Enum DbOperationType

java.lang.Object

java.lang.Enum<DbOperationType>

com.sleepycat.je.log.entry.DbOperationType

All Implemented Interfaces:

Loggable, java.io.Serializable, java.lang.Comparable<DbOperationType>

public enum DbOperationType
extends java.lang.Enum<DbOperationType>
implements Loggable

DbOperationType is a persistent enum used in NameLNLogEntries. It supports replication of database operations by documenting the type of api operation which instigated the logging of a NameLN.

Method Detail

values

public static DbOperationType[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (DbOperationType c : DbOperationType.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static DbOperationType valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

readTypeFromLog

public static DbOperationType readTypeFromLog(java.nio.ByteBuffer entryBuffer,
                              int entryVersion)

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,
               int entryVersion)

Description copied from interface: Loggable

Initialize this object from the data in itemBuf.

Specified by:

readFromLog in interface Loggable

See Also:

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

dumpLog

public void dumpLog(java.lang.StringBuilder 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.StringBuilder, 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.

See Also:

Loggable.logicalEquals(com.sleepycat.je.log.Loggable)

isWriteConfigType

public static boolean isWriteConfigType(DbOperationType opType)

Return true if this databaes operation type needs to write DatabaseConfig.
