question: private void parseParameter ( String token , String value ) { if ( token != null && value != null ) { if ( token . equalsIgnoreCase ( NONCE_TOKEN ) ) { mNonce = value ; return ; } if ( token . equalsIgnoreCase ( STALE_TOKEN ) ) { parseStale ( value ) ; return ; } if ( token . equalsIgnoreCase ( OPAQUE_TOKEN ) ) { mOpaque = value ; return ; } if ( token . equalsIgnoreCase ( QOP_TOKEN ) ) { mQop = value . toLowerCase ( ) ; return ; } if ( token . equalsIgnoreCase ( ALGORITHM_TOKEN ) ) { mAlgorithm = value . toLowerCase ( ) ; return ; } } }
target:  If the token is a known parameter name, parses and initializes the token value.
