IndexSegmentBuilder.AbstractSimpleNodeData(int level, int m)

Method Summary

AbstractFixedByteArrayBuffer	data() The coded (aka compressed) data.
int	getKeyCount()
IRaba	getKeys()
long	getMaximumVersionTimestamp() The most recent tuple revision timestamp associated with any tuple spanned by this node or leaf.
long	getMinimumVersionTimestamp() The earliest tuple revision timestamp associated with any tuple spanned by this node or leaf.
boolean	isCoded() No.
boolean	isReadOnly() Yes (however, note that the IndexSegmentBuilder directly accesses and modified the internal data structures).

                                                     int m)

Method Detail

reset

protected void reset(int max)

Parameters:

max - The #of children to be assigned to this node -or- the #of tuples to be assigned to a leaf.

getKeyCount

public final int getKeyCount()

getKeys

public final IRaba getKeys()

isReadOnly

public final boolean isReadOnly()

Yes (however, note that the IndexSegmentBuilder directly accesses and modified the internal data structures).

Specified by:

isReadOnly in interface IAbstractNodeData

isCoded

public final boolean isCoded()

No.

Specified by:

isCoded in interface IAbstractNodeData

data

public final AbstractFixedByteArrayBuffer data()

Description copied from interface: IAbstractNodeData

The coded (aka compressed) data.

Specified by:

data in interface IAbstractNodeData

Specified by:

data in interface IDataRecordAccess

getMaximumVersionTimestamp

public final long getMaximumVersionTimestamp()

Description copied from interface: IAbstractNodeData

The most recent tuple revision timestamp associated with any tuple spanned by this node or leaf. If there are NO tuples for the leaf, then this MUST return Long.MIN_VALUE since the initial value of the maximum version timestamp is always the smallest possible long integer.

Specified by:

getMaximumVersionTimestamp in interface IAbstractNodeData

getMinimumVersionTimestamp

public final long getMinimumVersionTimestamp()

Description copied from interface: IAbstractNodeData

The earliest tuple revision timestamp associated with any tuple spanned by this node or leaf. If there are NO tuples for the leaf, then this MUST return Long.MAX_VALUE since the initial value of the minimum version timestamp is always the largest possible long integer.

Specified by:

getMinimumVersionTimestamp in interface IAbstractNodeData
