GetSize
The GetSize method returns the size (number of bytes) of the data in the focus context.
ODULong GetSize ();
return value
The size (in bytes) of the data in the focus context, expressed as an unsigned 32-bit value.

DISCUSSION
If the focus context is the storage unit that created this storage-unit view, this method returns the total size of all properties and values in the storage unit. If the focus context is a property, this method returns the total size of all values in the focused property. If the focus context is a value, this method returns the size of the data stream corresponding to the focused value.
If the focused value is a promise value, the promise is fulfilled before the size of the value is evaluated.

EXCEPTIONS
If the storage-unit cursor for this storage-unit view does not represent a legal focus context for the storage unit that created this storage-unit view, this method throws exceptions raised by the FocusWithCursor method of that storage unit.
