示例1: addAndGet
import com.gigaspaces.client.ChangeSet; //导入依赖的package包/类
/**
* Atomically adds the given value to the current value of an entry's property.
* @param gigaSpace the gigaspace which stores the entry.
* @param idQuery id the query which is used to locate the entry.
* @param path the path to the number property which is being modified.
* @param delta the value to add.
* @param modifiers the change modifiers to use.
* @param timeout time to wait if the entry is locked under a transaction.
* @param timeUnit units for the timeout.
* @return the updated value, null of no matching entry found for the given id query. Therefore you must use the
* primitive wrapper types as the result value (e.g. Integer/Long) otherwise you may get {@link NullPointerException} if no entry was found.
