方法详细资料

createDirectory

public boolean createDirectory(DataEntry dataEntry)
                        throws IOException

从接口复制的说明: DataEntryWriter

Creates a directory.

指定者:

createDirectory 在接口中 DataEntryWriter

参数:

dataEntry - the data entry for which the directory is to be created.

返回:

whether the directory has been created.

抛出:

IOException

sameOutputStream

public boolean sameOutputStream(DataEntry dataEntry1,
 DataEntry dataEntry2)
                         throws IOException

从接口复制的说明: DataEntryWriter

Returns whether the two given data entries would result in the same output stream.

指定者:

sameOutputStream 在接口中 DataEntryWriter

参数:

dataEntry1 - the first data entry.

dataEntry2 - the second data entry.

抛出:

IOException

createOutputStream

public OutputStream createOutputStream(DataEntry dataEntry)
                                throws IOException

从接口复制的说明: DataEntryWriter

Creates a new output stream for writing data. The caller is responsible for closing the stream.

指定者:

createOutputStream 在接口中 DataEntryWriter

参数:

dataEntry - the data entry for which the output stream is to be created.

返回:

the output stream. The stream may be null to indicate that the data entry should not be written.

抛出:

IOException

close

public void close()
           throws 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 AutoCloseable

指定者:

close 在接口中 DataEntryWriter

抛出:

IOException

println

public void println(PrintWriter pw,
 String prefix)

从接口复制的说明: DataEntryWriter

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.

protected ZipOutput createZipOutput(OutputStream outputStream,
 byte[] header,
 int uncompressedAlignment,
 boolean useZip64,
 String comment)
                             throws IOException

Creates a zip output with the given header and parameters.
