| 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.

| virtual Standard_Boolean | Matches (SelectBasics_SelectingVolumeManager &theMgr, SelectBasics_PickResult &thePickResult) override |
| Checks whether sensitive overlaps current selecting volume. Stores minimum depth, distance to center of geometry and closest point detected into thePickResult. | |

| Returns true if the shape corresponding to the entity has init location. | |
| 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. | |

| Standard_Transient () | |
| Empty constructor. | |

| Returns a true value if this is an instance of TypeName. | |
| 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. | |
| 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. | |
| 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. | |
