Public Member Functions | |
const Handle< SelectMgr_EntityOwner > & | OwnerId () const |
Returns pointer to owner of the entity. More... | |
virtual void | Set (const Handle< SelectMgr_EntityOwner > &theOwnerId) |
Sets owner of the entity. More... | |
Standard_Integer | SensitivityFactor () const |
allows a better sensitivity for a specific entity in selection algorithms useful for small sized entities. More... | |
void | SetSensitivityFactor (const Standard_Integer theNewSens) |
Allows to manage sensitivity of a particular sensitive entity. More... | |
virtual Handle< Select3D_SensitiveEntity > | GetConnected () |
Originally this method intended to return sensitive entity with new location aLocation, but currently sensitive entities do not hold a location, instead HasLocation() and Location() methods call corresponding entity owner's methods. Thus all entities returned by GetConnected() share the same location propagated from corresponding selectable object. You must redefine this function for any type of sensitive entity which can accept another connected sensitive entity. More... | |
virtual Standard_Boolean | Matches (SelectBasics_SelectingVolumeManager &theMgr, SelectBasics_PickResult &thePickResult)=0 |
Checks whether sensitive overlaps current selecting volume. Stores minimum depth, distance to center of geometry and closest point detected into thePickResult. More... | |
virtual Standard_Integer | NbSubElements () const =0 |
Returns the number of sub-entities or elements in sensitive entity. Is used to determine if entity is complex and needs to pre-build BVH at the creation of sensitive entity step or is light-weighted so the tree can be build on demand with unnoticeable delay. More... | |
virtual Select3D_BndBox3d | BoundingBox ()=0 |
Returns bounding box of a sensitive with transformation applied. More... | |
virtual gp_Pnt | CenterOfGeometry () const =0 |
Returns center of a sensitive with transformation applied. More... | |
virtual void | BVH () |
Builds BVH tree for a sensitive if needed. More... | |
virtual Standard_Boolean | ToBuildBVH () const |
Returns TRUE if BVH tree is in invalidated state. More... | |
virtual void | Clear () |
Clears up all resources and memory. More... | |
virtual Standard_Boolean | HasInitLocation () const |
Returns true if the shape corresponding to the entity has init location. More... | |
virtual gp_GTrsf | InvInitLocation () const |
Returns inversed location transformation matrix if the shape corresponding to this entity has init location set. Otherwise, returns identity matrix. More... | |
virtual void | DumpJson (Standard_OStream &theOStream, Standard_Integer theDepth=-1) const |
Dumps the content of me into the stream. More... | |
Public Member Functions inherited from Standard_Transient | |
Standard_Transient () | |
Empty constructor. More... | |
Standard_Transient (const Standard_Transient &) | |
Copy constructor – does nothing. More... | |
Standard_Transient & | operator= (const Standard_Transient &) |
Assignment operator, needed to avoid copying reference counter. More... | |
virtual | ~Standard_Transient () |
Destructor must be virtual. More... | |
virtual void | Delete () const |
Memory deallocator for transient classes. More... | |
virtual const opencascade::handle< Standard_Type > & | DynamicType () const |
Returns a type descriptor about this object. More... | |
Standard_Boolean | IsInstance (const opencascade::handle< Standard_Type > &theType) const |
Returns a true value if this is an instance of Type. More... | |
Standard_Boolean | IsInstance (const Standard_CString theTypeName) const |
Returns a true value if this is an instance of TypeName. More... | |
Standard_Boolean | IsKind (const opencascade::handle< Standard_Type > &theType) const |
Returns true if this is an instance of Type or an instance of any class that inherits from Type. Note that multiple inheritance is not supported by OCCT RTTI mechanism. More... | |
Standard_Boolean | IsKind (const Standard_CString theTypeName) const |
Returns true if this is an instance of TypeName or an instance of any class that inherits from TypeName. Note that multiple inheritance is not supported by OCCT RTTI mechanism. More... | |
Standard_Transient * | This () const |
Returns non-const pointer to this object (like const_cast). For protection against creating handle to objects allocated in stack or call from constructor, it will raise exception Standard_ProgramError if reference counter is zero. More... | |
Standard_Integer | GetRefCount () const |
Get the reference counter of this object. More... | |
void | IncrementRefCounter () const |
Increments the reference counter of this object. More... | |
Standard_Integer | DecrementRefCounter () const |
Decrements the reference counter of this object; returns the decremented value. More... | |
