Deprecated. Use Bzip2FileObject(AbstractFileName, FileObject, Bzip2FileSystem) instead.

Deprecated since 2.1.

fs - My file system.

Bzip2FileObject

protected Bzip2FileObject(AbstractFileName name,
                          FileObject container,
                          Bzip2FileSystem fs)

Method Detail

doGetInputStream

protected InputStream doGetInputStream(int bufferSize)
                                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.

Overrides:

doGetInputStream in class AbstractFileObject<Bzip2FileSystem>

Parameters:

bufferSize - Buffer size hint.

Returns:

An InputStream to read the file content.

Throws:

Exception - if an error occurs.

wrapInputStream

public static InputStream wrapInputStream(String name,
                                          InputStream inputStream)
                                   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<Bzip2FileSystem>

Parameters:

bAppend - true if the file should be appended to, false if it should be overwritten.

Returns:

An OutputStream to write to the file.

Throws:

Exception - if an error occurs.
