Create an iterator given a pointer to a null terminated string.
The iterator will return characters from the start of the string when next called. The string is not copied into the iterator, so it must remain valid while the iteration is in progress.
| p | A pointer to the start of the null terminated string to read. |

| Xapian::Utf8Iterator::Utf8Iterator | ( | const char * | p_, | |

| ) | [inline] |
Create an iterator given a pointer and a length.
The iterator will return characters from the start of the string when next called. The string is not copied into the iterator, so it must remain valid while the iteration is in progress.
| p | A pointer to the start of the string to read. | |
| len | The length of the string to read. |
| Xapian::Utf8Iterator::Utf8Iterator | ( | const std::string & | s | ) | [inline] |
Create an iterator given a string.
The iterator will return characters from the start of the string when next called. The string is not copied into the iterator, so it must remain valid while the iteration is in progress.
| s | The string to read. Must not be modified while the iteration is in progress. |

Assign a new string to the iterator.
The iterator will forget the string it was iterating through, and return characters from the start of the new string when next called. The string is not copied into the iterator, so it must remain valid while the iteration is in progress.
| p | A pointer to the start of the string to read. | |
| len | The length of the string to read. |

| unsigned Xapian::Utf8Iterator::operator * | ( | ) | const |
Get the current unicode character value pointed to by the iterator.
Returns unsigned(-1) if the iterator has reached the end of its buffer.
