Class Summary

Class	Description
AbstractJournalRM	The AbstractJournalRM represents a Journal Resource Manager that manages storage for journaled data, and acts as a shared resource for any number of journals that share a common configuration.
AbstractJournalRM.DefaultDependencies	The DefaultDependencies class provides a default implementation of Dependencies.
BackupJournalRM	The BackupJournalRM is a "meta" journal resource manager that is intended to be used for storage of "backup" data.
FlashJournalRM	A FlashJournalRM manages disk I/O for temporary journal-based files, and acts as a shared resource for any number of journals that share a common configuration.
FlashJournalRM.Buffer	A Buffer is a handy shell with some helper methods around a byte[] and a ByteBuffer.
FlashJournalRM.BufferPool	The BufferPool class recycles up to a maximum number of Buffer objects.
FlashJournalRM.CongestionPolicy	A CongestionPolicy defines how to behave when the currently active FlashJournalRM.JournalFile becomes congested.
FlashJournalRM.DefaultDependencies	The DefaultDependencies class provides a default implementation of Dependencies.
FlashJournalRM.FailCongestionPolicy	A FlashJournalRM.CongestionPolicy that fails, by throwing an unchecked exception, when FlashJournalRM.FailCongestionPolicy.onCongestion(com.tangosol.io.journal.FlashJournalRM.JournalFile) is invoked.
FlashJournalRM.WaitCongestionPolicy	A FlashJournalRM.CongestionPolicy which blocks the current thread on the FlashJournalRM.JournalFile's monitor until awoken.
JournalBinaryStore	A BinaryStore that writes to a Journal.
JournalBinaryStore.ClearListener	The ClearListener is used to ensure that entries are removed from the journal when the corresponding keys are cleared from the ticket tree.
JournalService	A JournalService manages the lifecycle for the RamJournalRM, FlashJournalRM, and the BackupJournalRM.
RamJournalRM	A RamJournalRM manages memory buffers for journal-based storage in memory, and acts as a shared resource for any number of journals that share a common configuration.
RamJournalRM.DefaultDependencies	The DefaultDependencies class provides a default implementation of Dependencies.
