​
split

static 
static inline size_t split(const std::string & s, std::vector< std::string > & result, const std::string & delim, bool keep_empty, bool trim_space)
Split string by delimiter with optional trimming.

​
Parameters

  • s Input string
  • result Output vector (appends to existing elements)
  • delim Delimiter string
  • keep_empty Keep empty tokens
  • trim_space Trim whitespace from each token

​
Returns

Number of characters processed Example: 
std::vector<std::string> parts;
[StringUtils::split](#split)("drone1,drone2, drone3", parts, ",");
// parts = {"drone1", "drone2", "drone3"}

​
split

static 
static inline size_t split(const std::string & s, std::vector< std::string > & result, char delim, bool keep_empty, bool trim_space)
