Detailed Description

This class has been derived from the original turtlebot robot app manager but now tuned for interactions.

The original is quite messy, and this is not much better, so maybe needs extra refactoring. Also RobotAppsManager claims that it can be executed once, but I modified this to execute arbitrary times. It looks to work, but mechanism is a bit brittle. Apps manager implements the services and topics required to interact with the concert roles manager. Typically to use this class its a three step process:

1) instantiate and provide a general failure handler 2) provide a callback via one of the setupXXXservice methods 3) call the service you want; there's a public method per service 4) wait for service response.

Essentially you are creating a node when creating an instance, and rosjava isolates each service/topic to each 'node'.

void com.github.rosjava.android_remocons.common_tools.rocon.InteractionsManager.finalize ( ) throws Throwable [inline, protected]

void com.github.rosjava.android_remocons.common_tools.rocon.InteractionsManager.getAppInfo	(	final MasterId	masterId,
		final int	hash
	)		`[inline]`

This is called from the headless launcher where the only thing it knows is the master id (for connection purposes and the hash stored in an nfc tag (or other). We need to save this hash for later service calls.

Parameters:

masterId
hash

void com.github.rosjava.android_remocons.common_tools.rocon.InteractionsManager.init ( String interactionsNamespace ) [inline]

This is done outside of the constructor to save it from having to be continually reinstantiated in the rocon remocons. That does mean it requires some black magic, i.e. construction -> init & setupXYZ -> execute

Parameters:

interactionsNamespace
