Public Member Functions | |
| Value (IValue *value=0) | |
| bool | operator! () const |
| Returns true, if this class is not connected to a actual statement. | |
| const IValue * | getImpl () const |
| Returns the actual implementation-class. | |
| bool isNull | ( | ) | const |
Explicit data-access. The get-methods return the value in the requested type. If the value can't be converted to the requested type, a exception of type tntdb::TypeError is thrown.
Referenced by Row::isNull().
| void getString | ( | std::string & | ret | ) | const |
fills the passed string with the value. this might be slightly more efficient than just returning a new string since one copy is saved.
| Blob getBlob | ( | ) | const |
Returns the value as a blob. This is more or less an alias to getString just to stress, that the data is truly binary and not some text value.
| operator bool | ( | ) | const |
Make Value-objects implicit convertable. This class defines implicit convert-operators to convert the value automatically to different types. They are identical with the corresponding get-methods.
