<V> RBucket<V> getBucket(String name)

Returns transactional object holder instance by name.

Type Parameters:

V - type of value

Parameters:

name - - name of object

Returns:

Bucket object

getBucket

<V> RBucket<V> getBucket(String name,
                         Codec codec)

Returns transactional object holder instance by name using provided codec for object.

Type Parameters:

V - type of value

Parameters:

name - - name of object

codec - - codec for values

Returns:

Bucket object

getBuckets

RBuckets getBuckets()

Returns transactional interface for mass operations with Bucket objects.

Returns:

Buckets

getBuckets

RBuckets getBuckets(Codec codec)

Returns transactional interface for mass operations with Bucket objects using provided codec for object.

Parameters:

codec - - codec for bucket objects

Returns:

Buckets

getMap

<K,V> RMap<K,V> getMap(String name)

Returns transactional map instance by name.

Type Parameters:

K - type of key

V - type of value

Parameters:

name - - name of object

Returns:

getSetCache

<V> RSetCache<V> getSetCache(String name)

Returns transactional set-based cache instance by name. Supports value eviction with a given TTL value.

If eviction is not required then it's better to use regular map getSet(String).

Type Parameters:

V - type of value

Parameters:

name - - name of object

Returns transactional set-based cache instance by name. Supports value eviction with a given TTL value.

If eviction is not required then it's better to use regular map getSet(String, Codec).

Type Parameters:

V - type of value

Parameters:

name - - name of object

codec - - codec for values

Returns:

SetCache object

getMapCache

<K,V> RMapCache<K,V> getMapCache(String name)

Returns transactional map-based cache instance by name. Supports entry eviction with a given MaxIdleTime and TTL settings.

If eviction is not required then it's better to use regular map getMap(String).

Type Parameters:

K - type of key

V - type of value

Parameters:

name - - name of object

Returns:

MapCache object

getMapCache
