Field Detail

OBLIVION_THRESHOLD

public static final int OBLIVION_THRESHOLD

The number of last entries stored for each context in getUseCount(StatisticsInfo). If more entries are used over time, use count will be 0 for the most ancient entries.

Constant Field Values

RECENCY_OBLIVION_THRESHOLD

public static final int RECENCY_OBLIVION_THRESHOLD

The number of last entries stored for each context in getLastUseRecency(StatisticsInfo). If more entries are used over time, recency will be Integer.MAX_INT for the most ancient entries.

Method Detail

serialize

public static <T,Loc> StatisticsInfo serialize(Key<? extends Statistician<T,Loc>> key,
                                               T element,
                                               Loc location)

getInstance

public static StatisticsManager getInstance()

getUseCount

public abstract int getUseCount(StatisticsInfo info)

Returns:

how many times info.getValue() was used among all recently registered entries with the same info.getContext().

See Also:

incUseCount(StatisticsInfo), OBLIVION_THRESHOLD

getLastUseRecency

public abstract int getLastUseRecency(StatisticsInfo info)

Returns:

the position of info.getValue() in all recently registered entries with the same info.getContext(). 0 if it it's the most recent entry, Integer.MAX_INT if it was never used or was used too long ago (more than RECENCY_OBLIVION_THRESHOLD since other entries with the same context have been registered with incUseCount(StatisticsInfo)).

incUseCount

public abstract void incUseCount(StatisticsInfo info)

Registers a usage of an entry represented by info parameter. This will affect subsequent getUseCount(StatisticsInfo) and getLastUseRecency(StatisticsInfo) results.

getUseCount

public <T,Loc> int getUseCount(Key<? extends Statistician<T,Loc>> key,
                               T element,
                               Loc location)

incUseCount

public <T,Loc> void incUseCount(Key<? extends Statistician<T,Loc>> key,
                                T element,
                                Loc location)

getAllValues

public abstract StatisticsInfo[] getAllValues(java.lang.String context)

Returns:

infos by this context ordered by usage time: recent first
