virtual void	MarkAggregateComponentStatusAsNotCurrent () const
	Call whenever a component status setting is modifed by directly changing it on a component in a way that will result in any saved information about the parent object's aggretate component status becoming invalid. More...

virtual void	MemoryRelocate ()
	The MemoryRelocate() function is called when an object's location in memory is changed. For example, if an object resides in a chunk of memory that is grown by calling a realloc that has to allocate a new chunk and copy the contents of the old chunk to the new chunk, then the location of the object's memory changes. In practice this happens when classes derived from ON_Object are stored in dynamic arrays, like the default implementation of ON_ObjectArray<>'s that use realloc to grow the dynamic array. More...

Tests an object to see if its data members are correctly initialized.

Parameters

text_log	[in] if the object is not valid and text_log is not nullptr, then a brief englis description of the reason the object is not valid is appened to the log. The information appended to text_log is suitable for

overridevirtual

Low level archive writing tool used by ON_BinaryArchive::WriteObject().

Parameters

binary_archive archive to write to

Returns: Returns true if the write is successful.

Use ON_BinaryArchive::WriteObject() to write objects. This Write() function should just write the specific definition of this object. It should not write and any chunk typecode or length information.
