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::clearEntries

(

)

Remove all entries.

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.

DtPacket* MAKLogger::DtLgrPacketIndexer::encodePacket

(

)

const

Encode index into 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::indexCount

(

)

const

Gets the number of indices currently in the indexer.

int MAKLogger::DtLgrPacketIndexer::lastIndex

(

)

Get the last index or -1 if no indices.

Return values

-1	no indices.

DtLgrPacketIndexer& MAKLogger::DtLgrPacketIndexer::operator= ( const DtLgrPacketIndexer &  )

private

Not Implemented.

void MAKLogger::DtLgrPacketIndexer::removeEntry

(

int

index

)

Remove an entry.

Warning

All indexes previously returned may be invalid after this call.
