Examples with CacheInterceptor org.apache.ignite.cache.CacheInterceptor used on opensource projects

Example 1 with CacheInterceptor

use of org.apache.ignite.cache.CacheInterceptor in project ignite by apache.

the class IgniteTxStateImpl method hasInterceptor.

/**
 * {@inheritDoc}
 */
@Override
public boolean hasInterceptor(GridCacheSharedContext cctx) {
    for (int i = 0; i < activeCacheIds.size(); i++) {
        int cacheId = activeCacheIds.get(i);
        CacheInterceptor interceptor = cctx.cacheContext(cacheId).config().getInterceptor();
        if (interceptor != null)
            return true;
    }
    return false;
}

Example 2 with CacheInterceptor

use of org.apache.ignite.cache.CacheInterceptor in project ignite by apache.

the class GridCacheInterceptorAbstractSelfTest method testCancelUpdate.

/**
 * @param key Key.
 * @param op Operation type.
 * @throws Exception If failed.
 */
private void testCancelUpdate(String key, Operation op) throws Exception {
    // Interceptor returns null to disabled update.
    CacheInterceptor retInterceptor = new NullPutInterceptor();
    interceptor.retInterceptor = retInterceptor;
    // Execute update when value is null, it should not change cache value.
    log.info("Update 1 " + op);
    update(0, op, key, 1, null);
    checkCacheValue(key, null);
    // Check values passed to interceptor.
    assertEquals(1, interceptor.beforePutMap.size());
    IgniteBiTuple t = interceptor.beforePutMap.get(key);
    assertEquals(null, t.get1());
    assertEquals(1, t.get2());
    // Disable interceptor and update cache.
    interceptor.reset();
    interceptor.disabled = true;
    clearCaches();
    jcache(0).put(key, 1);
    checkCacheValue(key, 1);
    // Execute update when value is not null, it should not change cache value.
    interceptor.disabled = false;
    interceptor.retInterceptor = retInterceptor;
    log.info("Update 2 " + op);
    update(0, op, key, 2, 1);
    checkCacheValue(key, 1);
    // Check values passed to interceptor.
    assertEquals(1, interceptor.beforePutMap.size());
    t = interceptor.beforePutMap.get(key);
    assertEquals(1, t.get1());
    assertEquals(2, t.get2());
}

/**
 * @param key Key.
 * @param op Operation type.
 * @throws Exception If failed.
 */
private void testModifyUpdate(String key, Operation op) throws Exception {
    // Interceptor returns incremented new value.
    CacheInterceptor retInterceptor = new PutIncrementInterceptor();

    interceptor.retInterceptor = retInterceptor;
    log.info("Update 1 " + op);
    update(0, op, key, 1, null);
