                     throws Exception

doUpload

public static void doUpload(Database db,
                            boolean useTx,

                     throws Exception

Generic file upload. This function will create a new MolgenisFile object in the database, as well as put the referenced file source for this MolgenisFile in the correct place. The 'type' must correspond to the name of a subclass of MolgenisFile. Fields and types are dynamically checked and casted.

Parameters:

db - The database to use.

name - Full name of the original file (eg. 'mypicture.png')

type - Type of the file. Must correspond to a MolgenisFile subclass. (eg. 'Image' or 'BinaryDataMatrix') Used as part of the storage location. (eg. {storagedir}/{deployname}/image)

content - Any existing file of which only the content is submitted to the upload.

extraFields - A hashmap containing values of the additional fields that are used by this subclass of MolgenisFile. For example, 'investigation_name' for Image.

Throws:

Exception
