Missing GstValueList #45

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
There doesn't seem to be any implementation for GstValueList, the attached
patch adds some.

there is a GValueAPI.GValueArray so this patch a bit redundant.. but i added it.
it'd be useful to test wether both Structure's getArray and getValueList are 
working.

Why is it redundant? If I try to call Structure#getArray instead of
Structure#getValueList, I get a NullPointerException:

java.lang.NullPointerException

can you send a small test example?

Maybe there was a misunderstanding here, I didn't mean that there would be a 
problem
with getArray method. As far as I know, getArray should not work in my case, 
because
the value is a value list and not an array (I'm receiving audio level messages 
from a
level element). My point was just that you can't use getArray instead of 
getValueList
(and I didn't understand why the patch is redundant).
