Detailed Description

string type.

a string is contiguous sequence of 8-bit characters. The sequence is defined by a pair of pointers. The first pointer begin points to the first character; the second pointer end points to the first charcter past the end of the sequence. A string may contain any character. A string may also be empty (when begin == end.)

string_ts are immutable strings, in the sense that string_t does not provide methods to modify the value of a string_t.

Examples:

Constructor & Destructor Documentation

siena::string_t::string_t ( const string_t &  x )

inline

constructs a copy of a given string.

The copy is simply a copy of the reference. In other words, this method does not allocate memory for the string value. Instead, the new string will point to the same sequence of the given string.

Member Function Documentation

string_t& siena::string_t::assign ( const char *  b, const char *  e  )

inline

assigns this string to the given sequence.

This method does not allocate memory.

References begin, and end.

bool siena::string_t::operator< ( const string_t &  x ) const

inline

lexicographical order relation.

returns true iff this string lexicographically precedes the given string.

References begin, and end.

string_t& siena::string_t::operator= ( const string_t  x )

inline

assigns this string to the given string.

This method does not allocate memory. Instead, this string will point to the same memory sequence pointed by the given string.

References begin, and end.

bool siena::string_t::operator> ( const string_t &  x ) const

inline

lexicographical order relation.

returns true iff this string lexicographically follows the given string.
