    when(mock.next()).thenReturn(new Cache.Entry<Object, Object>() {

        @Override
        public Object getKey() {
            return "foo";
        }

        @Override
        public Object getValue() {
            return "bar";
        }

        @Override
        public <T> T unwrap(Class<T> clazz) {
            throw new UnsupportedOperationException("Implement me!");
        }
    });
    when(cache.iterator()).thenReturn(mock);
    final Map<String, String> map = region.toMap();
    assertThat(map.size(), is(1));
    assertThat(map.get("foo"), equalTo("bar"));
}

Example 2 with Cache

the class MemcacheGaeImpl method flush.

@Override
public void flush() {
    try {
        Cache cache = CacheManager.getInstance().getCacheFactory().createCache(Collections.emptyMap());
        cache.clear();
    } catch (CacheException ex) {
        logger.log(Level.SEVERE, "Failed to create cache instance.", ex);
    }
}

Example 3 with Cache

use of javax.cache.Cache in project ignite by apache.

the class CacheUtils method foreach.

/**
     * @param cacheName Cache name.
     * @param fun An operation that accepts a cache entry and processes it.
     * @param keyFilter Cache keys filter.
     * @param <K> Cache key object type.
     * @param <V> Cache value object type.
     */

    bcast(cacheName, () -> {
        Ignite ignite = Ignition.localIgnite();
        IgniteCache<K, V> cache = ignite.getOrCreateCache(cacheName);
        int partsCnt = ignite.affinity(cacheName).partitions();
        // Use affinity in filter for scan query. Otherwise we accept consumer in each node which is wrong.
        Affinity affinity = ignite.affinity(cacheName);
        ClusterNode locNode = ignite.cluster().localNode();
        // Iterate over all partitions. Some of them will be stored on that local node.
        for (int part = 0; part < partsCnt; part++) {
            int p = part;
            // Query returns an empty cursor if this partition is not stored on this node.
            for (Cache.Entry<K, V> entry : cache.query(new ScanQuery<K, V>(part, (k, v) -> affinity.mapPartitionToNode(p) == locNode && (keyFilter == null || keyFilter.apply(k))))) fun.accept(new CacheEntry<>(entry, cache));
        }
    });
}

Example 4 with Cache

use of javax.cache.Cache in project ignite by apache.

the class IgniteDbPutGetAbstractTest method testPutGetLarge.

/**
     * @throws Exception if failed.
     */
public void testPutGetLarge() throws Exception {
    IgniteEx ig = grid(0);
    IgniteCache<Integer, byte[]> cache = ig.cache(DEFAULT_CACHE_NAME);
    final byte[] val = new byte[2048];
    ThreadLocalRandom.current().nextBytes(val);
    cache.put(0, val);
    Assert.assertArrayEquals(val, cache.get(0));
    final IgniteCache<Integer, LargeDbValue> cache1 = ig.cache("large");

        assertEquals(1, entry.getKey().intValue());
        assertEquals(large, entry.getValue());
    }
    cache.remove(0);
    cache1.remove(1);
    assertNull(cache.get(0));
    assertNull(cache1.get(1));
