Usage

From source file:org.spring.data.gemfire.cache.PeerCacheFunctionServiceIntegrationTest.java

@Test
public void factorialFunctionComputation() {
    for (int index = 0; index < 10; index++) {
        assertEquals(0, factorials.get(index).intValue());
    }//from ww w.  j a va2s.co  m

    GemfireOnRegionFunctionTemplate functionTemplate = new GemfireOnRegionFunctionTemplate(factorials);
