Re: writing collection of refobjects through xmiwriter

Hi Ronald,

my statement is still valid, write(collection) does not create any hrefs to
objects that are not part of the collection parameter.

To serialize repository content in multiple files and control what is where
written you can use the proposed write(OutputStream, RefPackage[],
XMIReferenceProvider) method. If your XMIReferenceProvider returns xmi id for
every RefObject that you want to write in a file and href for every RefObject
that you do not want to write in the file, then you will achieve the desired
behaviour (this writing method will preserve all links).

In another words, to serialize a MOF repository content in multiple files (let's
say File_1, ..., File_N) means to call write(OutputStream, RefPackage[],
XMIReferenceProvider) method N-times and on each i-th call provide a proper
XMIReferenceProvider returning xmi id's for all RefObjects that you want to
write in File_i.
