Use this class to create beacon fences.
The fences in this class support detecting nearby beacons that are associated with attachments, which are a triple of namespace, type, and content.
Note: Values that indicate a changing state are momentarily TRUE
for about 5 seconds, then automatically revert to FALSE.
| static AwarenessFence |
found(Collection<BeaconState.TypeFilter>
beaconTypes)
This fence is momentarily
TRUE (about 5 seconds) when a beacon with the specified types is
found.

|
| static AwarenessFence |
lost(Collection<BeaconState.TypeFilter>
beaconTypes)
This fence is momentarily
TRUE (about 5 seconds) when a beacon with the specified types is
lost.

| static AwarenessFence |
near(TypeFilter...
beaconTypes)
This fence evaluates to
TRUE if any of the specified types is found but not lost.
