#include <TDF_AttributeDelta.hxx>
Public Member Functions | |
virtual void | Apply ()=0 |
Applies the delta to the attribute. More... | |
TDF_Label | Label () const |
Returns the label concerned by <me>. More... | |
Handle< TDF_Attribute > | Attribute () const |
Returns the reference attribute. More... | |
Standard_GUID | ID () const |
Returns the ID of the attribute concerned by <me>. More... | |
virtual Standard_OStream & | Dump (Standard_OStream &OS) const |
Dumps the contents. More... | |
Standard_OStream & | operator<< (Standard_OStream &OS) const |
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... | |
Protected Member Functions | |
TDF_AttributeDelta (const Handle< TDF_Attribute > &anAttribute) | |
Additional Inherited Members | |
Public Types inherited from Standard_Transient | |
typedef void | base_type |
Returns a type descriptor about this object. More... | |
Static Public Member Functions inherited from Standard_Transient | |
static const char * | get_type_name () |
Returns a type descriptor about this object. More... | |
static const opencascade::handle< Standard_Type > & | get_type_descriptor () |
Returns type descriptor of Standard_Transient class. More... | |
This class discribes the services we need to implement Delta and Undo/Redo services.
AttributeDeltas are applied in an unpredictable order. But by the redefinition of the method IsNowApplicable, a condition can be verified before application. If the AttributeDelta is not yet applicable, it is put at the end of the AttributeDelta list, to be treated later. If a dead lock if found on the list, the AttributeDeltas are forced to be applied in an unpredictable order.
