From source file:org.springframework.integration.aggregator.AbstractCorrelatingMessageHandler.java

public AbstractCorrelatingMessageHandler(MessageGroupProcessor processor, MessageGroupStore store,
        CorrelationStrategy correlationStrategy, ReleaseStrategy releaseStrategy) {
    Assert.notNull(processor);//from  w  w  w.  j  a v a  2 s .c  om

    Assert.notNull(store);
