Query duration about gstreamer-java

[GoogleCodeExporter]

I think its a valid request, currently gstreamer-java only exposes some of the 
query functions in the Pipeline class.

While gst_element_query may be called on any element, not all elements have a 
handler query.

"For elements that don't implement a query handler, this function forwards the 
query to a random srcpad or to the peer of a random linked sinkpad of this 
element." [1]

So even if you target a specific element for a query, it might propagate that 
query onward to connected elements. To me this is not well defined behavior 
especially as it still may return false after exhausting its links. Perhaps 
since the pipeline will forward these queries, the function calls exist there.

That is my thought behind why it is in the Pipeline class. :)

However since it really is apart of the GstElementAPI, should it really exist 
in the Element class? There are elements that can handle queries.

Thanks,
Michael

I guess the same applies to some other methods as well, e.g., seeking, for 
which I can't find a counterpart for Bin elements either, only the Pipeline.
