Description copied from class: WebFileSystem

Transfers the file from the remote store to a local copy f. This should only be used within the class and subclasses, clients should use getFileObject( String ).getFile(). Subclasses implementing this should download data to partfile, then rename partfile to f after the download is complete. Note, this is non-trivial, since several threads and even several processes may be using the same area at once. See HttpFileSystem's implementation of this before attempting to implement the function.

Specified by:

downloadFile in class WebFileSystem

Parameters:

filename - the name of the file, relative to the filesystem.

targetFile - the file to where the file is downloaded.

partFile - the temporary file during download.

mon - progress monitor

Returns:

metadata headers from the load, if any are available. See WebProtocol.

Throws:

java.io.IOException

See Also:

WebProtocol.getMetadata(org.das2.util.filesystem.WebFileObject)

getFileObject

public FileObject getFileObject(java.lang.String filename)

Description copied from class: WebFileSystem

Return the handle for this file. This is not the file itself, and accessing this object does not necessarily download the resource. This will be a container for file metadata, in addition to providing access to the data file itself.

Overrides:

getFileObject in class WebFileSystem

Parameters:

filename - the name of the file within the filesystem.

Returns:

a FileObject for the file

getLogger

protected static final java.util.logging.Logger getLogger()
