Constructor Detail

JGroupsBootstrapCacheLoader

public JGroupsBootstrapCacheLoader(boolean asynchronous,
                                   int maximumChunkSize)

Creates a bootstrap cache loader that will work with RMI based distribution

Parameters:

asynchronous - Whether to load asynchronously

Method Detail

load

public void load(net.sf.ehcache.Ehcache cache)
          throws net.sf.ehcache.distribution.RemoteCacheException

Bootstraps the cache from a random CachePeer. Requests are done in chunks estimated at 5MB Serializable size. This balances memory use on each end and network performance.

Specified by:

load in interface net.sf.ehcache.bootstrap.BootstrapCacheLoader

Throws:

net.sf.ehcache.distribution.RemoteCacheException - if anything goes wrong with the remote call

isAsynchronous

public boolean isAsynchronous()

Specified by:

isAsynchronous in interface net.sf.ehcache.bootstrap.BootstrapCacheLoader

Returns:

true if this bootstrap loader is asynchronous

getMaximumChunkSizeBytes

public int getMaximumChunkSizeBytes()

Gets the maximum chunk size

clone

public Object clone()
             throws CloneNotSupportedException

Clones this loader

Specified by:

clone in interface net.sf.ehcache.bootstrap.BootstrapCacheLoader

Overrides:

clone in class Object

Throws:

CloneNotSupportedException
