How to load the latest version of asm&prt files in Java toolkit,without close the opened assembly

Question

Creo parametric 7.0.0.0 No windchillJava toolkitUser case:1. Creo window 1: opened assembly in creo like this:top.asm.1|--------sub1.asm.1               |--------part.prt.12.Creo window 2: opened  assembly in creo like this:sub1.asm.1               |--------part.prt.13.Creo window 3: opened part in creo like this:part.prt.13.Put the latest version files(sub1.asm.2 part.prt.2) into the file directory;Question:1.Which API can load the latest or specified file version without close the window 1,2,3;2.Do not close all the files and reload ,because the feeling is not good;3.The best way I want :Load only the necessary new version files.Thanks!

I think you will need to explain better what Creo window 1, 2 3 means: Are these 3 windows of the SAME Creo session or you are talking about 3 different Creo sessions on the same workstation?

If everything is running in the same Creo session then once you update a model in one window all the changes are immediately visible in all other windows. For a J-Link or toolkit application it has no relevance if the model is displayed in any window or not..

If running multiple Creo sessions at the same time, things are getting more complicated. One way to do it is to suppress the component that was changed and all the dependent children's, perform an "Erase not displayed" command and resume all components previously suppressed. This will force the system to read the latest version from disk. In large assemblies, with multiple levels of sub-assemblies this kind of procedure can get really difficult to implement.

If you load a file into session you load a string name and an integer type. This combination must be unique in session.

If you omit on open the increment, you will open the file with the highest increment.
specify the increment, will open exact this one
After loading, only the run time ID of the file is important
The model name is used for some relation or on save after loading
the given path is only used on save
open a file where name and type already exist will return an error without loading the file, a different path is ignored during this check
erase a name and type in session, can be done, if this one has no parent
On save the model incr is modified by incr to the highest incr on disc plus 1
Replace a model in session is reserved to PTC as far I knew 😞
Analyse of Parent Cild relations is supported
Write something like this on an iPad is painful 😣

Some simplified tables

If Model Type prt is 1, asm is 2 and drw is 3

Parent 0 is your session at all

Load C:/Models/box.prt.5

Run Time ID	Parent ID	Model Name wchar	Model Type int	Model Path wchar	Model Incr
1	0	BOX	1	C:/Models	5

loading the drawing x342.drw.8 of box.prt may result in

1	2	BOX	1	C:/Models	5
2	0	X342	3	C:/Drawings	8

Now open the assembly mymach.asm.7 where box.prt is a member

1	2	BOX	1	C:/Models	5
2	0	X342	3	C:/Drawings	8
3	0	MYMACH	2	C:/AssyType1	7
1	3	BOX	1	NULL	NULL

Each Window has an ID but no relevance for loading, you can’t have the same model displayed twice.
