question: parses value of long argument from specified string . method does not validate argument , it just creates substring value separator to the end or returns null if value separator is not present concode_field_sep String PREFIX_SHORT concode_elem_sep String PREFIX_LONG concode_elem_sep Map<String,Argument> argMap concode_elem_sep String VALUE_SEP_LONG concode_field_sep void addArg concode_elem_sep String parseLongArgName concode_elem_sep boolean isShortArg concode_elem_sep boolean isLongArg concode_elem_sep Map<String,String> parse concode_elem_sep Map<String,String> parse
target: String function ( String arg0 ) { int loc0 = arg0 . indexOf ( VALUE_SEP_LONG ) ; if ( loc0 == - 1 ) { return null ; } else { return arg0 . substring ( loc0 + 1 ) ; } }
