 BRepGraph_CacheKind (const Standard_GUID &theID, const TCollection_AsciiString &theName=TCollection_AsciiString(), const int theNodeKindsMask=0)
 Create a cache kind descriptor.
 
const Standard_GUIDID () const
 Stable public identity.

 Display-only metadata.
 
int NodeKindsMask () const
 Optional node-kind applicability mask.
 
bool SupportsNodeKind (const BRepGraph_NodeId::Kind theKind) const
 True if this cache kind is applicable to the given node kind. Cache kinds with NodeKindsMask() == 0 are treated as unrestricted.
 
- Public Member Functions inherited from Standard_Transient
 Standard_Transient ()
 Empty constructor.
 
 Standard_Transient (const Standard_Transient &)
 Copy constructor – does nothing.
 
Standard_Transientoperator= (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_TransientThis () 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.

Detailed Description

Descriptor of one transient cache family.

A cache kind defines stable public identity for one class of transient, recomputable per-node data such as bounding boxes or UV bounds. Instances are process-global descriptors registered in BRepGraph_CacheKindRegistry and referenced from graphs by dense runtime slots.

Constructor & Destructor Documentation

◆ BRepGraph_CacheKind()

BRepGraph_CacheKind::BRepGraph_CacheKind ( const Standard_GUID & theID,
const TCollection_AsciiString & theName = TCollection_AsciiString(),
const int theNodeKindsMask = 0 )

Create a cache kind descriptor.

Parameters
[in]theIDstable public GUID identity
[in]theNamedisplay-only name
[in]theNodeKindsMaskoptional node-kind applicability mask; 0 means "unspecified / unrestricted"

Member Function Documentation

◆ ID()

const Standard_GUID & BRepGraph_CacheKind::ID ( ) const
inline

Stable public identity.

◆ KindBit()

static int BRepGraph_CacheKind::KindBit ( const BRepGraph_NodeId::Kind theKind)
inlinestatic

Convenience: bitmask bit for a given node kind.

◆ Name()

const TCollection_AsciiString & BRepGraph_CacheKind::Name ( ) const
inline

Display-only metadata.

◆ NodeKindsMask()

int BRepGraph_CacheKind::NodeKindsMask ( ) const
inline

Optional node-kind applicability mask.

◆ SupportsNodeKind()

bool BRepGraph_CacheKind::SupportsNodeKind ( const BRepGraph_NodeId::Kind theKind) const
inline

True if this cache kind is applicable to the given node kind. Cache kinds with NodeKindsMask() == 0 are treated as unrestricted.
