Interface | Description |
---|---|
Loggable |
A class that implements Loggable knows how to read and write itself into
a ByteBuffer in a format suitable for the JE log or JE replication messages.
|
LogSource |
A class that implements LogSource can return portions of the log.
|
Class | Description |
---|---|
CheckpointFileReader |
CheckpointFileReader searches for root and checkpoint entries.
|
ChecksumValidator |
Checksum validator is used to check checksums on log entries.
|
CleanerFileReader |
CleanerFileReader scans log files for INs and LNs.
|
DbOpReplicationContext |
This subclass of ReplicationContext adds information specific to database
operations to the replication context passed from operation-aware code down
the the logging layer.
|
DumpFileReader |
The DumpFileReader prints every log entry to stdout.
|
FileHandle |
A FileHandle embodies a File and its accompanying latch.
|
FileHandleSource |
FileHandleSource is a file source built on top of a cached file handle.
|
FileHeader |
A FileHeader embodies the header information at the beginning of each log
file.
|
FileManager |
The FileManager presents the abstraction of one contiguous file.
|
FileReader |
A FileReader is an abstract class that traverses the log files, reading in
chunks of the file at a time.
|
FileReader.ReadWindow |
A ReadWindow provides a swathe of data read from the JE log.
|
FileSource |
FileSource is used as a channel to a log file when faulting in objects
from the log.
|
FSyncManager | |
FSyncManager.FSyncGroup | |
INFileReader |
INFileReader supports recovery by scanning log files during the IN rebuild
pass.
|
JEFileFilter |
JEFileFilters are used for listing je files.
|
LastFileReader |
LastFileReader traverses the last log file, doing checksums and looking for
the end of the log.
|
LNFileReader |
LNFileReader scans log files for LNs.
|
LogBuffer |
LogBuffers hold outgoing, newly written log entries.
|
LogBufferPool |
LogBufferPool keeps a set of log buffers.
|
LogContext |
Context parameters that apply to all logged items when multiple items are
logged in one log operation.
|
LogEntryHeader |
A LogEntryHeader embodies the header information at the beginning of each
log entry file.
|
LogEntryType |
LogEntryType is an enumeration of all log entry types.
|
LogItem |
Item parameters that apply to a single logged item.
|
LogManager |
The LogManager supports reading and writing to the JE log.
|
LogStatDefinition |
Per-stat Metadata for JE FileManager, FSyncManager, LogManager and
LogBufferPool statistics.
|
LogUtils |
This class holds convenience methods for marshalling internal JE data to and
from the log.
|
LogUtils.XidImpl | |
PrintFileReader |
The PrintFileReader prints out the target log entries.
|
ReplicationContext |
ReplicationContext provides context about high-level operations so that the
logging level can determine which replication related actions are required
for a given Loggable item.
|
ScavengerFileReader |
A ScavengerFileReader reads the log backwards.
|
SearchFileReader |
SearchFileReader searches for the a given entry type.
|
StatsFileReader |
The StatsFileReader generates stats about the log entries read, such as the
count of each type of entry, the number of bytes, minimum and maximum sized
log entry.
|
StatsFileReader.CheckpointCounter | |
StatsFileReader.EntryInfo | |
StatsFileReader.LogEntryTypeComparator | |
SyncedLogManager |
The SyncedLogManager uses the synchronized keyword to implement protected
regions.
|
Trace |
Trace logs event tracing messages into .jdb files.
|
UtilizationFileReader |
Summarizes the utilized and unutilized portion of each log file by examining
each log entry.
|
VLSNDistributionReader |
This is a debugging utility which implements the unadvertised DbPrintLog -vd
option, which displays VLSN distribution in a log.
|
WholeEntry |
This class packages the log entry header and the log entry "contents"
together for the use of components that need information from both parts.
|
Enum | Description |
---|---|
FileManager.FileMode | |
LogEntryType.Marshall | |
LogEntryType.NodeType | |
LogEntryType.Replicable | |
LogEntryType.Txnal | |
Provisional |
Specifies whether to log an entry provisionally.
|
Exception | Description |
---|---|
ChecksumException |
Indicates that a checksum validation failed.
|
FileReader.EOFException |
Never seen by user, used to indicate that the file reader should stop.
