Method Detail

withinTx

public static <T> T withinTx(org.infinispan.AdvancedCache cache,
             Callable<T> c)
                  throws Exception

Call an operation within a transaction. This method guarantees that the right pattern is used to make sure that the transaction is always either committed or rollback.

Type Parameters:

T - type of callable return

Parameters:

cache - instance whose transaction manager to use

c - callable instance to run within a transaction

Returns:

returns whatever the callable returns

Throws:

Exception - if any operation within the transaction fails

withinTx

public static <T> T withinTx(TransactionManager tm,
             Callable<T> c)
                  throws Exception

Call an operation within a transaction. This method guarantees that the right pattern is used to make sure that the transaction is always either committed or rollbacked.

Type Parameters:

T - type of callable return

Parameters:

tm - transaction manager

c - callable instance to run within a transaction

Returns:

returns whatever the callable returns

Throws:

Exception - if any operation within the transaction fails

localCache

public static org.infinispan.AdvancedCache localCache(org.infinispan.AdvancedCache cache)

Transform a given cache into a local cache

Parameters:

cache - to be transformed

Returns:

a cache that operates only in local-mode

ignoreReturnValuesCache

public static org.infinispan.AdvancedCache ignoreReturnValuesCache(org.infinispan.AdvancedCache cache)

Transform a given cache into a cache that ignores return values for operations returning previous values, i.e. BasicCache.put(Object, Object)

Parameters:

cache - to be transformed

Returns:

a cache that ignores return values

ignoreReturnValuesCache

public static org.infinispan.AdvancedCache ignoreReturnValuesCache(org.infinispan.AdvancedCache cache,
                                                   org.infinispan.context.Flag extraFlag)

Transform a given cache into a cache that ignores return values for operations returning previous values, i.e. BasicCache.put(Object, Object), adding an extra flag.

Parameters:

cache - to be transformed

extraFlag - to add to the returned cache

Returns:

a cache that ignores return values

asyncWriteCache

public static org.infinispan.AdvancedCache asyncWriteCache(org.infinispan.AdvancedCache cache,
                                           org.infinispan.context.Flag extraFlag)

Transform a given cache into a cache that writes cache entries without waiting for them to complete, adding an extra flag.

Parameters:

cache - to be transformed

extraFlag - to add to the returned cache

Returns:

a cache that writes asynchronously

failSilentWriteCache

public static org.infinispan.AdvancedCache failSilentWriteCache(org.infinispan.AdvancedCache cache)

Transform a given cache into a cache that fails silently if cache writes fail.

Parameters:

Returns:

a cache that fails silently if cache writes fail

failSilentWriteCache

public static org.infinispan.AdvancedCache failSilentWriteCache(org.infinispan.AdvancedCache cache,
                                                org.infinispan.context.Flag extraFlag)

Transform a given cache into a cache that fails silently if cache writes fail, adding an extra flag.

Parameters:

public static void broadcastEvictAll(org.infinispan.AdvancedCache cache)

Broadcast an evict-all command with the given cache instance.

Parameters:
