Integration into Vcs Commit command

Hi, I'm writing my own code inspection plugin.Now,I want to integrate my plugin  before Vcs Commit command.

So the effect should be like:
1) User clicks Commit
2) perform my inspection analysis
3) Commit is performed if it doesn't have bugs.

I know this already in IDEA,but I only care my own inspections.

so my question is,which API I can implement this.
