Redesign NodeInfo.getReferences()
---------------------------------
Key: JCR-1418
URL: https://issues.apache.org/jira/browse/JCR-1418
Project: Jackrabbit
Issue Type: Improvement
Components: jackrabbit-spi
Affects Versions: 1.4
Reporter: Marcel Reutegger
Priority: Minor
The method returns an array of PropertyIds. When there are lots of references
this may become an problem. As with any other return value that potentially is
large we should return an iterator.
I suggest to redesign the handling of references in line with recent
discussions how child infos are handled.
- A NodeInfo implementation must either return the complete list of PropertyIds
or null if it does not want to return the PropertyIds at that time.
- Introduce a new method: Iterator<PropertyId>
RepositoryService.getReferences(SessionInfo, NodeId)
This has the following advantages:
- loading of references can be delayed until it is really needed
- large collections of references can be streamed through the SPI
