Detailed Description
Indexes packets in a file.
Member Function Documentation
| int MAKLogger::DtLgrPacketIndexer::addEntry | ( | double | time, |
| DtFilePosition | position, | ||
| int | size | ||
| ) |
Adds a index for a position, time and size.
- Returns:
- the index of the entry.
| void MAKLogger::DtLgrPacketIndexer::decodePacket | ( | const DtPacket * | packet | ) |
Decode index packet.
The existing entries will be cleared and replaced with the entries stored in the packet. throw DtInvalidInput if the packet is not an index table packet.
| int MAKLogger::DtLgrPacketIndexer::firstIndex | ( | ) |
Get the first index or -1 if no indices.
- Return values:
-
-1 no indices.
| int MAKLogger::DtLgrPacketIndexer::getIndexAtOrAfterTime | ( | double | time | ) |
Gets the first position after the time.
throw DtInvalidInput if the time is after the last time.
| int MAKLogger::DtLgrPacketIndexer::getIndexAtOrBeforeTime | ( | double | time | ) |
Gets the first position before time.
throw DtInvalidInput if the time is before the first time.
| DtFilePosition MAKLogger::DtLgrPacketIndexer::getPositionOfIndex | ( | int | index | ) |
Gets the position at the index.
throw DtInvalidInput if the index is invalid.
| int MAKLogger::DtLgrPacketIndexer::getSizeOfIndex | ( | int | index | ) |
Gets the size of the entry at the index.
throw DtInvalidInput if the index is invalid.
| double MAKLogger::DtLgrPacketIndexer::getTimeOfIndex | ( | int | index | ) |
Gets the time of the index.
throw DtInvalidInput if the index is invalid.
| int MAKLogger::DtLgrPacketIndexer::lastIndex | ( | ) |
Get the last index or -1 if no indices.
- Return values:
-
-1 no indices.
| void MAKLogger::DtLgrPacketIndexer::removeEntry | ( | int | index | ) |
Remove an entry.
- Warning:
- All indexes previously returned may be invalid after this call.
