(Bugzilla 17330) AudioNode context and upstream/downstream references

State:
CLOSED
Product:
Web Audio API
Raised by:
Philip J├Ągenstedt
Opened on:
2012-05-15
Description:
The AudioNode interface includes a reference to the creating context, but not to the connected inputs and outputs. This seems like an odd choice, since the context will typically be easy to find (there's usually only one) but walking the filter graph is very hard and currently requires building a wrapping implementation.

Suggestion:

Drop context, numberOfInputs and numberOfOutputs. Knowing the number of inputs/outputs is by itself not very useful.

Possibly, we could expose an Array-like object for access to the inputs and outputs, but only if the use cases are strong.

Related notes:

My belief is that it's not *that hard* to keep track of these relationships with quite simple wrapper code. After all, most people don't really care about "walking the graph", and those who know what this means can certainly track this state easily themselves. We can change it if most people think this is the way to go, but I don't recommend it since I think it adds more complexity than is necessary.
