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.

Detailed Description

This is a relocation dictionary between source and target labels, attributes or any transient(useful for copy or paste actions). Note that one target value may be the relocation value of more than one source object.

Common behaviour: it returns true and the found relocation value as target object; false otherwise.

Look at SelfRelocate method for more explanation about self relocation behavior of this class.

Constructor & Destructor Documentation

◆ TDF_RelocationTable()

TDF_RelocationTable::TDF_RelocationTable ( const bool selfRelocate = false )

Creates an relocation table. <selfRelocate> says if a value without explicit relocation is its own relocation.

Member Function Documentation

◆ AfterRelocate() [1/2]

bool TDF_RelocationTable::AfterRelocate ( ) const

Returns <myAfterRelocate>.

◆ AfterRelocate() [2/2]

void TDF_RelocationTable::AfterRelocate ( const bool afterRelocate )

◆ AttributeTable()

NCollection_DataMap< occ::handle< TDF_Attribute >, occ::handle< TDF_Attribute > > & TDF_RelocationTable::AttributeTable ( )

Returns <myAttributeTable> to be used or updated.

◆ Clear()

void TDF_RelocationTable::Clear ( )

Clears the relocation dictionary, but lets the self relocation flag to its current value.

◆ Dump()

Standard_OStream & TDF_RelocationTable::Dump	(	const bool	dumpLabels,
		const bool	dumpAttributes,
		const bool	dumpTransients,
		Standard_OStream &	anOS ) const

Dumps the relocation table.

◆ HasRelocation() [1/3]

bool TDF_RelocationTable::HasRelocation	(	const occ::handle< TDF_Attribute > &	aSourceAttribute,
		occ::handle< TDF_Attribute > &	aTargetAttribute ) const

Finds the relocation value of <aSourceAttribute> and returns it into <aTargetAttribute>.

(See above SelfRelocate method for more explanation about the method behavior)

◆ HasRelocation() [2/3]

template<class T>

bool TDF_RelocationTable::HasRelocation	(	const occ::handle< TDF_Attribute > &	theSource,
		occ::handle< T > &	theTarget ) const

inline

Safe variant for arbitrary type of argument.

◆ HasRelocation() [3/3]

bool TDF_RelocationTable::HasRelocation	(	const TDF_Label &	aSourceLabel,
		TDF_Label &	aTargetLabel ) const

Finds the relocation value of <aSourceLabel> and returns it into <aTargetLabel>.

(See above SelfRelocate method for more explanation about the method behavior)

◆ HasTransientRelocation()

bool TDF_RelocationTable::HasTransientRelocation	(	const occ::handle< Standard_Transient > &	aSourceTransient,
		occ::handle< Standard_Transient > &	aTargetTransient ) const

Finds the relocation value of <aSourceTransient> and returns it into <aTargetTransient>.

(See above SelfRelocate method for more explanation about the method behavior)

◆ LabelTable()

NCollection_DataMap< TDF_Label, TDF_Label > & TDF_RelocationTable::LabelTable ( )

Returns <myLabelTable> to be used or updated.

◆ SelfRelocate() [1/2]

bool TDF_RelocationTable::SelfRelocate ( ) const

Returns <mySelfRelocate>.

◆ SelfRelocate() [2/2]

void TDF_RelocationTable::SelfRelocate ( const bool selfRelocate )

Sets <mySelfRelocate> to <selfRelocate>.

This flag affects the HasRelocation method behavior like this:

<mySelfRelocate> == False:

If no relocation object is found in the map, a null object is returned

<mySelfRelocate> == True:

If no relocation object is found in the map, the method assumes the source object is relocation value; so the source object is returned as target object.

◆ SetRelocation() [1/2]

void TDF_RelocationTable::SetRelocation	(	const occ::handle< TDF_Attribute > &	aSourceAttribute,
		const occ::handle< TDF_Attribute > &	aTargetAttribute )

Sets the relocation value of <aSourceAttribute> to <aTargetAttribute>.

◆ SetRelocation() [2/2]

void TDF_RelocationTable::SetRelocation	(	const TDF_Label &	aSourceLabel,
		const TDF_Label &	aTargetLabel )

Sets the relocation value of <aSourceLabel> to <aTargetLabel>.

◆ SetTransientRelocation()

void TDF_RelocationTable::SetTransientRelocation	(	const occ::handle< Standard_Transient > &	aSourceTransient,
		const occ::handle< Standard_Transient > &	aTargetTransient )

Sets the relocation value of <aSourceTransient> to <aTargetTransient>.

◆ TargetAttributeMap()

void TDF_RelocationTable::TargetAttributeMap ( NCollection_Map< occ::handle< TDF_Attribute > > & anAttributeMap ) const

Fills <anAttributeMap> with target relocation attributes. <anAttributeMap> is not cleared before use.

◆ TargetLabelMap()

void TDF_RelocationTable::TargetLabelMap ( NCollection_Map< TDF_Label > & aLabelMap ) const

Fills <aLabelMap> with target relocation labels. <aLabelMap> is not cleared before use.

◆ TransientTable()

NCollection_IndexedDataMap< occ::handle< Standard_Transient >, occ::handle< Standard_Transient > > & TDF_RelocationTable::TransientTable ( )

Returns <myTransientTable> to be used or updated.
