Method Detail

epoch

long epoch()

storeForCycle

@Nullable
WireStore storeForCycle(int cycle,
                                  long epoch,
                                  boolean createIfAbsent)

Parameters:

cycle - the cycle

epoch - an epoch offset as the number of number of milliseconds since January 1, 1970, 00:00:00 GMT

createIfAbsent - create missing stores if true, or return null if missing

Returns:

the WireStore associated with this cycle, or null if !createIfAbsent is false and absent

release

Parameters:

store - the store to release

firstCycle

int firstCycle()

Returns:

the first cycle number found, or Integer.MAX_VALUE is none found.

lastCycle

int lastCycle()

Returns:

the lastCycle available or Integer.MIN_VALUE if none is found.

cycle

int cycle()

Returns:

the current cycle

rollCycle
