Method Details

getObject

public T getObject(long elementIndex)

Description copied from interface: ColumnRegionObject

Get a single object from this region.

Specified by:

getObject in interface ColumnRegionObject<T,ATTR extends Attributes.Any>

Parameters:

elementIndex - Element (object) index in the table's address space

Returns:

The object value at the specified element (object) index

getNativeType

public Class<T> getNativeType()

Specified by:

getNativeType in interface ChunkSource<T>

Specified by:

getNativeType in interface ColumnRegionObject<T,ATTR extends Attributes.Any>

Returns:

null

ImplNote:

This is never called, so we just return null so this class can remain a singleton.
