Class StoredCacheData

java.lang.Object

org.apache.ignite.internal.processors.cache.StoredCacheData

All Implemented Interfaces:

Serializable, CdcCacheEvent

public class StoredCacheData
extends Object
implements Serializable, CdcCacheEvent

Cache data to write to and read from IgnitePageStoreManager. In a nutshell, contains (most importantly) CacheConfiguration and additional information about cache which is not a part of configuration. This class is Serializable and is intended to be read-written with JdkMarshaller in order to be serialization wise agnostic to further additions or removals of fields.

Constructor Detail

StoredCacheData

public StoredCacheData(CacheConfiguration<?,?> ccfg)

Constructor.

Parameters:

ccfg - Cache configuration.

StoredCacheData

public StoredCacheData(StoredCacheData cacheData)

Parameters:

cacheData - Cache data.

Method Detail

config

public void config(CacheConfiguration<?,?> ccfg)

Parameters:

ccfg - Cache configuration.

config

public CacheConfiguration<?,?> config()

Returns:

Cache configuration.

queryEntities

public Collection<QueryEntity> queryEntities()

Description copied from interface: CdcCacheEvent

Returns current state of configured QueryEntity. QueryEntity can be changed by executing DDL on SQL tables. Note, CacheConfiguration.getQueryEntities() returns initial definition of QueryEntity.

Specified by:

queryEntities in interface CdcCacheEvent

Returns:

Query entities.

queryEntities

public void queryEntities(Collection<QueryEntity> qryEntities)

Parameters:

qryEntities - Query entities.

sql

public boolean sql()

Returns:

SQL flag - true if cache was created with CREATE TABLE.

sql

public StoredCacheData sql(boolean sql)

Parameters:

sql - SQL flag - true if cache was created with CREATE TABLE.

groupKeyEncrypted

public GroupKeyEncrypted groupKeyEncrypted()

Returns:

Ciphered encryption key for this cache or cache group. Null if not encrypted.

groupKeyEncrypted

public void groupKeyEncrypted(GroupKeyEncrypted grpKeyEncrypted)

Parameters:

grpKeyEncrypted - Ciphered encryption key for this cache or cache group.

cacheConfigurationEnrichment

public StoredCacheData cacheConfigurationEnrichment(CacheConfigurationEnrichment ccfgEnrichment)

Parameters:

ccfgEnrichment - Configuration enrichment.

cacheConfigurationEnrichment

public CacheConfigurationEnrichment cacheConfigurationEnrichment()

Returns:

Configuration enrichment.

hasOldCacheConfigurationFormat

public boolean hasOldCacheConfigurationFormat()

Returns:

true if configuration enrichment is available.

withSplittedCacheConfig

public StoredCacheData withSplittedCacheConfig(CacheConfigurationSplitter splitter)

Splits the corresponding cache configuration into parts with the given splitter.

Parameters:

splitter - Cache configuration splitter.

toString

public String toString()

Overrides:

toString in class Object

cacheId

public int cacheId()

Specified by:

cacheId in interface CdcCacheEvent

Returns:

Cache ID.

See Also:

CacheView.cacheId()

configuration

public CacheConfiguration<?,?> configuration()

Note, CacheConfiguration.getQueryEntities() value not changed on table schema change. Current table schema can be obtained by CdcCacheEvent.queryEntities().

Specified by:

configuration in interface CdcCacheEvent

Returns:

Initial cache configuration.
