| 63 | * identifying input targets, are controlled by a separate policy object. |
| 64 | * |
| 65 | * IMPORTANT INVARIANT: |
| 66 | * Because the policy can potentially block or cause re-entrance into the input dispatcher, |
| 67 | * the input dispatcher never calls into the policy while holding its internal locks. |
| 68 | * The implementation is also carefully designed to recover from scenarios such as an |
| 69 | * input channel becoming unregistered while identifying input targets or processing timeouts. |
| 70 | * |
| 71 | * Methods marked 'Locked' must be called with the lock acquired. |
| 72 | * |
| 73 | * Methods marked 'LockedInterruptible' must be called with the lock acquired but |
| 74 | * may during the course of their execution release the lock, call into the policy, and |
| 75 | * then reacquire the lock. The caller is responsible for recovering gracefully. |
| 76 | * |
| 77 | * A 'LockedInterruptible' method may called a 'Locked' method, but NOT vice-versa. |
