Public Member Functions
	Units_Unit (const Standard_CString aname, const Standard_CString asymbol, const Standard_Real avalue, const Handle< Units_Quantity > &aquantity)
	Creates and returns a unit. <aname> is the name of the unit, <asymbol> is the usual abbreviation of the unit, and <avalue> is the value in relation to the International System of Units.

	Units_Unit (const Standard_CString aname, const Standard_CString asymbol)
	Creates and returns a unit. <aname> is the name of the unit, <asymbol> is the usual abbreviation of the unit.

	Units_Unit (const Standard_CString aname)
	Creates and returns a unit. <aname> is the name of the unit.

TCollection_AsciiString	Name () const
	Returns the name of the unit <thename>

void	Symbol (const Standard_CString asymbol)
	Adds a new symbol <asymbol> attached to <me>.

Standard_Real	Value () const
	Returns the value in relation with the International System of Units.

Handle< Units_Quantity >	Quantity () const
	Returns <thequantity> contained in <me>.

Handle< TColStd_HSequenceOfHAsciiString >	SymbolsSequence () const
	Returns the sequence of symbols <thesymbolssequence>

void	Value (const Standard_Real avalue)
	Sets the value <avalue> to <me>.

void	Quantity (const Handle< Units_Quantity > &aquantity)
	Sets the physical Quantity <aquantity> to <me>.

virtual Handle< Units_Token >	Token () const
	Starting with <me>, returns a new Token object.

Standard_Boolean	IsEqual (const Standard_CString astring) const
	Compares all the symbols linked within <me> with the name of <atoken>, and returns True if there is one symbol equal to the name, False otherwise.

virtual void	Dump (const Standard_Integer ashift, const Standard_Integer alevel) const
	Useful for debugging.

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 ()
	Destructor must be virtual.

virtual const opencascade::handle< Standard_Type > &	DynamicType () const
	Returns a type descriptor about this object.

Standard_Boolean	IsInstance (const opencascade::handle< Standard_Type > &theType) const
	Returns a true value if this is an instance of Type.

Standard_Boolean	IsInstance (const Standard_CString theTypeName) const
	Returns a true value if this is an instance of TypeName.

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.

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.

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.

Standard_Integer	GetRefCount () const noexcept
	Get the reference counter of this object.

void	IncrementRefCounter () noexcept
	Increments the reference counter of this object.

Standard_Integer	DecrementRefCounter () noexcept
	Decrements the reference counter of this object; returns the decremented value.

virtual void	Delete () const
	Memory deallocator for transient classes.

Additional Inherited Members
Public Types inherited from Standard_Transient
typedef void	base_type

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.
