Detailed Description

class String A safe string class.

Copy and assignment are deep. Memory is deleted upon a destructor call.

---

Constructor & Destructor Documentation

String::String (   )  [inline]

Create an empty string

String::String (  char  c  )  [inline]

Create a null-terminated string with one character

String::String (  const char *  str  )  [inline]

Create by copying a null-terminated C string

String::String (  const char *  str, int  len )  [inline]

Create by copying a certain number of elements from a C string

---

Member Function Documentation

String String::after (  const String &  sub  )  const [inline]

return the substring after the first occurance of a string

String String::after (  const char *  sub  )  const [inline]

return the substring after the first occurance of a string

bool String::atob (   )  const [inline]

Bool value

double String::atof (   )  const [inline]

Double value

int String::atoi (   )  const [inline]

Integer value

String String::before (  const String &  sub  )  const [inline]

return the substring before the first occurance of a string

String String::before (  const char *  sub  )  const [inline]

return the substring before the first occurance of a string

String String::beforeToken (  const String &  tokens  )  const [inline]

return the string before the first occurance of one of the characters in the token string

String String::between (  const String &  begin, const String &  end, String &  front, String &  back )  const [inline]

return the substring between a beginning and ending delimiter. Return by reference the substrings before and after the beginning and ending delimiters. For example path = "abc(def)hij".between("(", ")", front, back) returns the string "def" and sets front and back to "abc" and "hij".

int String::byteCount (   )  const [inline]

get number of bytes in string

bool String::contains (  char  c  )  const [inline]

decide if a string contains a character

const char * String::cString (   )  const [inline]

Access to pointer to C string. Use with care.

int String::find (  const String &  sub  )  const [inline]

Find the location of a substring, returning -1 if not found

int String::find (  const char *  sub  )  const [inline]

Find the location of a substring, returning -1 if not found

int String::hashCode (   )  const [inline]

Compute a hash code for the string

int String::length (   )  const [inline]

return number of non-null characters

bool String::operator!= (  const String &  other  )  const [inline]

Check inequality of contents

String String::operator+ (  const double &  x  )  const [inline]

Concatenation

String String::operator+ (  const int &  x  )  const [inline]

Concatenation

String String::operator+ (  const String &  other  )  const [inline]

Concatenation

String & String::operator+= (  const String &  other  )  [inline]

In-place concatenation

bool String::operator< (  const String &  other  )  const [inline]

Lexical less-than comparison

bool String::operator== (  const String &  other  )  const [inline]

Check equality of contents

char & String::operator[] (  int  i  )  [inline]

Read/Writer access

const char & String::operator[] (  int  i  )  const [inline]

Read-only access

String String::subString (  int  begin, int  end )  const [inline]

grab a substring between two locations

String String::toString (   )  const [inline]

Return String form of object.
