question: replacement operation . requires : t ! = null & & 0 e.g. given a rattermvec v = t2 , t3 , t4 , the statement `` v.set t5 , 1 ; '' will make v_post = t2 , t5 , t4 . concode_field_sep Vector underlying_terms concode_elem_sep RatTerm[] terms concode_field_sep int size concode_elem_sep String printDebug concode_elem_sep boolean equals concode_elem_sep RatTerm get concode_elem_sep void insert concode_elem_sep String toString concode_elem_sep void addElement concode_elem_sep RatTermVec copy concode_elem_sep void remove
target: void function ( RatTerm arg0 , int arg1 ) { underlying_terms . setElementAt ( arg0 , arg1 ) ; terms = ( RatTerm [ ] ) underlying_terms . toArray ( new RatTerm [ ] { } ) ; }
