Method Detail

writePosition

@NotNull
WireStore writePosition(long position)

Parameters:

position - the start of the last written excerpt to this cycle/store

Returns:

this store

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

lastIndexReplicated

long lastIndexReplicated()

when using replication to another host, this is the last index that has been sent to the remote host.

lastIndexReplicated

void lastIndexReplicated(long lastIndex)

Parameters:

lastIndex - last index that has been sent to the remote host.

writePosition

long writePosition()

Returns:

the start of the last written excerpt to this cycle/store
