DiskFileUpload
public class DiskFileUpload extends FileUploadBase (Code)

High level API for processing file uploads.

This class handles multiple files per single HTML widget, sent using multipart/mixed encoding type, as specified by RFC 1867. Use DiskFileUpload.parseRequest(HttpServletRequest) to acquire a list of org.apache.commons.fileupload.FileItem s associated with a given HTML widget.

Individual parts will be stored in temporary disk storage or in memory, depending on their size, and will be available as org.apache.commons.fileupload.FileItem s.

Constructor Summary
public  DiskFileUpload()
     Constructs an instance of this class which uses the default factory to create FileItem instances.
public  DiskFileUpload(DefaultFileItemFactory fileItemFactory)
     Constructs an instance of this class which uses the supplied factory to create FileItem instances.

Method Summary
public  FileItemFactorygetFileItemFactory()
     Returns the factory class used when creating file items.
public  StringgetRepositoryPath()
     Returns the location used to temporarily store files that are larger than the configured size threshold.
public  intgetSizeThreshold()
     Returns the size threshold beyond which files are written directly to disk.
public  ListparseRequest(HttpServletRequest req, int sizeThreshold, long sizeMax, String path)
     Processes an RFC 1867 compliant multipart/form-data stream.
public  voidsetFileItemFactory(FileItemFactory factory)
     Sets the factory class to use when creating file items.
public  voidsetRepositoryPath(String repositoryPath)
     Sets the location used to temporarily store files that are larger than the configured size threshold.
public  voidsetSizeThreshold(int sizeThreshold)
     Sets the size threshold beyond which files are written directly to disk.


Constructor Detail
DiskFileUpload
public DiskFileUpload()(Code)
Constructs an instance of this class which uses the default factory to create FileItem instances.
See Also:   DiskFileUpload.DiskFileUpload(DefaultFileItemFactory fileItemFactory)



DiskFileUpload
public DiskFileUpload(DefaultFileItemFactory fileItemFactory)(Code)
Constructs an instance of this class which uses the supplied factory to create FileItem instances.
See Also:   DiskFileUpload.DiskFileUpload()
Parameters:
  fileItemFactory - The file item factory to use.




Method Detail
getFileItemFactory
public FileItemFactory getFileItemFactory()(Code)
Returns the factory class used when creating file items. The factory class for new file items.



getRepositoryPath
public String getRepositoryPath()(Code)
Returns the location used to temporarily store files that are larger than the configured size threshold. The path to the temporary file location.
See Also:   DiskFileUpload.setRepositoryPath(String)



getSizeThreshold
public int getSizeThreshold()(Code)
Returns the size threshold beyond which files are written directly to disk. The size threshold, in bytes.
See Also:   DiskFileUpload.setSizeThreshold(int)



parseRequest
public List parseRequest(HttpServletRequest req, int sizeThreshold, long sizeMax, String path) throws FileUploadException(Code)
Processes an RFC 1867 compliant multipart/form-data stream. If files are stored on disk, the path is given by getRepository().
Parameters:
  req - The servlet request to be parsed. Must be non-null.
Parameters:
  sizeThreshold - The max size in bytes to be stored in memory.
Parameters:
  sizeMax - The maximum allowed upload size, in bytes.
Parameters:
  path - The location where the files should be stored. A list of FileItem instances parsed from therequest, in the order that they were transmitted.
throws:
  FileUploadException - if there are problems reading/parsingthe request or storing files.



setFileItemFactory
public void setFileItemFactory(FileItemFactory factory)(Code)
Sets the factory class to use when creating file items. The factory must be an instance of DefaultFileItemFactory or a subclass thereof, or else a ClassCastException will be thrown.
Parameters:
  factory - The factory class for new file items.



setRepositoryPath
public void setRepositoryPath(String repositoryPath)(Code)
Sets the location used to temporarily store files that are larger than the configured size threshold.
Parameters:
  repositoryPath - The path to the temporary file location.
See Also:   DiskFileUpload.getRepositoryPath()



setSizeThreshold
public void setSizeThreshold(int sizeThreshold)(Code)
Sets the size threshold beyond which files are written directly to disk.
Parameters:
  sizeThreshold - The size threshold, in bytes.
See Also:   DiskFileUpload.getSizeThreshold()
