Method Detail

createDataWriter

DataWriter createDataWriter(T owner,

                            throws IOException

Create a data writer for writing data that belongs to the given owner. The owner is typically a bioassay (serial bfs format) or a spot data field (matrix bfs format). The returned writer should usually have it's filename (DataWriter.getFilename()) and number of columns (DataWriter.getColumnCount()) set, since this is needed for the metadata generation.

Parameters:

owner - The object that "owns" the data that is written to the file

suggestedFilename - An optional suggested filename, the factory may use this string or generate a different filename

Returns:

A data writer object with the filename and number of colums set (unless otherwise specified)

Throws:

IOException
