Field Detail

contentType

protected String contentType

The content type of the file

fileName

protected String fileName

The name of the file

filePath

protected String filePath

The filepath to the temporary file

fileSize

protected int fileSize

The size in bytes of the file

Method Detail

destroy

public void destroy()

Delete the temporary file.

getContentType

public String getContentType()

Get the content type

Attempt to read the temporary file and get it's data in byte array form. Tries to read the entire file (using a byte array the size of getFileSize()) at once, in one call to FileInputStream.read(byte[]). For buffered reading, see getFileData(int). Note that this method can be dangerous, and that the size of a file can cause an OutOfMemoryError quite easily. You should use getInputStream and do your own thing.

Throws: FileNotFoundException If the temp file no longer exists IOException if there is some sort of IO problem.

getFileData

public byte[] getFileData(int bufferSize)

Attempts to read a file n bytes at a time, n being equal to "bufferSize". Note that this method can be dangerous, and that the size of a file can cause an OutOfMemoryError quite easily. You should use getInputStream and do your own thing.

Parameters: bufferSize The size in bytes that are read from the file at a time

Throws: FileNotFoundException If the temp file no longer exists

getFileName

public String getFileName()

Get the file name

getFilePath

public String getFilePath()

Get the temporary file path for this form file

Returns: A filepath to the temporary file

getFileSize

public int getFileSize()

Get the file size

Returns: The size of this file in bytes

Parameters: fileSize The size of the file in bytes
