Method Detail

init

public void init(Configuration config)
          throws Exception

Invoked directly after instantiation to allow the configured component to perform one time initialization. Components are expected to fail loudly if they are not going to be in a valid state after initialization.

Specified by:

init in interface ConfigurableComponent

Parameters:

config - the Configuration object being used by Stripes

Throws:

Exception - should be thrown if the component cannot be configured well enough to use.

wrap

public MultipartWrapper wrap(HttpServletRequest request)
                      throws IOException,
                             FileUploadLimitExceededException

Wraps the request in an appropriate implementation of MultipartWrapper that is capable of providing access to request parameters and any file parts contained within the request.

Specified by:

wrap in interface MultipartWrapperFactory

Parameters:

request - an active HttpServletRequest

Returns:

an implementation of the appropriate wrapper

Throws:

IOException - if encountered when consuming the contents of the request

FileUploadLimitExceededException - if the post size of the request exceeds any configured limits
