OQL for finding new objects only in heap dumps?

Does anyone know the OQL syntax for finding new objects only in a heap output? I can't find good documentation on OQL options, sun even has an example of new-only output without sample syntax of the query that generated it.What I've done is

• Created a set of heaps with jhat
• Served them up with jmap -baseline, which marks objects not in both heaps as "new".
• browse jhat
• scra开发者_StackOverflow社区tch head

Eclipse memory analyzer is THE tool when it comes to interpreting results of a heap dump. See Why doesn't the -baseline option of jhat work?

At least this page has some examples: jstack-jhat-Object-Query-Language-OQL.html
