Member Function Documentation

expand_or_shrink_by()

int lolly::data::string_u16_rep::expand_or_shrink_by

(

int

delta

)

expand (or shrink) string by delta, but do not release memory when string is shrinked.

Returns

string length before expansion

Definition at line 55 of file string_u16.cpp.

                                              {
  int old_n= n;
  n+= delta;
  reserve (n);
  return old_n;
}

resize()

void lolly::data::string_u16_rep::resize

(

int

n

)

expand (or shrink) string to given length n, and try to release memory when string is shrinked.

Note

expand_or_shrink_by may be faster if memory space is reserved

Definition at line 31 of file string_u16.cpp.

                             {
  int nn= round_length (n);
  int mm= round_length (m);

  }

}

reserve()

void lolly::data::string_u16_rep::reserve

(

int

n

)

reserve memory space to contain at least n word in the whole string. Do not affect length of string, and do not release memory when n is smaller than current space.

Definition at line 63 of file string_u16.cpp.
