question: @ Override public int compareTo ( ComponentDescription o ) { int myPos = 0 ; int oPos = 0 ; if ( this instanceof LanguageComponentDescription ) { myPos = 5 ; } else if ( this instanceof VoiceComponentDescription ) { myPos = 10 ; } if ( o instanceof LanguageComponentDescription ) { oPos = 5 ; } else if ( o instanceof VoiceComponentDescription ) { oPos = 10 ; } if ( oPos - myPos != 0 ) { return ( oPos - myPos ) ; } return name . compareTo ( o . name ) ; }
target:  Define a natural ordering for component descriptions. Languages first, in alphabetic order, then voices, in alphabetic order.
