Member Function Documentation
| virtual qdbm::Datum::operator const char * |
( |
|
) |
const [virtual] |
Cast operator into pointer to char.
- Returns:
- the pointer of the region of the datum.
- Note:
- Because an additional zero code is appended at the end of the region of the return value, the return value can be treated as a character string.
| virtual bool qdbm::Datum::operator!= |
( |
const char * |
str |
) |
const [virtual] |
Inequality operator.
- Parameters:
-
- Returns:
- true if both do not equal, else, false.
| virtual bool qdbm::Datum::operator!= |
( |
const Datum & |
datum |
) |
const [virtual] |
Inequality operator.
- Parameters:
-
| datum | a comparing instance. |
- Returns:
- true if both do not equal, else, false.
| virtual Datum& qdbm::Datum::operator<< |
( |
const char * |
str |
) |
[virtual] |
Concatenation operator.
- Parameters:
-
- Returns:
- reference to itself.
| virtual Datum& qdbm::Datum::operator<< |
( |
const Datum & |
datum |
) |
[virtual] |
Concatenation operator.
- Parameters:
-
- Returns:
- reference to itself.
| Datum& qdbm::Datum::operator= |
( |
const char * |
str |
) |
|
Assignment operator.
- Parameters:
-
- Returns:
- reference to itself.
| Datum& qdbm::Datum::operator= |
( |
const Datum & |
datum |
) |
|
Assignment operator.
- Parameters:
-
- Returns:
- reference to itself.
| virtual bool qdbm::Datum::operator== |
( |
const char * |
str |
) |
const [virtual] |
Equality operator.
- Parameters:
-
- Returns:
- true if both equal, else, false.
| virtual bool qdbm::Datum::operator== |
( |
const Datum & |
datum |
) |
const [virtual] |
Equality operator.
- Parameters:
-
| datum | a comparing instance. |
- Returns:
- true if both equal, else, false.
| virtual char& qdbm::Datum::operator[] |
( |
int |
idx |
) |
const [virtual] |
Subscripting operator.
- Parameters:
-
| idx | the index of a character. |
- Returns:
- reference of the character.
| virtual const char* qdbm::Datum::ptr |
( |
|
) |
const [virtual] |
Get the pointer of the region of the datum.
- Returns:
- the pointer of the region of the datum.
- Note:
- Because an additional zero code is appended at the end of the region of the return value, the return value can be treated as a character string.
| virtual int qdbm::Datum::size |
( |
|
) |
const [virtual] |
Get the size of the region of the datum.
- Returns:
