Prs3d_LineAspect Class Reference

A framework for defining how a line will be displayed in a presentation. Aspects of line display include width, color and type of line. The definition set by this class is then passed to the attribute manager Prs3d_Drawer. Any object which requires a value for line aspect as an argument may then be given the attribute manager as a substitute argument in the form of a field such as myDrawer for example. More...

	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.

Detailed Description

A framework for defining how a line will be displayed in a presentation. Aspects of line display include width, color and type of line. The definition set by this class is then passed to the attribute manager Prs3d_Drawer. Any object which requires a value for line aspect as an argument may then be given the attribute manager as a substitute argument in the form of a field such as myDrawer for example.

Prs3d_LineAspect() [1/2]

Prs3d_LineAspect::Prs3d_LineAspect	(	const Quantity_Color &	theColor,
		const Aspect_TypeOfLine	theType,
		const double	theWidth )

Constructs a framework for line aspect defined by.

• the color aColor
• the type of line aType and
• the line thickness aWidth. Type of line refers to whether the line is solid or dotted, for example.
