Method Detail

init

public static void init(java.lang.Integer maxUploadSize,
                        java.io.File diskCacheLocation,
                        java.lang.Integer memoryCacheThresholdSize)
                 throws java.io.IOException

Called once to initialize the factory.

Parameters:

maxUploadSize - Size, in bytes, of maximum allowable upload. Null or negetive values allow any sized upload. A value of zero will disable file uploading.

diskCacheLocation - Location to store uploaded files instead of holding them in memory. If this value is null, uploads will be stored in memory during the request processing.

memoryCacheThresholdSize - Size, in bytes, that a file upload must exceed for it to be stored to disk. A null, negative or zero value will force the file to always be cached to disk. This parameter is ignored if diskCacheLocation is null.

Throws:

java.io.IOException - if the discovered MultipartUploadSPI provider throws an IOException.

create

public static MultipartUploadSPI create()

Generates a new instance of the MultipartUploadSPI implementation.

Returns:

an instance of the MultipartUploadSPI
