Enabled/disable cache coherence mode for this node.

isClusterCoherent

boolean isClusterCoherent()

Is the cache coherent cluster-wide?

isNodeCoherent

boolean isNodeCoherent()

Is the cache coherent locally?

setEnabled

void setEnabled(boolean enabled)

Enabled/disable the cache.

removeAll

void removeAll()

Removes all cached items.

flush

void flush()

clearStatistics

void clearStatistics()

Clear both sampled and cumulative statistics

Specified by:

clearStatistics in interface LiveCacheStatistics

Specified by:

clearStatistics in interface SampledCacheStatistics

enableStatistics

void enableStatistics()

Enables statistics collection

disableStatistics

void disableStatistics()
