Method Detail

doDetach

protected void doDetach()
                 throws java.lang.Exception

Deprecated.

Detaches this file object from its file resource.

Overrides:

doDetach in class AbstractFileObject<FS extends HttpFileSystem>

Throws:

java.lang.Exception - if an error occurs.

doGetContentSize

protected long doGetContentSize()
                         throws java.lang.Exception

Deprecated.

Returns the size of the file content (in bytes).

Specified by:

doGetContentSize in class AbstractFileObject<FS extends HttpFileSystem>

Returns:

The size of the file in bytes.

Throws:

java.lang.Exception - if an error occurs.

doGetInputStream

protected java.io.InputStream doGetInputStream(int bufferSize)
                                        throws java.lang.Exception

Deprecated.

Creates an input stream to read the file content from. Is only called if 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<FS extends HttpFileSystem>

Parameters:

bufferSize - Buffer size hint.

Returns:

An InputStream to read the file content.

Throws:

java.lang.Exception - if an error occurs.

doGetLastModifiedTime

protected long doGetLastModifiedTime()
                              throws java.lang.Exception

Deprecated.

Returns the last modified time of this file.

This implementation throws an exception.

Overrides:

doGetLastModifiedTime in class AbstractFileObject<FS extends HttpFileSystem>

Returns:

The last modification time.

Throws:

java.lang.Exception - if an error occurs.

doGetRandomAccessContent

protected RandomAccessContent doGetRandomAccessContent(RandomAccessMode mode)
                                                throws java.lang.Exception

Deprecated.

Description copied from class: AbstractFileObject

Creates access to the file for random i/o. 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.

Overrides:

doGetRandomAccessContent in class AbstractFileObject<FS extends HttpFileSystem>

Parameters:

mode - The mode to access the file.

Returns:

The RandomAccessContext.

Throws:

java.lang.Exception - if an error occurs.

doGetType

protected FileType doGetType()
                      throws java.lang.Exception

Deprecated.

Specified by:

doGetType in class AbstractFileObject<FS extends HttpFileSystem>

Returns:

the type of the file.

Throws:

java.lang.Exception - if an error occurs.

doIsWriteable

protected boolean doIsWriteable()
                         throws java.lang.Exception

Deprecated.

Description copied from class: AbstractFileObject

Determines if this file can be written to. Is only called if AbstractFileObject.doGetType() does not return FileType.IMAGINARY.

This implementation always returns true.

Overrides:

doIsWriteable in class AbstractFileObject<FS extends HttpFileSystem>

Returns:

true if the file is writable.

Throws:

java.lang.Exception - if an error occurs.
