    • parse

      @Nullable public T parse(ParserContext context)
      Description copied from interface: Parser
      The core of the parsing logic. The context argument specifies where in the input string we are currently parsing. The responsibility of this function is to do one of:
      • Consume a part of the input and return a non-null value.
      • Return null and keep the input context untouched. This can be achieved either by avoiding the calls to ParserContext.advance(int), or through the use of snapshotting (see ParserContext.snapshot()).
      Specified by:
      parse in interface Parser<T>
      Parameters:
      context - Context of the parser containing the parsed string and the position in that string.
      Returns:
      Null-value if this parser did not match anything. Non-null if it matched.
