LIFESPAN

MAX_IDLE

public static final AttributeDefinition<java.lang.Long> MAX_IDLE

REAPER_ENABLED

public static final AttributeDefinition<java.lang.Boolean> REAPER_ENABLED

WAKEUP_INTERVAL

public static final AttributeDefinition<java.lang.Long> WAKEUP_INTERVAL

ELEMENT_DEFINITION

Method Detail

getElementDefinition

public ElementDefinition getElementDefinition()

Specified by:

getElementDefinition in interface BaseConfigurationInfo

Returns:

the ElementDefinition of the configuration.

lifespan

public long lifespan()

Maximum lifespan of a cache entry, after which the entry is expired cluster-wide, in milliseconds. -1 means the entries never expire. Note that this can be overridden on a per-entry basis by using the Cache API.

maxIdle

public long maxIdle()

Maximum idle time a cache entry will be maintained in the cache, in milliseconds. If the idle time is exceeded, the entry will be expired cluster-wide. -1 means the entries never expire. Note that this can be overridden on a per-entry basis by using the Cache API.

reaperEnabled

public boolean reaperEnabled()

Determines whether the background reaper thread is enabled to test entries for expiration. Regardless of whether a reaper is used, entries are tested for expiration lazily when they are touched.

wakeUpInterval

public long wakeUpInterval()

Interval (in milliseconds) between subsequent runs to purge expired entries from memory and any cache stores. If you wish to disable the periodic eviction process altogether, set wakeupInterval to -1.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

attributes

public AttributeSet attributes()

Specified by:

attributes in interface BaseConfigurationInfo

Returns:

the AttributeSet declared by the configuration.
