Constructor Detail

DBIN

public DBIN()

DBIN

public DBIN(SizeofMarker marker)

For Sizeof, set all array fields to null, since they are not part of the fixed overhead.

Method Detail

isDBIN

public boolean isDBIN()

Overrides:

isDBIN in class Node

containsDuplicates

public boolean containsDuplicates()

Description copied from class: Node

Since DIN/DBIN/DupCountLN are no longer used in the Btree, this method should normally only be used by dup conversion or entities that do not access records via the Btree.

Overrides:

containsDuplicates in class Node

Returns:

true if this node is a duplicate-bearing node type, false if otherwise.

getFixedMemoryOverhead

protected long getFixedMemoryOverhead()

Overrides:

getFixedMemoryOverhead in class BIN

beginTag

public String beginTag()

Overrides:

beginTag in class BIN

endTag

public String endTag()

Overrides:

endTag in class BIN

dumpString

public String dumpString(int nSpaces,
                         boolean dumpTags)

For unit test support:

Overrides:

dumpString in class IN

Returns:

a string that dumps information about this IN, without

getLogType

public LogEntryType getLogType()

Description copied from class: IN

Get the log type of this node.

Overrides:

getLogType in class BIN

See Also:

IN.getLogType()

getLogSize

public int getLogSize()

Specified by:

getLogSize in interface Loggable

Overrides:

getLogSize in class IN

Returns:

number of bytes used to store this object.

See Also:

Loggable.getLogSize()

writeToLog

public void writeToLog(ByteBuffer logBuffer)

Description copied from interface: Loggable

Serialize this object into the buffer.

Specified by:

writeToLog in interface Loggable

Overrides:

writeToLog in class IN

Parameters:

logBuffer - is the destination buffer

See Also:

Loggable.writeToLog(java.nio.ByteBuffer)

readFromLog

public void readFromLog(ByteBuffer itemBuffer,
                        int entryVersion)

Description copied from interface: Loggable

Initialize this object from the data in itemBuf.

Specified by:

readFromLog in interface Loggable

Overrides:

readFromLog in class IN

Parameters:

itemBuffer - the source buffer

entryVersion - the log version of the data

See Also:

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

dumpLogAdditional

protected void dumpLogAdditional(StringBuilder sb)

DBINS need to dump their dup key

Overrides:

dumpLogAdditional in class IN

shortClassName

public String shortClassName()

Overrides:

shortClassName in class BIN
