All Implemented Interfaces:

ChannelManager, ChannelManagerStandard, Closeable, AutoCloseable

@Deprecated
public class RollingFileManager
extends RollingFileManagerBase<String,Void>

Deprecated.

This class maintains the file channels, with the appropriate roll interval for BinaryStoreWriters. Each call to getChannel() evaluates the current time, and might re-initialize the channel. This class adds a time suffix to the configured location and file prefix. For example, "/db/TempFiles/irisadmin/logs", "DbInternal.UpdatePerformanceLog.localhost.bin.2018-04-16." to specify the log directory and file prefix or "/db/TempFiles/irisadmin/logs/DbInternal.UpdatePerformanceLog.localhost.bin.2018-04-16." to specify the directory and prefix together.

Parameters:

log - the Logger

baseDirName - log files will be placed in this directory

filenamePrefix - log files will begin with this prefix and end with the time according to rollFormat

headerBuffer - this buffer will be written to all new files

rollFormat - the current time will be formatted according to this formatter

existingFilePolicy - determines how existing files will be treated

Method Details

makeFilename

protected String makeFilename(String value,
 Void ignored)

Deprecated.

Description copied from class: RollingFileWriterBase

Construct the complete filename using the changing part passed in.

Specified by:

makeFilename in class RollingFileWriterBase<String,Void>

Parameters:

value - the changing portion of the filename based on our expiration

ignored - the changing portion of the filename based on our caller

Returns:

the filename, possibly combining other data with the value

getChannel

public GatheringByteChannel getChannel()
                                throws IOException

Deprecated.

Description copied from interface: ChannelManagerStandard

For ChannelManager implementations that don't support dynamic column partition determination, the channel is based on pre-determined criteria. The channel may still change, but not dynamically based on data that the ChannelManager user determines.

Returns:

a non-null, open GatheringByteChannel

Throws:

IOException - if the call encounters an error
