UploadPart

public UploadPart(FileItem fileItem)

Method Detail

getContentType

public String getContentType()

Description copied from interface: IUploadFile

Returns the MIME type specified when the file was uploaded. May return null if the content type is not known.

Specified by:

getContentType in interface IUploadFile

getFileName

public String getFileName()

Leverages Fileto convert the full file path and extract the name.

Specified by:

getFileName in interface IUploadFile

getFilePath

public String getFilePath()

Description copied from interface: IUploadFile

Returns the complete path, as reported by the client browser. Different browsers report different things here.

Specified by:

getFilePath in interface IUploadFile

Since:

2.0.4

getStream

public InputStream getStream()

Description copied from interface: IUploadFile

Returns an input stream of the content of the file. There is no guarantee that this stream will be valid after the end of the current request cycle, so it should be processed immediately.

As of release 1.0.8, this will be a a ByteArrayInputStream, but that, too, may change (a future implementation may upload the stream to a temporary file and return an input stream from that).

Specified by:

getStream in interface IUploadFile

cleanup

public void cleanup()

Deletes the external content file, if one exists.

write

public void write(File file)

Writes the uploaded content to a file. This should be invoked at most once (perhaps we should add a check for this). This will often be a simple file rename.

Specified by:

write in interface IUploadFile

Since:

getSize

public long getSize()

Description copied from interface: IUploadFile

Returns the size, in bytes, of the uploaded content.

Specified by:

getSize in interface IUploadFile

Since:

isInMemory

public boolean isInMemory()

Description copied from interface: IUploadFile

Returns true if the uploaded content is in memory. False generally means the content is stored in a temporary file.

Specified by:

isInMemory in interface IUploadFile

Since:
