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.

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 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`
	)

Constructor that copies c into dynamically allocated memory.

ACE_SString::~ACE_SString ( void )

inline

Default destructor.

Member Function Documentation

const char * ACE_SString::c_str ( void ) const

inline

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

int ACE_SString::compare ( const ACE_SString & s ) const

inline

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

inline

Get the underlying pointer.

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

inline

Find str 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

inline

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	(	char	c,
		size_type	pos = `0`
	)		const

inline

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

u_long ACE_SString::hash ( void ) const

inline

Returns a hash value for this string.

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

inline

Return the length of the string.

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

inline

Inequality comparison operator.

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

inline

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

inline

Equality comparison operator (must match entire string).

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

inline

Greater than comparison operator.

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

inline

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

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

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!!!

const char * ACE_SString::rep ( void ) const

inline

Get the underlying pointer.

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

inline

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

inline

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

inline

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
