question: protected boolean isEqualKey ( AbstractHashedMap . HashEntry entry , Object key1 , Object key2 , Object key3 , Object key4 , Object key5 ) { MultiKey multi = ( MultiKey ) entry . getKey ( ) ; return multi . size ( ) == 5 && ( key1 == null ? multi . getKey ( 0 ) == null : key1 . equals ( multi . getKey ( 0 ) ) ) && ( key2 == null ? multi . getKey ( 1 ) == null : key2 . equals ( multi . getKey ( 1 ) ) ) && ( key3 == null ? multi . getKey ( 2 ) == null : key3 . equals ( multi . getKey ( 2 ) ) ) && ( key4 == null ? multi . getKey ( 3 ) == null : key4 . equals ( multi . getKey ( 3 ) ) ) && ( key5 == null ? multi . getKey ( 4 ) == null : key5 . equals ( multi . getKey ( 4 ) ) ) ; }
target:  Is the key equal to the combined key.
