A framework to define a filter to select a specific type of edge. The types available include: More...
#include <StdSelect_EdgeFilter.hxx>
Public Member Functions | |
| StdSelect_EdgeFilter (const StdSelect_TypeOfEdge Edge) | |
| Constructs an edge filter object defined by the type of edge Edge. | |
| void | SetType (const StdSelect_TypeOfEdge aNewType) |
| Sets the type of edge aNewType. aNewType is to be highlighted in selection. | |
| StdSelect_TypeOfEdge | Type () const |
| Returns the type of edge to be highlighted in selection. | |
| bool | IsOk (const occ::handle< SelectMgr_EntityOwner > &anobj) const override |
| Indicates that the selected Interactive Object passes the filter. The owner, anObj, can be either direct or user. A direct owner is the corresponding construction element, whereas a user is the compound shape of which the entity forms a part. When an object is detected by the mouse - in AIS, this is done through a context selector - its owner is passed to the filter as an argument. If the object returns true, it is kept; if not, it is rejected. If you are creating a filter class inheriting this framework, and the daughter class is to be used in an AIS local context, you will need to implement the virtual function ActsOn. | |
| bool | ActsOn (const TopAbs_ShapeEnum aStandardMode) const override |
| Returns true in an AIS local context, if this filter operates on a type of subshape defined in a filter class inheriting this framework. This function completes IsOk in an AIS local context. | |
 Public Member Functions inherited from Standard_Transient | |
| Standard_Transient () | |
| Empty constructor. | |
| Standard_Transient (const Standard_Transient &) | |
| Copy constructor – does nothing. | |
| Standard_Transient & | operator= (const Standard_Transient &) |
| Assignment operator, needed to avoid copying reference counter. | |
| virtual | ~Standard_Transient ()=default |
| Destructor must be virtual. | |
| virtual const opencascade::handle< Standard_Type > & | DynamicType () const |
| Returns a type descriptor about this object. | |
| bool | IsInstance (const opencascade::handle< Standard_Type > &theType) const |
| Returns a true value if this is an instance of Type. | |
| bool | IsInstance (const char *const theTypeName) const |
| Returns a true value if this is an instance of TypeName. | |
| bool | 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. | |
| bool | IsKind (const char *const 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. | |
| int | GetRefCount () const noexcept |
| Get the reference counter of this object. | |
| void | IncrementRefCounter () noexcept |
| Increments the reference counter of this object. Uses relaxed memory ordering since incrementing only requires atomicity, not synchronization with other memory operations. | |
| int | DecrementRefCounter () noexcept |
| Decrements the reference counter of this object; returns the decremented value. Uses release ordering for the decrement to ensure all writes to the object are visible before the count reaches zero. An acquire fence is added only when the count reaches zero, ensuring proper synchronization before deletion. This is more efficient than using acq_rel for every decrement. | |
| virtual void | Delete () const |
| Memory deallocator for transient classes. | |
Additional Inherited Members | |
| Public Types inherited from Standard_Transient | |
| typedef void | base_type |
| Returns a type descriptor about this object. | |
| Static Public Member Functions inherited from Standard_Transient | |
| static constexpr const char * | get_type_name () |
| Returns a type descriptor about this object. | |
| static const opencascade::handle< Standard_Type > & | get_type_descriptor () |
| Returns type descriptor of Standard_Transient class. | |
A framework to define a filter to select a specific type of edge. The types available include:
| StdSelect_EdgeFilter::StdSelect_EdgeFilter | ( | const StdSelect_TypeOfEdge | Edge | ) |
Constructs an edge filter object defined by the type of edge Edge.
|
overridevirtual |
Returns true in an AIS local context, if this filter operates on a type of subshape defined in a filter class inheriting this framework. This function completes IsOk in an AIS local context.
Reimplemented from SelectMgr_Filter.

overridevirtual |
Indicates that the selected Interactive Object passes the filter. The owner, anObj, can be either direct or user. A direct owner is the corresponding construction element, whereas a user is the compound shape of which the entity forms a part. When an object is detected by the mouse - in AIS, this is done through a context selector - its owner is passed to the filter as an argument. If the object returns true, it is kept; if not, it is rejected. If you are creating a filter class inheriting this framework, and the daughter class is to be used in an AIS local context, you will need to implement the virtual function ActsOn.
Implements SelectMgr_Filter.
| void StdSelect_EdgeFilter::SetType | ( | const StdSelect_TypeOfEdge | aNewType | ) |
Sets the type of edge aNewType. aNewType is to be highlighted in selection.
| StdSelect_TypeOfEdge StdSelect_EdgeFilter::Type | ( | ) | const |
Returns the type of edge to be highlighted in selection.
