org.apache.jcs.auxiliary.disk.jdbc.mysql
Class MySQLDiskCache<K extends Serializable,V extends Serializable>

java.lang.Object
  org.apache.jcs.auxiliary.AbstractAuxiliaryCache<K,V>
      org.apache.jcs.auxiliary.AbstractAuxiliaryCacheEventLogging<K,V>
          org.apache.jcs.auxiliary.disk.AbstractDiskCache<K,V>
              org.apache.jcs.auxiliary.disk.jdbc.JDBCDiskCache<K,V>
                  org.apache.jcs.auxiliary.disk.jdbc.mysql.MySQLDiskCache<K,V>

All Implemented Interfaces:: AuxiliaryCache<K,V>, ICache<K,V>, ICacheType

public class MySQLDiskCache<K extends Serializable,V extends Serializable>
extends JDBCDiskCache<K,V>
extends JDBCDiskCache<K,V>

The MySQLDiskCache extends the core JDBCDiskCache.

Although the generic JDBC Disk Cache can be used for MySQL, the MySQL JDBC Disk Cache has additional features, such as table optimization that are particular to MySQL.

Constructor Summary
`MySQLDiskCache(MySQLDiskCacheAttributes attributes, TableState tableState, ICompositeCacheManager compositeCacheManager)` Delegates to the super and makes use of the MySQL specific parameters used for scheduled optimization.

Method Summary
`String`	`constructLikeParameterFromPattern(String pattern)`
`protected int`	`deleteExpired()` Removed the expired.
`protected ICacheElement<K,V>`	`processGet(K key)` This delegates to the generic JDBC disk cache.
`protected Map<K,ICacheElement<K,V>>`	`processGetMatching(String pattern)` This delegates to the generic JDBC disk cache.
`protected void`	`processUpdate(ICacheElement<K,V> element)` This delegates to the generic JDBC disk cache.

Constructor Detail

MySQLDiskCache

public MySQLDiskCache(MySQLDiskCacheAttributes attributes,
                      TableState tableState,
                      ICompositeCacheManager compositeCacheManager)

Delegates to the super and makes use of the MySQL specific parameters used for scheduled optimization.

Parameters:: attributes -; tableState -; compositeCacheManager -

Method Detail

processGet

protected ICacheElement<K,V> processGet(K key)

This delegates to the generic JDBC disk cache. If we are currently optimizing, then this method will balk and return null.

Overrides:: processGet in class JDBCDiskCache<K extends Serializable,V extends Serializable>

Parameters:: key - Key to locate value for.
Returns:: An object matching key, or null.
See Also:: AbstractDiskCache.doGet(java.io.Serializable)

processGetMatching

protected Map<K,ICacheElement<K,V>> processGetMatching(String pattern)
