Method Detail

getInputStream

public InputStream getInputStream()
                           throws IOException

Description copied from interface: Part

Gets the content of this part as an InputStream

Specified by:

getInputStream in interface Part

Returns:

The content of this part as an InputStream

Throws:

IOException - If an error occurs in retrieving the content as an InputStream

getContentType

public String getContentType()

Description copied from interface: Part

Gets the content type of this part.

Specified by:

getContentType in interface Part

Returns:

The content type of this part.

getName

public String getName()

Description copied from interface: Part

Gets the name of this part

Specified by:

getName in interface Part

Returns:

The name of this part as a String

getSubmittedFileName

public String getSubmittedFileName()

Description copied from interface: Part

Gets the file name specified by the client

Specified by:

getSubmittedFileName in interface Part

Returns:

the submitted file name

getSize

public long getSize()

Description copied from interface: Part

Returns the size of this fille.

Specified by:

getSize in interface Part

Returns:

a long specifying the size of this part, in bytes.

write

public void write(String fileName)
           throws IOException

Description copied from interface: Part

A convenience method to write this uploaded item to disk.

This method is not guaranteed to succeed if called more than once for the same part. This allows a particular implementation to use, for example, file renaming, where possible, rather than copying all of the underlying data, thus gaining a significant performance benefit.

Specified by:

write in interface Part

Parameters:

fileName - The location into which the uploaded part should be stored. The value may be a file name or a path. The actual location of the file in the filesystem is relative to MultipartConfigElement.getLocation(). Absolute paths are used as provided and are relative to getLocation(). Note: that this is a system dependent string and URI notation may not be acceptable on all systems. For portability, this string should be generated with the File or Path APIs.

Throws:

IOException - if an error occurs.

delete

public void delete()
            throws IOException

Description copied from interface: Part

Deletes the underlying storage for a file item, including deleting any associated temporary disk file.

Specified by:

delete in interface Part

Throws:

IOException - if an error occurs.

getHeader

public String getHeader(String name)

Description copied from interface: Part

Returns the value of the specified mime header as a String. If the Part did not include a header of the specified name, this method returns null. If there are multiple headers with the same name, this method returns the first header in the part. The header name is case insensitive. You can use this method with any request header.

Specified by:

getHeader in interface Part

Parameters:

name - a String specifying the header name

Returns:

a String containing the value of the requested header, or null if the part does not have a header of that name

getHeaders

public Collection<String> getHeaders(String name)

Description copied from interface: Part

Gets the values of the Part header with the given name.

Any changes to the returned Collection must not affect this Part.

Part header names are case insensitive.

Specified by:

getHeaders in interface Part

Parameters:

name - the header name whose values to return

Returns:

a (possibly empty) Collection of the values of the header with the given name

getHeaderNames

public Collection<String> getHeaderNames()

Description copied from interface: Part

Gets the header names of this Part.

Some servlet containers do not allow servlets to access headers using this method, in which case this method returns null

Any changes to the returned Collection must not affect this Part.

Specified by:

getHeaderNames in interface Part

Returns:

a (possibly empty) Collection of the header names of this Part
