Chris Hubick updated CMIS-110:
------------------------------
Attachment: chemistry_parent_entity.patch
The attached patch tackles several issues with current Chemistry.
First, EntryReader needs some way to return not just the Entry being processed,
but also any nested children. This core of this patch is a modification to the
EntryReader methods to return a List of results instead of a single one.
That way, when AbstractObjectReader encounters a nested Entry, it can call
itself to process it recursively, and add those entries to it's own result list.
The second problem, is that when calling the Folder Tree and Descendant
methods, all the APPObjectEntry's are grouped into a single result list, losing
the original hierarchical structure. This isn't so much of a problem for
folders, because the parentId property can be used to infer that structure, but
documents don't use parentId. I thought about introducing a fake "parentId"
property, but I don't think that's a good idea (complications saving, etc), so
this patch tackles this by introducing an APPObjectEntry 'parent' member. This
enables a method like:
public static final boolean isChild(final APPObjectEntry folder, final
APPObjectEntry object) {
if (object.getParent().getId().equals(folder.getId())) return true;
return folder.getId().equals(object.getValue(Property.PARENT_ID));
}
Which will work when the 'object' arg is a folder or a document.

> Hi.
> When using the CMIS Folder Tree and Descendant functions with Alfresco, I get
> back an Atom 'feed' containing 'entry' elements, which have a cmis/restatom
> 'children' element, which then recursively holds further Atom 'entry'
> elements for the child documents of the parent entry. These recursive
> 'entry' elements are currently ignored by Chemistry.
