file

protected File file

Deprecated.

The underlying file.

Constructor Detail

FileSource

public FileSource(String url,
                  ComponentManager manager)

Deprecated.

Create a file source from a 'file:' url and a component manager.

Method Detail

exists

public boolean exists()

Deprecated.

Description copied from class: AbstractStreamSource

Returns true if getInputStream() succeeds. Subclasses can provide a more efficient implementation.

Specified by:

exists in interface WriteableSource

Overrides:

exists in class AbstractStreamSource

Returns:

true if the resource exists.

isHTMLContent

protected boolean isHTMLContent()

Deprecated.

Returns true if the file name ends with ".htm" or ".html".

Overrides:

isHTMLContent in class AbstractStreamSource

getSystemId

public String getSystemId()

Deprecated.

Return the unique identifer for this source

Specified by:

getSystemId in interface Source

getInputStream

public InputStream getInputStream()
                           throws IOException,
                                  ProcessingException

Deprecated.

Get the input stream for this source.

Specified by:

getInputStream in interface Source

Throws:

IOException

ProcessingException

getLastModified

public long getLastModified()

Deprecated.

Description copied from class: AbstractStreamSource

Override this method to set the Last Modification date

Specified by:

getLastModified in interface Source

Overrides:

getLastModified in class AbstractStreamSource

getContentLength

public long getContentLength()

Deprecated.

Description copied from class: AbstractStreamSource

Override this method to set the Content Length

Specified by:

getContentLength in interface Source

Overrides:

getContentLength in class AbstractStreamSource

getOutputStream

public OutputStream getOutputStream()
                             throws IOException,
                                    ProcessingException

Deprecated.

Get an output stream to write to this source. The output stream returned actually writes to a temp file that replaces the real one on close. This temp file is used as lock to forbid multiple simultaneous writes. The real file is updated atomically when the output stream is closed.

Specified by:

getOutputStream in interface WriteableSource

Returns:

a stream to write to

Throws:

ConcurrentModificationException - if another thread is currently writing to this file.

IOException

ProcessingException

canCancel

public boolean canCancel(OutputStream stream)

Deprecated.

Always return false. To be redefined by implementations that support cancel().

Specified by:

canCancel in interface WriteableSource

Overrides:

canCancel in class AbstractStreamWriteableSource

Returns:

true if the stream can be cancelled

cancel

public void cancel(OutputStream stream)
            throws Exception

Deprecated.

Cancels the output stream.

Specified by:

cancel in interface WriteableSource

Overrides:

cancel in class AbstractStreamWriteableSource

Throws:

Exception
