# log4cpp::StringUtil Class Reference

`#include <StringUtil.hh>`

List of all members.

## Static Public Member Functions
static std::string | vform (const char *format, va_list args)
| Returns a string contructed from the a format specifier and a va_list of arguments, analogously to vprintf(3).
static std::string | trim (const std::string &s)
| Returns a string identical to the given string but without leading or trailing HTABs or spaces.
static unsigned int | split (std::vector< std::string > &v, const std::string &s, char delimiter, unsigned int maxSegments=INT_MAX)
| splits a string into a vector of string segments based on the given delimiter.
template<typename T>
static unsigned int | split (T &output, const std::string &s, char delimiter, unsigned int maxSegments=INT_MAX)
| splits a string into string segments based on the given delimiter and assigns the segments through an output_iterator.

## Member Function Documentation

std::string log4cpp::StringUtil::vform | ( | const char * | format,
|  | va_list | args |
| ) |  |  | `[static]`

Returns a string contructed from the a format specifier and a va_list of arguments, analogously to vprintf(3).

Parameters:

  | format | the format specifier.
  | args | the va_list of arguments.

std::string log4cpp::StringUtil::trim | ( | const std::string & | s | ) | `[static]`

Returns a string identical to the given string but without leading or trailing HTABs or spaces.

unsigned int log4cpp::StringUtil::split | ( | std::vector< std::string > & | v,
|  | const std::string & | s,
|  | char | delimiter,
|  | unsigned int | maxSegments = `INT_MAX` |
| ) |  |  | `[static]`

splits a string into a vector of string segments based on the given delimiter.

Parameters:

  | v | The vector in which the segments will be stored. The vector will be emptied before storing the segments
  | s | The string to split into segments.
  | delimiter | The delimiter character
  | maxSegments | the maximum number of segments. Upon return v.size() <= maxSegments. The string is scanned from left to right so v[maxSegments - 1] may contain a string containing the delimiter character.

Returns:
  The actual number of segments (limited by maxSegments).

template<typename T>

static unsigned int log4cpp::StringUtil::split | ( | T & | output,
|  | const std::string & | s,
|  | char | delimiter,
|  | unsigned int | maxSegments = `INT_MAX` |
| ) |  |  | `[inline, static]`

splits a string into string segments based on the given delimiter and assigns the segments through an output_iterator.

Parameters:

  | output | The output_iterator through which to assign the string segments. Typically this will be a back_insertion_iterator.
  | s | The string to split into segments.
  | delimiter | The delimiter character
  | maxSegments | The maximum number of segments.

Returns:
  The actual number of segments (limited by maxSegments).
