      • close

        public void close()
           throws java.io.IOException
        从接口复制的说明: DataEntryWriter
        Finishes writing all data entries.

        Implementations typically create graphs of writers that can split and merge again, possibly even with cycles.

        For splits and merges, implementations need to be idempotent; once closed, subsequent attempts to close a writer have no effect. If needed, the wrapper NonClosingDataEntryWriter can avoid closing a branch prematurely.

        For cycles, implementations must perform any custom behavior, then delegate DataEntryWriter.close() invocations, and only finally clean up. It is possible that delegates call DataEntryWriter.createOutputStream(DataEntry) while DataEntryWriter.close() is in progress.

        指定者:
        close 在接口中 java.lang.AutoCloseable
        指定者:
        close 在接口中 DataEntryWriter
        抛出:
        java.io.IOException

        Prints out the structure of the data entry writer.
        指定者:
        println 在接口中 DataEntryWriter
        参数:
        pw - the print stream to which the structure should be printed.
        prefix - a prefix for every printed line.
