      • createDirectory

        public boolean createDirectory​(DataEntry dataEntry)
                        throws java.io.IOException
        Description copied from interface: DataEntryWriter
        Creates a directory.
        Specified by:
        createDirectory in interface DataEntryWriter
        Parameters:
        dataEntry - the data entry for which the directory is to be created.
        Returns:
        whether the directory has been created.
        Throws:
        java.io.IOException

      • sameOutputStream

        public boolean sameOutputStream​(DataEntry dataEntry1,
                                DataEntry dataEntry2)
                         throws java.io.IOException
        Description copied from interface: DataEntryWriter
        Returns whether the two given data entries would result in the same output stream.
        Specified by:
        sameOutputStream in interface DataEntryWriter
        Parameters:
        dataEntry1 - the first data entry.
        dataEntry2 - the second data entry.
        Throws:
        java.io.IOException

      • createOutputStream

        public java.io.OutputStream createOutputStream​(DataEntry dataEntry)
                                        throws java.io.IOException
        Description copied from interface: DataEntryWriter
        Creates a new output stream for writing data. The caller is responsible for closing the stream.
        Specified by:
        createOutputStream in interface DataEntryWriter
        Parameters:
        dataEntry - the data entry for which the output stream is to be created.
        Returns:
        the output stream. The stream may be null to indicate that the data entry should not be written.
        Throws:
        java.io.IOException

      • close

        public void close()
           throws java.io.IOException
        Description copied from interface: 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.

        Specified by:
        close in interface java.lang.AutoCloseable
        Specified by:
        close in interface DataEntryWriter
        Throws:
        java.io.IOException

      • println

        public void println​(java.io.PrintWriter pw,
                    java.lang.String prefix)
        Description copied from interface: DataEntryWriter
        Prints out the structure of the data entry writer.
        Specified by:
        println in interface DataEntryWriter
        Parameters:
        pw - the print stream to which the structure should be printed.
        prefix - a prefix for every printed line.
