Detailed Description

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.


Member Typedef Documentation


Constructor & Destructor Documentation

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 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 
)

Constructor that copies c into dynamically allocated memory.

ACE_SString::~ACE_SString ( void   ) 

Default destructor.


Member Function Documentation

const char * ACE_SString::c_str ( void   )  const

Same as STL String's <c_str> and <fast_rep>.

int ACE_SString::compare ( const ACE_SString s  )  const

Performs a <strcmp>-style comparison.

void ACE_SString::dump ( void   )  const

Dump the state of an object.

const char * ACE_SString::fast_rep ( void   )  const

Get the underlying pointer.

ACE_SString::size_type ACE_SString::find ( char  c,
size_type  pos = 0 
) const

Find c starting at pos. Returns the slot of the first location that matches (will be >= pos), else npos.

ACE_SString::size_type ACE_SString::find ( const char *  s,
size_type  pos = 0 
) const

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

ACE_SString::size_type ACE_SString::find ( const ACE_SString str,
size_type  pos = 0 
) const

Find str starting at pos. Returns the slot of the first location that matches (will be >= pos), else npos.

u_long ACE_SString::hash ( void   )  const

Returns a hash value for this string.

ACE_SString::size_type ACE_SString::length ( void   )  const

Return the length of the string.

bool ACE_SString::operator!= ( const ACE_SString s  )  const

Inequality comparison operator.

bool ACE_SString::operator< ( const ACE_SString s  )  const

Less than comparison operator.

ACE_SString & ACE_SString::operator= ( const ACE_SString s  ) 

Assignment operator (does copy memory).

bool ACE_SString::operator== ( const ACE_SString s  )  const

Equality comparison operator (must match entire string).

bool ACE_SString::operator> ( const ACE_SString s  )  const

Greater than comparison operator.

char & ACE_SString::operator[] ( size_type  slot  ) 

Return the <slot'th> character by reference in the string (doesn't perform bounds checking).

char ACE_SString::operator[] ( size_type  slot  )  const

Return the <slot'th> character in the string (doesn't perform bounds checking).

const char * ACE_SString::rep ( void   )  const

Get the underlying pointer.

void ACE_SString::rep ( char *  s  ) 

Set the underlying pointer. Since this does not copy memory or delete existing memory use with extreme caution!!!

ACE_SString::size_type ACE_SString::rfind ( char  c,
size_type  pos = npos 
) const

Find c starting at pos (counting from the end). Returns the slot of the first location that matches, else npos.

ACE_SString::size_type ACE_SString::strstr ( const ACE_SString s  )  const

Comparison operator that will match substrings. Returns the slot of the first location that matches, else npos.

ACE_SString ACE_SString::substr ( size_type  offset,
size_type  length = npos 
) const

Same as substring.

ACE_SString ACE_SString::substring ( size_type  offset,
size_type  length = npos 
) const

Return a substring given an offset and length, if length == npos use rest of str return empty substring if offset or offset/length are invalid
