Method Detail

writePosition

WireStore writePosition(long position)

epoch

long epoch()

Returns:

an epoch offset as the number of number of milliseconds since January 1, 1970, 00:00:00 GMT, if you set the epoch to the current time, then the cycle will be ZERO

writePosition

long writePosition()

Returns:

the next writable position, Will be or-ed with ROLLED_BIT if it has rolled.

lastEntryIndexed

long lastEntryIndexed(net.openhft.chronicle.wire.Wire wire,
                      long timeoutMS)

Returns:

the sequence number with the cycle
