Class AbstractTimingStore

java.lang.Object

org.forgerock.openam.shared.monitoring.AbstractTimingStore

public abstract class AbstractTimingStore
extends Object

An abstract store for holding a set of TimingEntrys. The maximum size of the store is set on creation. The store internally uses a synchronizedList, which verifies the size of the collection isn't greater than the maximum upon insertion, and removes the oldest entry if it is. Read operations are not synchronized.

Constructor Detail

AbstractTimingStore

public AbstractTimingStore(int maxEntries)

Constructs a new AbstractTimingStore instance.

Parameters:

maxEntries - The maximum number of entries.

Method Detail

getDurationAverage

public long getDurationAverage()

Getter for the average length of time events recorded in the duration store have taken.

Returns:

a long representation of the average length of time in ms.

getSlowestEvaluation

public String getSlowestEvaluation()

Returns a string representation of the slowest performing policy evaluation. If no policy evaluations have yet been run, this will return the empty String.

Returns:

representation of the slowest performing policy evaluation.

getSlowestEvaluationDuration

public long getSlowestEvaluationDuration()

Returns the long representation of the slowest performing policy evaluation. If no policy evaluations have yet been run, this will return 0.

Returns:

duration of the slowest performing policy evaluation in ms.

getMaxEntries

public int getMaxEntries()

Returns the maximum entries for this store.

Returns:

the maximum number of entries this timing store will hold before removing the oldest entry
