A very Simple String ACE_SString class. This is not a general-purpose string class, and you should probably consider using ACE_CString is you don't understand why this class exists...
This class is optimized for efficiency, so it doesn't provide any internal locking. CAUTION: This class is only intended for use with applications that understand how it works. In particular, its destructor does not deallocate its memory when it is destroyed... We need this class since the ACE_Map_Manager requires an object that supports the operator == and operator !=. This class uses an ACE_Allocator to allocate memory. The user can make this a persistant class by providing an ACE_Allocator with a persistable memory pool.
ACE_SString::ACE_SString | ( | ACE_Allocator * | alloc = 0 | ) |
Default constructor.
ACE_SString::ACE_SString | ( | const char * | s, |
ACE_Allocator * | alloc = 0 |
||
) |
Constructor that copies s into dynamically allocated memory.
ACE_SString::ACE_SString | ( | const char * | s, |
size_type | len, | ||
ACE_Allocator * | alloc = 0 |
||
) |
Constructor that copies len chars of s into dynamically allocated memory (will NUL terminate the result).
ACE_SString::ACE_SString | ( | const ACE_SString & | s | ) |
Copy constructor.
ACE_SString::ACE_SString | ( | char | c, |
ACE_Allocator * | alloc = 0 |

|
inline |
Get the underlying pointer.
|
inline |
Find str starting at pos. Returns the slot of the first location that matches (will be >= pos), else npos.
|
inline |
Find <s> starting at pos. Returns the slot of the first location that matches (will be >= pos), else npos.

|
inline |
Return the <slot'th> character by reference in the string (doesn't perform bounds checking).
void ACE_SString::rep | ( | char * | s | ) |
Set the underlying pointer. Since this does not copy memory or delete existing memory use with extreme caution!!!
