Detailed Description

The abstraction of an interned string.

It's a wrapper around a pointer to a std::string, along with a set of method that helps make this string integrate with std::string seamlessly. For instance, the type provides equality operators that help compare it against std::string.

Note that this interned_string type is design to have the same size as a pointer to a string.

Constructor & Destructor Documentation

interned_string() [1/2]

interned_string ( )

inline

Default constructor.

Constructs an empty pointer to string.

Definition at line 59 of file abg-interned-str.h.

interned_string() [2/2]

interned_string ( const interned_string &  o )

inline

Copy constructor.

Parameters

o	the other instance to copy from.

Definition at line 66 of file abg-interned-str.h.

Member Function Documentation

clear()

void clear ( )

inline

Clear the string.

Definition at line 81 of file abg-interned-str.h.

empty()

bool empty ( ) const

inline

Test if the current instance of interned_string is empty.

Returns

true iff the currentisntance of interned_string is empty.

Definition at line 89 of file abg-interned-str.h.

operator string()

operator string ( ) const

inline

Conversion operator to string.

Returns

the underlying string this instance refers too.

Definition at line 174 of file abg-interned-str.h.

operator!=() [1/2]

bool operator!= ( const interned_string &  o ) const

inline

Inequality operator.

Parameters

o	the other interned_string to compare the current instance against.

Returns

true iff the current instance is different from the o.

Definition at line 123 of file abg-interned-str.h.

operator!=() [2/2]

bool operator!= ( const string &  o ) const

inline

Inequality operator.

Takes the current instance of interned_string and an instance of std::string.

Parameters

o	the instance of std::string to compare the current instance of interned_string against.

Returns

true if the current instance of interned_string is different from o.

Definition at line 154 of file abg-interned-str.h.

operator<()

bool operator< ( const interned_string &  o ) const

inline

"Less than" operator.

Lexicographically compares the current instance of interned_string against another instance.

Parameters

o	the other instance of interned_string to compare against.

Returns

true iff the current instance of interned_string is lexicographycally less than the string o.

Definition at line 167 of file abg-interned-str.h.

operator=()

interned_string & operator= ( const interned_string &  o )

inline

Assignment operator.

Parameters

o	the other instance to assign to the current one.

Definition at line 73 of file abg-interned-str.h.

operator==() [1/2]

bool operator== ( const interned_string &  o ) const

inline

Compare the current instance of interned_string against another instance of interned_string.

Note that this comparison is done in O(1), because it compares the pointer values of the two underlying pointers to std::string held by each instances of interned_string.

Parameters

o	the other interned_string to compare against.

Returns

true iff the current instance equals o.

Definition at line 112 of file abg-interned-str.h.

operator==() [2/2]

bool operator== ( const string &  o ) const

inline

Compare the current instance of interned_string against an instance of std::string.

Note that this comparison is done in O(N), N being the size (in number of characters) of the strings being compared.

Parameters

o	the instance of std::string to compare against.

Returns

true iff the current instance equals o.

Definition at line 136 of file abg-interned-str.h.

raw()

const string * raw ( ) const

inline

Return the underlying pointer to std::string that this interned_string wraps.

Returns

a pointer to the underlying std::string, or 0 if this interned_string is empty.

Definition at line 98 of file abg-interned-str.h.
