levels - recursion levels limit, -1 means no limit

maxResources - maximum number of resources to collect, ignored if levels == 1

resource - the root resource to traverse

Method Detail

collectResources

public int collectResources()
                     throws org.apache.sling.api.request.RecursionTooDeepException

Recursive descent from startResource, collecting JSONObjects into startObject. Throws a RecursionTooDeepException if the maximum number of nodes is reached on a "deep" traversal (where "deep" === level greater than 1).

Returns:

-1 if everything went fine, a positive value when the resource has more child nodes then allowed.

Throws:

org.apache.sling.api.request.RecursionTooDeepException
