Inheritance diagram for RWObj_ObjMaterialMap:

Public Member Functions
	RWObj_ObjMaterialMap (const TCollection_AsciiString &theFile)
	Main constructor.
	~RWObj_ObjMaterialMap () override
	Destructor, will emit error message if file was not closed.
TCollection_AsciiString	AddMaterial (const XCAFPrs_Style &theStyle) override
	Add material.
void	DefineMaterial (const XCAFPrs_Style &theStyle, const TCollection_AsciiString &theKey, const TCollection_AsciiString &theName) override
	Virtual method actually defining the material (e.g. export to the file).
Public Member Functions inherited from RWMesh_MaterialMap
	RWMesh_MaterialMap (const TCollection_AsciiString &theFile)
	Main constructor.
	~RWMesh_MaterialMap () override
	Destructor.
const XCAFPrs_Style &	DefaultStyle () const
	Return default material definition to be used for nodes with only color defined.
void	SetDefaultStyle (const XCAFPrs_Style &theStyle)
	Set default material definition to be used for nodes with only color defined.
TCollection_AsciiString	FindMaterial (const XCAFPrs_Style &theStyle) const
	Find already registered material.
virtual bool	CreateTextureFolder ()
	Create texture folder "modelName/textures"; for example: MODEL: Path/ModelName.gltf IMAGES: Path/ModelName/textures/ Warning! Output folder is NOT cleared.
virtual bool	CopyTexture (TCollection_AsciiString &theResTexture, const occ::handle< Image_Texture > &theTexture, const TCollection_AsciiString &theKey)
	Copy and rename texture file to the new location.
bool	IsFailed () const
	Return failed flag.
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.
