Example 1 with ISMRConsumable

use of org.corfudb.protocols.logprotocol.ISMRConsumable in project CorfuDB by CorfuDB.

the class StreamViewSMRAdapter method dataAndCheckpointMapper.

private List<SMREntry> dataAndCheckpointMapper(ILogData logData) {
    if (logData.hasCheckpointMetadata()) {
        // This is a CHECKPOINT record.  Extract the SMREntries, if any.
        CheckpointEntry cp = (CheckpointEntry) logData.getPayload(runtime);
        if (cp.getSmrEntries() != null && cp.getSmrEntries().getUpdates().size() > 0) {

Example 2 with ISMRConsumable

use of org.corfudb.protocols.logprotocol.ISMRConsumable in project CorfuDB by CorfuDB.
