Create an empty string.
Create a new string and initialize the string’s data with the supplied char buffer.
char* str | Null terminated character buffer |
Create a new string and initialize the string’s data with the contents of the supplied string.
mwString& str | Initialized mwString instance |
Return the number of characters in string.
mwString str("This is a string");
int len = str.Length();Return a pointer to internal buffer of string.
mwString str("This is a string");
const char* pstr = (const char*)str;Copy the contents of one string into a new string.
mwString& str | Initialized mwString instance to copy |
mwString str("This is a string");
mwString new_str = str;Copy the contents of a null terminated character buffer into a new string.
char* str | Null terminated character buffer to copy |
const char* pstr = "This is a string"; mwString str = pstr;
Test two mwString instances for equality.
If the characters in the string are the same, the instances are equal.
mwString& str | Initialized mwString instance |
mwString str("This is a string");
mwString str2("This is another string");
bool ret = (str == str2);Test two mwString instances for inequality.
If the characters in the string are not the same, the instances are
inequal.
mwString& str | Initialized mwString instance |
mwString str("This is a string");
mwString str2("This is another string");
bool ret = (str != str2);Compare two strings and return true if the
first string is lexicographically less than the second string.
mwString& str | Initialized mwString instance |
mwString str("This is a string");
mwString str2("This is another string");
bool ret = (str < str2);Compare two strings and return true if the
first string is lexicographically less than or equal to the second
string.
mwString& str | Initialized mwString instance |
mwString str("This is a string");
mwString str2("This is another string");
bool ret = (str <= str2);Compare two strings and return true if the
first string is lexicographically greater than the second string.
mwString& str | Initialized mwString instance |
mwString str("This is a string");
mwString str2("This is another string");
bool ret = (str > str2);Compare two strings and return true if the
first string is lexicographically greater than or equal to the second
string.
mwString& str | Initialized mwString instance |
mwString str("This is a string");
mwString str2("This is another string");
bool ret = (str >= str2);Copy contents of input string to specified ostream.
std::ostream& os | Initialized ostream instance to copy string
into |
mwString& str | Initialized mwString instance to copy |
#include <ostream>
mwString str("This is a string");
std::cout << str << std::endl;
