OCM:Supporting nested properties for the FilterImpl

[Boni Gopalan (BioImagene)]

The Filter is a nifty interface that allows hassle free construction of
JCR query strings through a Criterion() like methods.  The default
implementation does a remarkably accurate job of building queries that
are one level deep.  It would be great if the queries can be any level
deep so that one can fetch back any specific 'Object' representation of
a node or a property.

 

Eg.

 

Foo{

String id;           

List<Bar> myBar;

}

 

Bar{

            String id;

            String name;

}

 

Filter(Foo.class); [Not exactly but you get the idea!]

Filter.addEqualsTo("myBar[].name"," C&A's Pub Pub");

 

Ocm.getObjects(Filter) , fetches all the Foos with a nested property
name="C&A's Pub"

 

Any thoughts?  Is it possible with the current API?, 

 

Thanks

Boni
