Method Detail

getInputStream

java.io.InputStream getInputStream()
                                   throws java.io.IOException
Gets the content of this part as an InputStream

Returns:
The content of this part as an InputStream
Throws:
java.io.IOException - If an error occurs in retrieving the contet as an InputStream

getContentType

java.lang.String getContentType()
Gets the content type of this part.

Returns:
The content type of this part.

getName

java.lang.String getName()
Gets the name of this part

Returns:
The name of this part as a String

getSize

long getSize()
Returns the size of this fille.

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

write

void write(java.lang.String fileName)
           throws java.io.IOException
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.

Parameters:
fileName - the name of the file to which the stream will be written. The file is created relative to the location as specified in the MultipartConfig
Throws:
java.io.IOException - if an error occurs.

delete

void delete()
            throws java.io.IOException
Deletes the underlying storage for a file item, including deleting any associated temporary disk file.

Throws:
java.io.IOException - if an error occurs.

getHeader

java.lang.String getHeader(java.lang.String name)
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.

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

java.util.Collection<java.lang.String> getHeaders(java.lang.String name)
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.

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

java.util.Collection<java.lang.String> getHeaderNames()
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.

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