com.sleepycat.je.dbi.ReplicatedDatabaseConfig

All Implemented Interfaces:

Loggable

public class ReplicatedDatabaseConfig
extends java.lang.Object
implements Loggable

This class contains all fields of the database configuration which are persistent. This class is logged as part of a nameLN so that databases can be created on replica nodes with the correct configuration.

Method Detail

getReplicaConfig

public DatabaseConfig getReplicaConfig()
                                throws java.lang.ClassNotFoundException,
                                       LogException

Create a database config for use on the replica which contains all the configuration options that were conveyed by way of this class.

Throws:

java.lang.ClassNotFoundException

LogException

getLogSize

public int getLogSize()

Specified by:

getLogSize in interface Loggable

Returns:

number of bytes used to store this object.

See Also:

Loggable.getLogSize()

writeToLog

public void writeToLog(java.nio.ByteBuffer logBuffer)

Description copied from interface: Loggable

Serialize this object into the buffer.

Specified by:

writeToLog in interface Loggable

Parameters:

logBuffer - is the destination buffer

See Also:

Loggable.writeToLog(java.nio.ByteBuffer)

readFromLog

public void readFromLog(java.nio.ByteBuffer itemBuffer,
               byte entryVersion)
                 throws LogException

Description copied from interface: Loggable

Initialize this object from the data in itemBuf.

Specified by:

readFromLog in interface Loggable

Throws:

LogException

See Also:

Loggable.readFromLog(java.nio.ByteBuffer, byte)

dumpLog

public void dumpLog(java.lang.StringBuffer sb,
           boolean verbose)

Description copied from interface: Loggable

Write the object into the string buffer for log dumping. Each object should be dumped without indentation or new lines and should be valid XML.

Specified by:

dumpLog in interface Loggable

Parameters:

sb - destination string buffer

verbose - if true, dump the full, verbose version

See Also:

Loggable.dumpLog(java.lang.StringBuffer, boolean)

getTransactionId

public long getTransactionId()

Specified by:

getTransactionId in interface Loggable

Returns:

the transaction id embedded within this loggable object. Objects that have no transaction id should return 0.

See Also:

Loggable.getTransactionId()

logicalEquals

public boolean logicalEquals(Loggable other)

Specified by:

logicalEquals in interface Loggable

Returns:

true if these two loggable items are logically the same. Used for replication testing.
