities

template<class T> T::list::ptr instances_by_type_excl_subtypes()¶

IfcEntityList::ptr instances_by_type(const IfcParse::declaration*)¶: Returns all entities in the file that match the positional argument. NOTE: This also returns subtypes of the requested type, for example: IfcWall will also return IfcWallStandardCase entities

IfcEntityList::ptr instances_by_type_excl_subtypes(const IfcParse::declaration*)¶: Returns all entities in the file that match the positional argument.

IfcEntityList::ptr instances_by_type(const std::string &t)¶: Returns all entities in the file that match the positional argument. NOTE: This also returns subtypes of the requested type, for example: IfcWall will also return IfcWallStandardCase entities

IfcEntityList::ptr instances_by_type_excl_subtypes(const std::string &t)¶: Returns all entities in the file that match the positional argument.

IfcEntityList::ptr instances_by_reference(int id)¶: Returns all entities in the file that reference the id.

IfcUtil::IfcBaseClass *instance_by_id(int id)¶: Returns the entity with the specified id.

IfcUtil::IfcBaseClass *instance_by_guid(const std::string &guid)¶: Returns the entity with the specified GlobalId.

IfcEntityList::ptr traverse(IfcUtil::IfcBaseClass *instance, int max_level = -1)¶: Performs a depth-first traversal, returning all entity instance attributes as a flat list. NB: includes the root instance specified in the first function argument.

IfcEntityList::ptr getInverse(int instance_id, const IfcParse::declaration *type, int attribute_index)¶

void mark_entity_as_modified(int id)¶

Marks entity as modified so that potential cache for it is invalidated.

Todo:: Currently the whole cache is invalidated. Implement more fine-grained invalidation.

unsigned int FreshId()¶

IfcUtil::IfcBaseClass *addEntity(IfcUtil::IfcBaseClass *entity)¶

void addEntities(IfcEntityList::ptr es)¶

void removeEntity(IfcUtil::IfcBaseClass *entity)¶

Removes entity instance from file and unsets references.

Attention when running removeEntity inside a loop over a list of entities to be removed. This invalidates the iterator. A workaround is to reverse the loop: boost::shared_ptr<IfcEntityList> entities = …; for (auto it = entities->end() - 1; it >= entities->begin(); it) { IfcUtil::IfcBaseClass *const inst = *it; model->removeEntity(inst); }

const IfcSpfHeader &header() const¶
