Package com.illumon.iris.db.v2.sources.regioned

Class ColumnRegionObjectCodecFixed<T,ATTR extends Attributes.Any>

java.lang.Object

com.illumon.iris.db.v2.sources.regioned.ColumnRegionObjectCodecFixed<T,ATTR>

Type Parameters:

T - The realized type of the encoded objects within this region

ATTR - The Chunk attribute for this region

All Implemented Interfaces:

ChunkSource<ATTR>, DefaultChunkSource<ATTR>, FillContextMaker, GetContextMaker, Page<ATTR>, Page.WithDefaults<ATTR>, PagingChunkSource<ATTR>, ColumnRegion<ATTR>, ColumnRegionObject<T,ATTR>, Releasable

public final class ColumnRegionObjectCodecFixed<T,ATTR extends Attributes.Any>
extends Object
implements ColumnRegionObject<T,ATTR>, Page.WithDefaults<ATTR>

A ColumnRegion for non-primitive types that have a fixed size. The objects are stored in raw encoded binary format within a single data file.

ColumnRegionObjectCodecFixed

public ColumnRegionObjectCodecFixed(@NotNull Class<T> nativeType, @NotNull ObjectDecoder<T> decoder, @NotNull ColumnRegionByte<Attributes.EncodedObjects> binaryBytes)

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

getObject

public T getObject(@NotNull ChunkSource.FillContext context, 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:

context - A ColumnRegionFillContext to enable resource caching where suitable, with current region index pointing to this region

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

Returns:

The object value at the specified element (object) index

fillChunkAppend

public void fillChunkAppend(@NotNull ChunkSource.FillContext fillContext, @NotNull WritableChunk<? super ATTR> destination, @NotNull OrderedKeys orderedKeys)

Description copied from interface: Page.WithDefaults

Appends the values referenced by orderKeys onto destination. orderKeys are assumed to be entirely contained on this Page.

Specified by:

fillChunkAppend in interface Page.WithDefaults<T>

Specified by:

length in interface Page<T>

Returns:

the length of this page.

releaseCachedResources

@OverridingMethodsMustInvokeSuper public void releaseCachedResources()

Description copied from interface: Releasable
