Example 96 with Execution

use of org.apache.geode.cache.execute.Execution in project geode by apache.

the class PeerToPeerSessionCache method touchSessions.

@Override

    // Get the region attributes id to determine the region type. This is
    // problematic since the region attributes id doesn't really define the
    // region type. This should look at the actual session region.
    String regionAttributesID = getSessionManager().getRegionAttributesId().toLowerCase();
    // Invoke the appropriate function depending on the type of region
    ResultCollector collector = null;
    if (regionAttributesID.startsWith("partition")) {
        // Execute the partitioned touch function on the primary server(s)
        Execution execution = FunctionService.onRegion(getSessionRegion()).withFilter(sessionIds);
