Public Member Functions
virtual const char *	GetMessageKey () const
	Return a C string to be used as a key for generating text user messages describing this alert. The messages are generated with help of Message_Msg class, in Message_Report::Dump(). Base implementation returns dynamic type name of the instance.
virtual bool	SupportsMerge () const
	Return true if this type of alert can be merged with other of the same type to avoid duplication. Basis implementation returns true.
virtual bool	Merge (const occ::handle< Message_Alert > &theTarget)
	If possible, merge data contained in this alert to theTarget.
virtual void	DumpJson (Standard_OStream &theOStream, int theDepth=-1) const
	Dumps the content of me into the stream.
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
typedef void	base_type
	Returns a type descriptor about this object.
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.

Detailed Description

Base class of the hierarchy of classes describing various situations occurring during execution of some algorithm or procedure.

Alert should provide unique text identifier that can be used to distinguish particular type of alerts, e.g. to get text message string describing it. See method GetMessageKey(); by default, dynamic type name is used.

Alert can contain some data. To avoid duplication of data, new alert can be merged with another one of the same type. Method SupportsMerge() should return true if merge is supported; method Merge() should do the merge if possible and return true in that case and false otherwise.

◆ DumpJson()

virtual void Message_Alert::DumpJson	(	Standard_OStream &	theOStream,
		int	theDepth = -1 ) const

virtual

Dumps the content of me into the stream.

Reimplemented in Message_AlertExtended.

◆ GetMessageKey()

virtual const char * Message_Alert::GetMessageKey ( ) const

virtual

Return a C string to be used as a key for generating text user messages describing this alert. The messages are generated with help of Message_Msg class, in Message_Report::Dump(). Base implementation returns dynamic type name of the instance.

Reimplemented in Message_AlertExtended.
