question: private final short validatePermSplitFactor ( String splitFactor ) throws AdeFlowException { short permSplitFactor = Short . parseShort ( splitFactor ) ; if ( permSplitFactor <= 0 || ( ( m_outerFramingFlow . getDuration ( ) / permSplitFactor ) < MILLISECONDS_IN_ONE_MINUTE ) ) { throw new AdeFlowException ( "Permanent Split Factor cannot be negative or 0." ) ; } return permSplitFactor ; }
target:  Validation for the permanent split factor. The split factor must be a positive short number  and must be less than or equal to the number of minutes in the analysis flow duration.
