Constructor Detail

ARRSCellDataSource

public ARRSCellDataSource()

Construct a ARRSCellDataSource without arguments

ARRSCellDataSource

public ARRSCellDataSource(ARRSTree tree,
                  DataSource pointds)

Construct a ARRSCellDataSource with an ARRSTree

Method Detail

activate

public void activate()

Construct a ARRSCellDataSource with the given base bounds and number of attributes ***************** rdb delete **************** public ARRSCellDataSource( ISBounds basebounds, RecordDescriptor recordDesc ) { super( basebounds, recordDesc ); this.pointDS = null; this.tree = null; this.subtree = null; }

Overrides:

activate in class DataSource

deactivate

public void deactivate()

Description copied from class: DataSource

The DataSource will release any resources used during the readling or processing of data. It is important that all child classes call super.deactivate()

Overrides:

deactivate in class DataSource

setBaseBounds

public void setBaseBounds(ISBounds basebounds)

Set the base bounds

setPointDS

public void setPointDS(DataSource pds)

Set the point datasource

setARRSTree

public void setARRSTree(ARRSTree tree)

Set an ARRS tree

init

protected void init()

getARRSTree

public ARRSTree getARRSTree()

Get an ARRS tree

getPointDS

public DataSource getPointDS()

Get the point datasource

volume

public int volume()

Size of the ARRSCellDataSource -- not implemented

Overrides:

volume in class DataCollection

size

public int size()

Deprecated. Use volume instead

Description copied from class: DataCollection

Return the number of datums .

Overrides:

size in class DataCollection

Returns:

getBaseBounds

public ISBounds getBaseBounds()

Get the base bounds

setDatum

public void setDatum(IndexSpaceID isid,
            Datum d)

Set the location specified by the IndexSpaceID to the given datum.

subblock

public abstract DataBlock subblock(ISBounds db)
