Constructor Detail

MultiPartHandler

public MultiPartHandler(MultiPartHandler.RequestFacade request,
                        String tmpDirectory)
                 throws IOException

Instantiate a new multipart handler with default

Throws:

IOException

---

MultiPartHandler

public MultiPartHandler(MultiPartHandler.RequestFacade request,
                        String tmpDirectory,
                        int maxUploadSize)
                 throws IOException

Throws:

IOException

MultiPartHandler

public MultiPartHandler(MultiPartHandler.RequestFacade request,
                        String tmpDirectory,
                        int maxUploadSize,
                        String fieldEncoding)
                 throws IOException

Instantiate a new OneUpload to handle the given request, saving any uploaded files to the given directory and limiting the upload size to maxUploadSize. An IOException is thrown when the request content-type doesn't match with multipart/form-data or if the upload size exceeds the given limit. call parseMultipartUpload() to parse various parts of the posted data and then call getParameter(), getParameters(), getParameterNames() and getParameterValues() functions to access form field names and their values. call getFile(), getFileType() to access uploaded file and its content-type.

Throws:

IOException

Method Detail

parseMultipartUpload

public void parseMultipartUpload()
                          throws IOException

Throws:

IOException

---

getParameterNames

public Enumeration getParameterNames()

Returns the names of all the parameters as an Enumeration of Strings. It returns an empty Enumeration if there are no parameters.

---

getFileNames

public Enumeration getFileNames()

Returns the names of all the uploaded files as an Enumeration of Strings. It returns an empty Enumeration if there are no uploaded files. Each file name is the name specified by the form, not by the user.

---

getParameter

public String getParameter(String name)

Returns the value of the named parameter as a String, or null if the parameter was not sent or was sent without a value. The value is guaranteed to be in its normal, decoded form. If the parameter has multiple values, only the last one is returned (for backward compatibility). For parameters with multiple values, it's possible the last "value" may be null.

---

getParameterValues

public String[] getParameterValues(String name)

Returns the values of the named parameter as a String array, or null if the parameter was not sent. The array has one entry for each parameter field sent. If any field was sent without a value that entry is stored in the array as a null. The values are guaranteed to be in their normal, decoded form. A single value is returned as a one-element array.

---

getFileName

public String getFileName(String name)

Returns the filesystem name of the specified file, or null if the file was not included in the upload. A filesystem name is the name specified by the user. It is also the name under which the file is actually saved.

---

getFileType

public String getFileType(String name)

Returns the content type of the specified file (as supplied by the client browser), or null if the file was not included in the upload.

---

getFile

public File getFile(String name)

Returns a File object for the specified file saved on the server's filesystem, or null if the file was not included in the upload.

---

close

public void close()
           throws IOException

close the multi-part form handler

Throws:

IOException
