[p2-dev] ProvisioningContext

[Scott Lewis <slewis@xxxxxxxxx>]

In several parts of the p2 APIs there is use of a ProvisioningContext 
(e.g. in IDirector, etc).  In looking at a fair amount of actual and p2 
test code in many cases this ProvisioningContext is set to null in the 
usage of the API.     The javadocs frequently say "The provisioning 
context used for finding resources".

What is the intended usage/purpose of ProvisioningContext?  Is it 
required under any circumstances?  If so, which?

Thanks for info,

Scott
