WTCalendarCache

public WTCalendarCache()
                throws RemoteException

Contruct a new calendar cache.

Method Detail

overflow

protected void overflow(Object key,
                        Object value)

overide super.overflow to caputure overflow occurences and clean up supporting caches

Overrides:

overflow in class CacheManager

remove

protected void remove(long pid)

remove

protected void remove(StartEndKey key)

removeEntry

protected void removeEntry(Object target)

Simply clear local cache when signalled. It will be repopulated on subsequent requests

Overrides:

removeEntry in class CacheManager

Parameters:

target - the key object (null = clear entire cache)

reportCacheStats

private void reportCacheStats()

get

public Object get(StartEndKey key)

Cover method for CacheManager get that tests for a set of keys refering to the same object

put

public void put(StartEndKey key,
                Object value)

reset

public void reset()
           throws RemoteException

Description copied from class: CacheManager

Reset local cache after master reconnect. Called after recovery from communication failure when a connection to a new master has been established. The current cache contents are cleared and the local cache is registered as a slave of the new master.

NOTE: This may be called as a result of calling other cache updating operations since that is when the disconnect and reconnect may take place. When this happens, this method is called before the other methods return.

Supported API: true

Overrides:

reset in class CacheManager

Throws:

RemoteException

getDefaultSize

public int getDefaultSize()

Description copied from class: CacheManager

Get desired size of this cache. This method attemps to find a size property called wt.cache.size.CacheName where cacheName is the name of this cache. Subclasses can override this method to control cache size in some other way. If no property is found, the default size is 100.

Supported API: true

Overrides:

getDefaultSize in class CacheManager
