Hi,
I am new on the list, so maybe the topic has already been discussed.
However, I could not find anything in the archives.
I am developing a custom QC plug-in that outputs a large structure
(1025 entries, and each of them is a 2-entries structure). When
running the composition, I observe a huge memory leak (several
megabytes per second). So, I was wondering about how QC manages the
NSDictionary after retrieving it.
Basically, my source code look like:
- in the interface declaration:
@property(assign) NSDictionary* outputStructure;
- in the implementation:
@dynamic outputStructure;
// ...
- (BOOL) execute:(id<QCPlugInContext>)context atTime:
(NSTimeInterval)time withArguments:(NSDictionary*)arguments
{
// ...
id elements[1025];
id keys[1025];
for(unsigned int i=0; i<1025; ++i)
{
elements[i] = [NSDictionary dictionaryWithObjectsAndKeys:
[NSNumber numberWithFloat:someNumber, @"someKey",
[NSNumber numberWithFloat:someOtherNumber],
@"someOtherKey",
nil];
keys[i] = [NSNumber numberWithInt:i];
}
// leak disappears if I uncomment the following line
self. outputStructure = [NSDictionary dictionaryWithObjects:elements
forKeys:keys count:1025];
// ...
}
Thank you for your help,
Ambroise Confetti
