示例1: fromCollection
import org.apache.flink.api.java.io.IteratorInputFormat; //导入依赖的package包/类
/**
* Creates a DataSet from the given iterator. Because the iterator will remain unmodified until
* the actual execution happens, the type of data returned by the iterator must be given
* explicitly in the form of the type information. This method is useful for cases where the type
* is generic. In that case, the type class (as given in {@link #fromCollection(Iterator, Class)}
* does not supply all type information.
* <p>
* The iterator must be serializable (as defined in {@link java.io.Serializable}), because the
* framework may move it to a remote environment, if needed.
* <p>
* Note that this operation will result in a non-parallel data source, i.e. a data source with
* a degree of parallelism of one.
*
* @param data The collection of elements to create the data set from.
* @param type The TypeInformation for the produced data set.
* @return A DataSet representing the elements in the iterator.
*
* @see #fromCollection(Iterator, Class)
