Detailed Description

template<class ACE_CHAR_T>
class ACE_String_Base< ACE_CHAR_T >

This class provides a wrapper facade for C strings.

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. This class is optimized for efficiency, so it doesn't provide any internal locking.

Note:
If an instance of this class is constructed from or assigned an empty string (with first element of '\0'), then it is not allocated new space. Instead, its internal representation is set equal to a global empty string. CAUTION: in cases when ACE_String_Base is constructed from a provided buffer with the release parameter set to false, ACE_String_Base is not guaranteed to be '\0' terminated.

Constructor & Destructor Documentation

template<class ACE_CHAR_T >
ACE_String_Base< ACE_CHAR_T >::ACE_String_Base ( ACE_Allocator the_allocator = 0)

Default constructor.

Parameters:
the_allocatorACE_Allocator associated with string
Returns:
Default ACE_String_Base string.
template<class ACE_CHAR_T>
ACE_String_Base< ACE_CHAR_T >::ACE_String_Base ( const ACE_CHAR_T *  s,
ACE_Allocator the_allocator = 0,
bool  release = true 
)

Constructor that copies s into dynamically allocated memory.

if release == true then a new buffer is allocated internally, and s is copied to the internal buffer. if release == false then the s buffer is used directly. If s == 0 then it will _not_ be used, and instead the internal buffer is set to NULL_String_.

Parameters:
sZero terminated input string
the_allocatorACE_Allocator associated with string
releaseAllocator responsible(true)/not responsible(false) for freeing memory.
Returns:
ACE_String_Base containing const ACE_CHAR_T *s
template<class ACE_CHAR_T>
ACE_String_Base< ACE_CHAR_T >::ACE_String_Base ( const ACE_CHAR_T *  s,
size_type  len,
ACE_Allocator the_allocator = 0,
bool  release = true 
)

Constructor that copies len CHARs of s into dynamically allocated memory (will zero terminate the result).

if release == true then a new buffer is allocated internally. s is copied to the internal buffer. if release == false then the s buffer is used directly. If s == 0 then it will _not_ be used, and instead the internal buffer is set to NULL_String_.

Parameters:
sNon-zero terminated input string
lenLength of non-zero terminated input string
the_allocatorACE_Allocator associated with string
releaseAllocator responsible(true)/not responsible(false) for freeing memory.
Returns:
ACE_String_Base containing const ACE_CHAR_T *s
template<class ACE_CHAR_T>
ACE_String_Base< ACE_CHAR_T >::ACE_String_Base ( const ACE_String_Base< ACE_CHAR_T > &  s)

Copy constructor.

Parameters:
sInput ACE_String_Base string to copy
Returns:
Copy of input string s
template<class ACE_CHAR_T>
ACE_String_Base< ACE_CHAR_T >::ACE_String_Base ( ACE_CHAR_T  c,
ACE_Allocator the_allocator = 0 
)

Constructor that copies c into dynamically allocated memory.

ACE_String_Base< ACE_CHAR_T >::ACE_String_Base ( size_type  len,
ACE_CHAR_T  c = 0,
ACE_Allocator the_allocator = 0 
)

Constructor that allocates a len long string.

Warning : This constructor was incorrectly documented in the past. It simply calls resize(len, c). It is probably not advisable to use the second parameter. See resize() for more information.

Parameters:
lenAmount of space to reserve for the string.
cThe array is filled with c's
the_allocatorACE_Allocator associated with string
Returns:
Empty ACE_String_Base with room for len CHARs
template<class ACE_CHAR_T >
ACE_String_Base< ACE_CHAR_T >::~ACE_String_Base ( void  )

template<class ACE_CHAR_T>
ACE_String_Base< ACE_CHAR_T > & ACE_String_Base< ACE_CHAR_T >::assign_nocopy ( const ACE_String_Base< ACE_CHAR_T > &  s) [inline]

Assignment alternative method (does not copy memory).

Parameters:
sInput ACE_String_Base string to assign to this object.
Returns:
Return this string.
template<class ACE_CHAR_T >
ACE_String_Base< ACE_CHAR_T >::iterator ACE_String_Base< ACE_CHAR_T >::begin ( void  ) [inline]
template<class ACE_CHAR_T >
ACE_String_Base< ACE_CHAR_T >::const_iterator ACE_String_Base< ACE_CHAR_T >::begin ( void  ) const [inline]
template<class ACE_CHAR_T >
const ACE_CHAR_T * ACE_String_Base< ACE_CHAR_T >::c_str ( void  ) const [inline]

Same as STL String's c_str() and fast_rep().

template<class ACE_CHAR_T >
size_t ACE_String_Base< ACE_CHAR_T >::capacity ( void  ) const [inline]

Return the number of allocated CHARs in the string object. This may be greater than the current length of the string.

Returns:
Maximum number of ACE_CHAR_T units that can be stored, including any terminating nul that may be needed.
template<class ACE_CHAR_T >
void ACE_String_Base< ACE_CHAR_T >::clear ( bool  release = false)

Clear this string. Memory is _not_ freed if release is false.

Warning: This method was incorrectly documented in the past, but the current implementation has been changed to match the documented behavior.

Warning: clear(false) behaves like fast_clear() below.

Parameters:
releaseMemory is freed if true, and not freed if false.
template<class ACE_CHAR_T>
int ACE_String_Base< ACE_CHAR_T >::compare ( const ACE_String_Base< ACE_CHAR_T > &  s) const

Performs a strncmp comparison.

Parameters:
sInput ACE_String_Base string to compare against stored string.
Returns:
Integer value of result (less than 0, 0, greater than 0) depending on how input string s is to the stored string.
template<class ACE_CHAR_T >
void ACE_String_Base< ACE_CHAR_T >::dump ( void  ) const [inline]

Dump the state of an object.

template<class ACE_CHAR_T >
bool ACE_String_Base< ACE_CHAR_T >::empty ( void  ) const [inline]

Return true if the length of the string is zero, else false. We recommend using is_empty() instead since it's more consistent with the ACE container naming conventions.

template<class ACE_CHAR_T >
ACE_String_Base< ACE_CHAR_T >::iterator ACE_String_Base< ACE_CHAR_T >::end ( void  ) [inline]
template<class ACE_CHAR_T >
ACE_String_Base< ACE_CHAR_T >::const_iterator ACE_String_Base< ACE_CHAR_T >::end ( void  ) const [inline]
template<class ACE_CHAR_T >
void ACE_String_Base< ACE_CHAR_T >::fast_clear ( void  )

A more specialized version of clear(): "fast clear". fast_clear() resets the string to 0 length. If the string owns the buffer (

  • release_== true):
    • the string buffer is not freed
    • the first character of the buffer is set to 0.

If

  • release_ is false (this object does not own the buffer):
    • the buffer pointer is reset to the NULL_String_ and does not maintain a pointer to the caller-supplied buffer on return
    • the maximum string length is reset to 0.

Warning : Calling clear(false) or fast_clear() can have unintended side-effects if the string was constructed (or set()) with an external buffer. The string will be disassociated with the buffer and the next append() or +=() will cause a new buffer to be allocated internally.

template<class ACE_CHAR_T>
void ACE_String_Base< ACE_CHAR_T >::resize ( size_type  len,
ACE_CHAR_T  c = 0 
)

This method is designed for high-performance. Please use with care ;-)

Warning : This method was documented incorrectly in the past. The original intention was to change the length of the string to len, and to fill the whole thing with c CHARs. However, what was actually done was to set the length of the string to zero, and fill the buffer with c's. The buffer was also not null-terminated unless c happened to be zero. Rather than fix the method to work as documented, the code is left as is, but the second parameter should probably not be used.

fast_resize just adjusts the buffer if needed and sets the length, it doesn't fill the buffer, so is much faster.

Parameters:
lenThe number of CHARs to reserve
cThe ACE_CHAR_T to use when filling the string.
template<class ACE_CHAR_T>
size_type ACE_String_Base< ACE_CHAR_T >::rfind ( ACE_CHAR_T  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.

Parameters:
cInput character to search for in stored string.
posStarting index position to start searching for string str.
Returns:
Index value of the first location of string str else npos.
template<class ACE_CHAR_T>
void ACE_String_Base< ACE_CHAR_T >::set ( const ACE_CHAR_T *  s,
bool  release = true 
)

Copy s into this ACE_String_Base.

If release == true then a new buffer is allocated internally if the existing one is not big enough to hold s. If the existing buffer is big enough, then it will be used. This means that set(*, 1) can be illegal when the string is constructed with a const char*. (e.g. ACE_String_Base("test", 0, false)).

if release == false then the s buffer is used directly, and any existing buffer is destroyed. If s == 0 then it will _not_ be used, and instead the internal buffer is set to NULL_String_.

Parameters:
sNull terminated input string
releaseAllocator responsible(true)/not responsible(false) for freeing memory.
template<class ACE_CHAR_T>
void ACE_String_Base< ACE_CHAR_T >::set ( const ACE_CHAR_T *  s,
size_type  len,
bool  release 
)

Copy len bytes of s (will zero terminate the result).

If release == true then a new buffer is allocated internally if the existing one is not big enough to hold s. If the existing buffer is big enough, then it will be used. This means that set(*, *, 1) is illegal when the string is constructed with a non-owned const char*. (e.g. ACE_String_Base("test", 0, 0))

If release == false then the s buffer is used directly, and any existing buffer is destroyed. If s == 0 then it will _not_ be used, and instead the internal buffer is set to NULL_String_.

Parameters:
sNon-zero terminated input string
lenLength of input string 's'
releaseAllocator responsible(true)/not responsible(false) for freeing memory.
template<class ACE_CHAR_T>
ACE_String_Base< ACE_CHAR_T >::size_type ACE_String_Base< ACE_CHAR_T >::strstr ( const ACE_String_Base< ACE_CHAR_T > &  s) const [inline]

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

Parameters:
sInput ACE_String_Base string
Returns:
Integer index value of the first location of string s or npos (not found).
template<class ACE_CHAR_T>
ACE_String_Base< ACE_CHAR_T > ACE_String_Base< ACE_CHAR_T >::substr ( size_type  offset,
size_type  length = npos 
) const

Same as <substring>.

Returns:
The string containing the desired substring
template<class ACE_CHAR_T>
ACE_String_Base< ACE_CHAR_T > ACE_String_Base< ACE_CHAR_T >::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.

Parameters:
offsetIndex of first desired character of the substring.
lengthHow many characters to return starting at the offset.
Returns:
The string containing the desired substring
template<class ACE_CHAR_T>
void ACE_String_Base< ACE_CHAR_T >::swap ( ACE_String_Base< ACE_CHAR_T > &  str)
