Detailed Description

IfcGroup is an generalization of any arbitrary group. A group is a logical collection of objects. It does not have its own position, nor can it hold its own shape representation. Therefore a group is an aggregation under some non-geometrical / topological grouping aspects.

EXAMPLE: An example for a group is a system, since it groups elements under the aspect of their role, regardless of their position in a building. One of the most important usage of a group representing a system is the IfcDistributionSystem, that groups distribution components, such as space heaters and valves into a heating system.

A group can hold any collection of objects, the relationship IfcRelAssignsToGroup is used to establish the group collection. Objects within a group are products, processes, controls, resources, actors or other groups, thus groups can be nested. An object can be part of zero, one, or many groups. Grouping relationships are not required to be hierarchical nor do they imply a dependency. Groups are assigned to other objects (such as a process or a resource) by the relationship object that refers to the corresponding object: Process: assigned using IfcRelAssignsToProcess Resource: assigned using IfcRelAssignsToResource Controls: affecting the group using IfcRelAssignsToControl

A group can be exchanged without having already objects within the group collection. IfcGroup does not define an own object coordinate system, nor does it have an independent shape representation.

Member Function Documentation

◆ getAttr() [1/2]

virtual OdRxValue OdIfc2x2_final::IfcObject::getAttr ( const char * attrName ) const

overrideprotectedvirtual

Returns an attribute value for the specified attribute name.

Parameters

attrName [in] Name of an attribute to query.

Returns: OdRxValue object that represents a generic variant type value.

Reimplemented from OdIfc2x2_final::IfcObject.

Reimplemented in OdIfc2x2_final::IfcInventory, OdIfc2x2_final::IfcStructuralAnalysisModel, OdIfc2x2_final::IfcStructuralLoadGroup, OdIfc2x2_final::IfcStructuralResultGroup, and OdIfc2x2_final::IfcSystem.

◆ getAttr() [2/2]

virtual OdRxValue OdIfc2x2_final::IfcGroup::getAttr ( const OdIfc::OdIfcAttribute attrDef ) const

overridevirtual

Returns an attribute value for the specified attribute definition.

Parameters

attrDef [in] Attribute definition to query.

Returns: OdRxValue object that represents a generic variant type value.

Reimplemented from OdIfc2x2_final::IfcObject.

Reimplemented in OdIfc2x2_final::IfcAsset, OdIfc2x2_final::IfcInventory, OdIfc2x2_final::IfcStructuralAnalysisModel, OdIfc2x2_final::IfcStructuralLoadGroup, OdIfc2x2_final::IfcStructuralResultGroup, and OdIfc2x2_final::IfcSystem.

◆ getInstanceType()

virtual OdDAI::Entity * OdIfc2x2_final::IfcGroup::getInstanceType ( ) const

overridevirtual

Returns a type of a class instance.

Returns: Pointer to the <exref target=https://docs.opendesign.com/tkernel_api_cpp/OdDAI__Entity.html>>OdDAI::Entity</exref> type that determines an entity definition within a schema.

Reimplemented from OdIfc2x2_final::IfcObject.

Reimplemented in OdIfc2x2_final::IfcAsset, OdIfc2x2_final::IfcCondition, OdIfc2x2_final::IfcElectricalCircuit, OdIfc2x2_final::IfcInventory, OdIfc2x2_final::IfcStructuralAnalysisModel, OdIfc2x2_final::IfcStructuralLoadGroup, OdIfc2x2_final::IfcStructuralResultGroup, OdIfc2x2_final::IfcSystem, and OdIfc2x2_final::IfcZone.

◆ getInvIsGroupedBy()

OdDAIObjectId OdIfc2x2_final::IfcGroup::getInvIsGroupedBy ( ) const

Returns the value of IsGroupedBy attribute. This attribute represents reference to the relationship IfcRelAssignsToGroup that assigns the one to many group members to the IfcGroup object.

Parameters

IsGroupedBy [out] Receives the value of IsGroupedBy attribute.

Remarks: IFC4 CHANGE: The cardinality has been changed from 1..1 to 0..? in order to allow the exchange of a group concept without having already group members assigned. It now also allows the use of many instances of IfcRelAssignsToGroup to assign the group members. The change has been done with upward compatibility for file based exchange.
