Function Documentation

assignGlobalId()

bool IFCCORE_EXPORT OdIfc::Utils::assignGlobalId

(

OdIfcInstance *

inst

)

Assigns a generated global identifier to the "GlobalId" attribute of an entity derived from an IfcRoot object.

Parameters

pInst

[in] A raw pointer to the IFC entity instance.

Returns

true if the attribute "GlobalId" was successfully assigned; otherwise the method returns false.

getAllRepresentationContexts()

OdDAIObjectIds IFCCORE_EXPORT OdIfc::Utils::getAllRepresentationContexts

(

const OdIfcFile *

pIfcFile

)

Retrieves identifiers (represented with the <exref target="https://docs.opendesign.com/tifc_api_cpp/OdDAIObjectIds.html>OdDAIObjectIds</exref> object) of all IfcGeometricRepresentationContext instances in a model of the specified IFC file. @param pIfcFile [in] A raw pointer to an <exref target="https://docs.opendesign.com/tifc_api_cpp/OdIfcFile.html>OdIfcFile</exref> object that keeps the IFC model.

Returns

An <exref target="https://docs.opendesign.com/tifc_api_cpp/OdDAIObjectIds.html>array of OdDAIObjectId</exref> instances, which contain identifiers that refer to geometric representation context objects; if nothing was selected, the method returns an empty array.

getDefaultRepresentationContextsSelection()

OdDAIObjectIds IFCCORE_EXPORT OdIfc::Utils::getDefaultRepresentationContextsSelection	(	const OdIfcFile *	pIfcFile,
		bool	onlyBody = true )

Retrieves identifiers (represented with the <exref target="https://docs.opendesign.com/tifc_api_cpp/OdDAIObjectIds.html>OdDAIObjectIds</exref> object) of default IfcGeometricRepresentationContext instances, which are necessary to get the geometrical representation of a model of the specified IFC file. @param pIfcFile [in] A raw pointer to an <exref target="https://docs.opendesign.com/tifc_api_cpp/OdIfcFile.html>OdIfcFile</exref> object that keeps the IFC model.

Parameters

onlyBody

[in] A flag that determines that only sub-contexts with the "Body" identifiers are selected (if it is equal to true).

Returns

An <exref target="https://docs.opendesign.com/tifc_api_cpp/OdDAIObjectIds.html>array of OdDAIObjectId</exref> instances, which contain identifiers that refer to geometric representation context objects; if nothing was selected, the method returns an empty array.

Remarks

Earlier IFC versions as IFC2X2 are supported by finding users of contexts.

getParentContainer()

OdDAIObjectId IFCCORE_EXPORT OdIfc::Utils::getParentContainer

(

const OdDAI::ApplicationInstancePtr

instance

)

Retrieves identifier of parent container for IfcElement.

Parameters

instance

[in] A pointer to IFC entity instance.

Returns

The <exref target="https://docs.opendesign.com/tifc_api_cpp/OdDAIObjectId.html>object identifier</exref> of the parent entity or the <<exref target="https://docs.opendesign.com/tifc_api_cpp/OdDAIObjectId__kNullHandle.html>kNullHandle</exref> kNullHandle> value otherwise.

getSubItems()

OdDAIObjectIds IFCCORE_EXPORT OdIfc::Utils::getSubItems

(

const OdDAI::ApplicationInstancePtr

instance

)

Retrieves subitems identifiers of current IfcElement based on decompose or connective relationship.

Parameters

instance

[in] A pointer to IFC application instance.

Returns

OdDAIObjectIds, array of OdDAIObjectId instances, which contain subitems identifiers or empty array otherwise.

getSubItemsByType()

OdDAIObjectIds IFCCORE_EXPORT OdIfc::Utils::getSubItemsByType	(	const OdDAI::ApplicationInstancePtr	instance,
		const OdAnsiString &	subItemType )

Retrieves subitems identifiers of current IfcElement on decompose or connective relationship with specified type.

Parameters

instance	[in] A pointer to IFC application instance.
subItemType	[in] OdAnsiString that contains subitem types to extract.

Returns

OdDAIObjectIds, array of OdDAIObjectId instances, which contain subitems identifiers or empty array otherwise.
