sources

int sources()

Returns the number of sources contained in this MessageHistory.

Returns:

the number of sources contained in this MessageHistory.

sourceId

int sourceId(int n)

Returns the source id at a position specified by the input n.

Returns:

the source id at a position specified by the input n.

sourceIdsEndsWith

boolean sourceIdsEndsWith(int[] sourceIds)

Specified by:

reset in interface Marshallable

Specified by:

reset in interface net.openhft.chronicle.core.io.Resettable

reset

void reset(int sourceId,
           long sourceIndex)

Resets the MessageHistory with the provided sourceId and sourceIndex as a starting point.

lastSourceId
