Method Detail

cachex

@Nullable
<K,V> GridCache<K,V> cachex(@Nullable
                                   String name)

Gets the cache instance for the given name if one is configured or null otherwise returning even non-public caches.

Type Parameters:

K - Key type.

V - Value type.

Parameters:

name - Cache name.

Returns:

Cache instance for given name or null if one does not exist.

cachex

@Nullable
<K,V> GridCache<K,V> cachex()

Gets default cache instance if one is configured or null otherwise returning even non-public caches. The GridCacheProjection.name() method on default instance returns null.

Type Parameters:

K - Key type.

V - Value type.

Returns:

Default cache instance.

cachesx

Collection<GridCache<?,?>> cachesx(@Nullable
                                 GridPredicate<? super GridCache<?,?>>... p)

Gets configured cache instance that satisfy all provided predicates including non-public caches. If no predicates provided - all configured caches will be returned.

Parameters:

p - Predicates. If none provided - all configured caches will be returned.

Returns:

Configured cache instances that satisfy all provided predicates.

eventUserRecordable

boolean eventUserRecordable(int type)

Checks if the event type is user-recordable.

Parameters:

type - Event type to check.

Returns:

true if passed event should be recorded, false - otherwise.

allEventsUserRecordable

boolean allEventsUserRecordable(int[] types)

Checks whether all provided events are user-recordable.

Note that this method supports only predefined GridGain events.

Parameters:

types - Event types.

Returns:

Whether all events are recordable.

Throws:

IllegalArgumentException - If types contains user event type.

compatibleVersions

Collection<String> compatibleVersions()

Gets list of compatible versions.

Returns:

Compatible versions.

licenseGracePeriodLeft

long licenseGracePeriodLeft()

Returns:

Grace period left in minutes if bursting or -1 otherwise.

isJmxRemoteEnabled

boolean isJmxRemoteEnabled()

Whether or not remote JMX management is enabled for this node.

Returns:

True if remote JMX management is enabled - false otherwise.

isRestartEnabled

boolean isRestartEnabled()

Whether or not node restart is enabled.

Returns:

True if restart mode is enabled, false otherwise.

isSmtpEnabled

boolean isSmtpEnabled()

Whether or not SMTP is configured.

Returns:

True if SMTP is configured - false otherwise.

sendAdminEmailAsync

GridFuture<Boolean> sendAdminEmailAsync(String subj,
                                      String body,
                                      boolean html)

Schedule sending of given email to all configured admin emails.

drPool

@Nullable
ExecutorService drPool()

Get DR pool.

Returns:

DR pool.
