CXString
From cxwiki
The CXString class is considered the "default" string class in the cxsource framework. It offers a reasonable compromise of capabilities. Other string classes are available for more specific uses where the standard tradeoffs are not suitable.
A CXString object nominally stores UTF-8 encoded text with a zero termination byte. Strings are stored using copy-on-write references, and string pooling may optionally be enabled using a compile-time flag. CXString objects do not distinguish "null" and "empty" strings.
Construction
// Efficiently construct an empty string.
CXString(void);
// Construct from a cxsource string object.
CXString(const CXString &str);
CXString(CXString&& rhs);
CXString(const class CXStringEdit& str);
CXString(const CXStringArgument& cstr);
// Construct from a character range.
CXString(const CXStringArgument& begin, const CXStringArgument& end);
CXString(const char* __nullable ch, size_t len);
CXString(const char* __nonnull ch, const char* __nonnull end);
// Construct from Objective-C string or data objects.
CXString(NSString* __nullable str);
CXString(NSData* __nullable data);
// Construct from a printf-style format string.
static CXString Fromf(const char* __nonnull format, ...);
Equivalent assingment operators are also available.
