Method Detail

utilityCache

<K extends GridCacheUtilityKey,V> IgniteInternalCache<K,V> utilityCache()

Gets utility cache.

Returns:

Utility cache.

cachex

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

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

Type Parameters:

K - Key type.

V - Value type.

Returns:

Default cache instance.

cachesx

Collection<IgniteInternalCache<?,?>> cachesx(@Nullable
                                           IgnitePredicate<? super IgniteInternalCache<?,?>>... 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 Ignite events.

Parameters:

types - Event types.

Returns:

Whether all events are recordable.

Throws:

IllegalArgumentException - If types contains user event type.

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.

igfsx

@Nullable
IgniteFileSystem igfsx(@Nullable
                              String name)

Get IGFS instance returning null if it doesn't exist.

Parameters:

name - IGFS name.

Returns:

IGFS.

hadoop

Hadoop hadoop()

Get Hadoop facade.

Returns:

Hadoop.

cluster

IgniteClusterEx cluster()

Gets an instance of IgniteCluster interface.

Specified by:

cluster in interface Ignite

Returns:

Instance of IgniteCluster interface.

latestVersion

@Nullable
String latestVersion()

Get latest version in string form.

Returns:

Latest version.

localNode

ClusterNode localNode()

Gets local grid node.

Returns:

Local grid node.

context

GridKernalContext context()

Internal context.

Returns:

Kernal context.
