Class InfinispanUtil

java.lang.Object
  org.modeshape.jcr.InfinispanUtil

public class InfinispanUtil
extends Object

A set of utility methods for Infinispan caches.

Nested Class Summary

static interface	InfinispanUtil.Combiner<T> The interface that defines how the results should be merged
protected static class	InfinispanUtil.GetAllKeys<K,V> A DistributedCallable implementation that returns the set of keys in an Infinispan cache which are stored in memory.
protected static class	InfinispanUtil.GetAllMemoryKeys<K,V> A DistributedCallable implementation that returns the set of keys in an Infinispan cache.
protected static class	InfinispanUtil.KeyMerger<K> Since keys can appear more than one time e.g. multiple owners in a distributed cache, they all must be merged into a Set.
static class	InfinispanUtil.Location
static interface	InfinispanUtil.Sequence<T> A sequence of values.

Method Detail

execute

public static <K,V,T> T execute(org.infinispan.Cache<K,V> cache,
                                InfinispanUtil.Location location,
                                org.infinispan.distexec.DistributedCallable<K,V,T> callable,
                                InfinispanUtil.Combiner<T> combiner)
                 throws InterruptedException,
                        ExecutionException

Utility to run the supplied callable in all the processes where the cache is being run.

Type Parameters:

K - the type of key used in the cache

V - the type of value used in the cache

T - the type of result

Parameters:

cache - the cache

location - the location where the callable should be run; if null, InfinispanUtil.Location.LOCALLY is used

callable - the callable

combiner - the component that can combine multiple results of type T into a single result

Returns:

the result of the operation

Throws:

InterruptedException - if the process is interrupted

ExecutionException - if there is an error while getting executing the operation

getAllKeys

public static <K,V> InfinispanUtil.Sequence<K> getAllKeys(org.infinispan.Cache<K,V> cache)
                                             throws org.infinispan.loaders.CacheLoaderException,
                                                    InterruptedException,
                                                    ExecutionException

Get all of the keys in the cache.

Type Parameters:

K - the type of key

V - the type of value

Parameters:

cache - the cache

Returns:

the sequence that can be used to obtain the keys; never null

Throws:

org.infinispan.loaders.CacheLoaderException - if there is an error within the cache loader

InterruptedException - if the process is interrupted

ExecutionException - if there is an error while getting all keys
