};

const int length

This member is the length of the string, as would be returned by strlen (does not include the terminating null character).

UtilString()

This constructor creates an empty UtilString. Note that this is not particularly useful, since UtilStrings are not mutable.

UtilString(const char* x)

This construcor creates a UtilString from x. Note that x is copied when the UtilString is made, so x can be freed or modified or whatever without hurting the UtilString.

~UtilString()

The destructor destroys the UtilString.

bool operator==(const UtilString& x)

This operator compares the string with x.

bool operator==(const char* x)

This operator compares the string with x.

char operator[](int x)

This operator allows accessing elements of the string, just as you would expect. Accessing elements less than zero or greater than length is guaranteed not to crash, but otherwise not defined.

operator const char*()

This conversion operator allows converting a UtilString into a const char*.
