Class CosMultipartWrapper

java.lang.Object

net.sourceforge.stripes.controller.multipart.CosMultipartWrapper

All Implemented Interfaces:

MultipartWrapper

public class CosMultipartWrapper
extends Object
implements MultipartWrapper

Implementation of MultipartWrapper that uses Jason Hunter's COS (com.oreilly.servlet) multipart parser implementation. This is the default implementation in Stripes and is generally preferred as it is a) free for use and b) has no other dependencies! However, commercial redistribution of the COS library requires licensing from Jason Hunter, so this implementation may not be applicable for commercial products that are distributed/sold (though it is fine for commercial applications that are simply developed and hosted by the company developing them).

Since:

Stripes 1.4

Method Detail

build

public void build(HttpServletRequest request,
         File tempDir,
         long maxPostSize)
           throws IOException,
                  FileUploadLimitExceededException

Pseudo-constructor that allows the class to perform any initialization necessary.

Specified by:

build in interface MultipartWrapper

Parameters:

request - an HttpServletRequest that has a content-type of multipart.

tempDir - a File representing the temporary directory that can be used to store file parts as they are uploaded if this is desirable

maxPostSize - the size in bytes beyond which the request should not be read, and a FileUploadLimitExceeded exception should be thrown

Throws:

IOException - if a problem occurs processing the request of storing temporary files

FileUploadLimitExceededException - if the POST content is longer than the maxPostSize supplied.

getParameterNames

public Enumeration<String> getParameterNames()

Fetches the names of all non-file parameters in the request. Directly analogous to the method of the same name in HttpServletRequest when the request is non-multipart.

Specified by:

getParameterNames in interface MultipartWrapper

Returns:

an Enumeration of all non-file parameter names in the request

getParameterValues

public String[] getParameterValues(String name)

Fetches all values of a specific parameter in the request. To simulate the HTTP request style, the array should be null for non-present parameters, and values in the array should never be null - the empty String should be used when there is value.

Specified by:

getParameterValues in interface MultipartWrapper

Parameters:

name - the name of the request parameter

Returns:

an array of non-null parameters or null

getFileParameterNames

public Enumeration<String> getFileParameterNames()

Fetches the names of all file parameters in the request. Note that these are not the file names, but the names given to the form fields in which the files are specified.

Specified by:

getFileParameterNames in interface MultipartWrapper

Returns:

the names of all file parameters in the request.

getFileParameterValue

public FileBean getFileParameterValue(String name)

Responsible for constructing a FileBean object for the named file parameter. If there is no file parameter with the specified name this method should return null.

Specified by:

getFileParameterValue in interface MultipartWrapper

Parameters:

name - the name of the file parameter

Returns:

a FileBean object wrapping the uploaded file
