[eclipselink-users] Tree retrieval using eclipselink

[harshavardhan786 <harshavardhan786@xxxxxxxxx>]

Hi,

We have a model like below:

A:B = 1:N ( A has 'N'   B's  ) 
B:C = 1:N
C:B = 1:N
B:D = 1:N

All above are unidirectional relationships.


Now there is tree/graph of objects populated . 
We have enitity id of A. 

Can I get the whole tree/graph for which A is the root in 1 eclipselink/JPA
call ?

Currently we are traversing the whole tree, which is taking more memory .
Are there any ways to acheive the same traversal using memory-cheap
eclipselink/JPA calls ?

Regards,
Harsha
