Throws:

FileSystemException - if any error occurs

Http4FileObject

protected Http4FileObject(AbstractFileName name,
 FS fileSystem,
 Http4FileSystemConfigBuilder builder)
                   throws FileSystemException

Method Details

doDetach

protected void doDetach()
                 throws Exception

Deprecated.

Description copied from class: AbstractFileObject

Detaches this file object from its file resource.

Called when this file is closed. Note that the file object may be reused later, so should be able to be reattached.

This implementation does nothing.

Overrides:

doDetach in class AbstractFileObject<FS extends Http4FileSystem>

Throws:

Exception - if an error occurs.

doGetContentSize

protected long doGetContentSize()
                         throws Exception

Deprecated.

Description copied from class: AbstractFileObject

Returns the size of the file content (in bytes). Is only called if AbstractFileObject.doGetType() returns FileType.FILE.

Specified by:

doGetContentSize in class AbstractFileObject<FS extends Http4FileSystem>

Returns:

The size of the file in bytes.

Throws:

Exception - if an error occurs.

doGetInputStream

protected InputStream doGetInputStream(int bufferSize)
                                throws Exception

Deprecated.

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<FS extends Http4FileSystem>

Parameters:

bufferSize - Buffer size hint.

Returns:

An InputStream to read the file content.

Throws:

Exception - if an error occurs.

doGetLastModifiedTime

protected long doGetLastModifiedTime()
                              throws Exception

Deprecated.

Description copied from class: AbstractFileObject

Returns the last modified time of this file. Is only called if AbstractFileObject.doGetType() does not return

This implementation throws an exception.

Overrides:

doGetLastModifiedTime in class AbstractFileObject<FS extends Http4FileSystem>

Returns:

The last modification time.

Throws:

Exception - if an error occurs.

doGetRandomAccessContent

protected RandomAccessContent doGetRandomAccessContent(RandomAccessMode mode)
                                                throws 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 Http4FileSystem>

Parameters:

mode - The mode to access the file.

Returns:

The RandomAccessContext.

Throws:

Exception - if an error occurs.

doGetType

protected FileType doGetType()
                      throws Exception

Deprecated.

Description copied from class: AbstractFileObject

Determines the type of this file. Must not return null. The return value of this method is cached, so the implementation can be expensive.

Specified by:

doGetType in class AbstractFileObject<FS extends Http4FileSystem>

Returns:

the type of the file.

Throws:

Exception - if an error occurs.

doIsWriteable

protected boolean doIsWriteable()
                         throws 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 Http4FileSystem>

Returns:

true if the file is writable.

Throws:

Exception - if an error occurs.

doListChildren

protected String[] doListChildren()
                           throws Exception

Deprecated.

Description copied from class: AbstractFileObject

Lists the children of this file. Is only called if AbstractFileObject.doGetType() returns FileType.FOLDER. The return value of this method is cached, so the implementation can be expensive.

Specified by:

doListChildren in class AbstractFileObject<FS extends Http4FileSystem>

Returns:

a possible empty String array if the file is a directory or null or an exception if the file is not a directory or can't be read.

Throws:

Exception - if an error occurs.
