Method ExternalLen

be/src/runtime/string-value.h:103–105

Returns the number of bytes needed outside the slot itself: - if the length is too long to smallify, return length - if the length is small enough to smallify: - if assume_smallify is true or the string is already smallified return 0 - otherwise (not already smallified and assume_smallify is false) return length

  ///   - if assume_smallify is true or the string is already smallified return 0
  ///   - otherwise (not already smallified and assume_smallify is false) return length
  int ExternalLen(bool assume_smallify) const {
    return string_impl_.ExternalLen(assume_smallify);
  }

  /// Sets the length of this String object. Length can only be decreased.
  void SetLen(int len) { return string_impl_.SetLen(len); }
