Detailed Description

Manages all filtering on the SPOT.

Multiple Filters can be active at a time. The purpose of this thread is to apply all active filters to a given acceleration sample, remove an sample that a filter has deemed unnecessary and hands the resulting, presumably smaller, list of samples to the ConnectionManager which will then send these samples to the host.

Constructor & Destructor Documentation

FilterManager ( final FrogSpot frog )

Creates the FilterManager with a permanent reference back to the FrogSpot for quick access to its facilities.

Parameters:

frog

reference to the FrogSpot object

Member Function Documentation

void addFilter	(	byte	index,
		String	param
	)

Adds a new instance of a Filter to the list of active filters.

A new filter is added by its index on the array of availFilters and a given parameter String to dictate the Filter's behavior.

Parameters:

	index	position of this filter in the availFilters array
	param	a comma separated string of options for the Filter

Here is the call graph for this function:

void giveGesture ( Queue gesture )

Used by the AccelManager to add a new set of accelerations to the FilterManager's job queue.

The AccelManager hands this queue over before the user is even done with the gesture so processing can take place as the gesture is being made.

Parameters:

gesture

the gesture (currently in progress) to be filtered

Here is the caller graph for this function:

void kill ( )

Attempt to unconditionally stop all threads and release all resources.

Implements Killable.

Here is the caller graph for this function:

void removeFilters ( )

Clears all active filters in this FilterManager.

This is used to wipe the slate clean so that new filters can be used instead.

void run ( )

Constantly loops through a job queue of acceleration data applying all active filters.

Here is the call graph for this function:

Member Data Documentation

final Class [] availFilters [static]

Initial value:

   {
      DirectorialEquivalenceFilter.class,
      IdleStateFilter.class
   }

List of filters that can be instantiated and used by the FilterManager.

If future Filters are written, they should be added to this list. The index of a given class is used by MSG_ADD_FILTER in the ConnectionManager to add additional filters to the FilterManager's activeFilter list.
