question: private void addOneLineOfTLA ( String line ) { if ( tlacode . size ( ) != mappingVector . size ( ) ) { PcalDebug . ReportBug ( "tlacode and mappingVector have different lengths" ) ; } endCurrentLineOfTLA ( ) ; if ( line . length ( ) == 0 ) { mappingVector . addElement ( new Vector ( 2 ) ) ; tlacode . addElement ( "" ) ; return ; } addOneTokenToTLA ( line ) ; endCurrentLineOfTLA ( ) ; }
target:  Adds a complete line of TLA "code" that does not correspond to any PlusCal code.  Adds Begin/EndTLAToken objects to the mapping iff the line does not equal "".
