Detailed Description

The per-renderer state of the server-side time range management of ONE share.

Bounded: at most max renderers; when a new one arrives the least recently used is dropped. A state is created only for a valid device id (RendererIdPolicy) and only by create; get and update never create one, so lookups with unknown ids cannot grow the map. The map lives inside the share's target, so it disappears with the share. Thread safe.

Constructor & Destructor Documentation

◆ RendererStateMap()

de.yaacc.share.RendererStateMap.RendererStateMap ( int max )

Exceptions

IllegalArgumentException if max is not positive

Member Function Documentation

◆ create()

synchronized State de.yaacc.share.RendererStateMap.create	(	String	deviceId,
		long	initialTimeMs )

Returns: the existing state, or a new one starting at initialTimeMs (dropping the least recently used if the map is full); null for an invalid id

Referenced by de.yaacc.share.ServerSideSeeking.plan().

Here is the caller graph for this function:

◆ get()

synchronized State de.yaacc.share.RendererStateMap.get ( String deviceId )

Returns: the state, or null if there is none or the id is invalid; never creates one

Referenced by de.yaacc.share.ServerSideSeeking.plan().

Here is the caller graph for this function:

◆ update()

synchronized boolean de.yaacc.share.RendererStateMap.update	(	String	deviceId,
		long	timeMs,
		boolean	paused )

Sets the playback time and pause flag of an EXISTING state.

Returns: false if there is no state for the id (nothing is created)

Member Data Documentation

◆ DEFAULT_MAX

final int de.yaacc.share.RendererStateMap.DEFAULT_MAX = 8

static

Renderers per share.

With at most ShareRegistry#DEFAULT_MAX_ACTIVE shares the whole process holds at most 64 states.
