Method Detail

getSizeEstimation

long getSizeEstimation()

Return an estimated file size here to improve efficiency, otherwise we will do the first NSF object allocation with a default size (1.000.000 bytes) and auto-grow / -shrink it based on the produced file data.

Returns:

size estimation or -1 if unknown
