Interface ScopedPersistentState

All Known Implementing Classes:

public interface ScopedPersistentState
ScopedPersistentState represents state which needs to be persisted, scoped by name (e.g. the cache name). The default implementation of persistent state uses the standard Properties format with the additional rule that order is preserved. In order to verify state consistency (e.g. across a cluster) a checksum of the state's data can be computed. State properties prefixed with the '@' character will not be included as part of the checksum computation (e.g. @timestamp)
