Constructor Detail

Bzip2FileObject

protected Bzip2FileObject(FileName name,
                          FileObject container,
                          CompressedFileFileSystem fs)

Method Detail

doGetInputStream

protected InputStream doGetInputStream()
                                throws Exception

Description copied from class: AbstractFileObject

Creates an input stream to read the file content from. Is only called if AbstractFileObject.doGetType() returns FileType.FILE.

It is guaranteed that there are no open output streams for this file when this method is called.

The returned stream does not have to be buffered.

Specified by:

doGetInputStream in class AbstractFileObject

Throws:

Exception

wrapInputStream

public static InputStream wrapInputStream(String name,
                                          InputStream is)
                                   throws IOException

Throws:

IOException

doGetOutputStream

protected OutputStream doGetOutputStream(boolean bAppend)
                                  throws Exception

Description copied from class: AbstractFileObject

Creates an output stream to write the file content to. Is only called if:

• AbstractFileObject.doIsWriteable() returns true.
• AbstractFileObject.doGetType() returns FileType.FILE, or AbstractFileObject.doGetType() returns FileType.IMAGINARY, and the file's parent exists and is a folder.

It is guaranteed that there are no open stream (input or output) for this file when this method is called.

The returned stream does not have to be buffered.

This implementation throws an exception.

Overrides:

doGetOutputStream in class AbstractFileObject

Throws:

Exception
