Method Details

getObject

public STRING_LIKE_TYPE getObject(long elementIndex)

Description copied from interface: ColumnRegionObject

Get a single object from this region.

Specified by:

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

Parameters:

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

Returns:

The object value at the specified element (object) index

length

public long length()

Specified by:

length in interface Page<ATTR extends Attributes.Any>

Returns:

the length of this page.

getNativeType

public Class<?> getNativeType()

Specified by:

getNativeType in interface ChunkSource<ATTR extends Attributes.Any>

Specified by:

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

getChunk

public Chunk<? extends ATTR> getChunk(@NotNull ChunkSource.GetContext context, long firstKey, long lastKey)

Description copied from interface: ChunkSource

Same as ChunkSource.getChunk(GetContext, OrderedKeys), except that you pass in the begin and last keys representing the begin and last (inclusive) keys of a single range rather than an OrderedKeys. Typically you want to call this only if you don't have an OrderedKeys, such as during an OrderedKeys.forAllLongRanges(LongRangeConsumer) call. In this case, it allows you to avoid creating an intermediary OrderedKeys object.

Specified by:

getChunk in interface ChunkSource<ATTR extends Attributes.Any>

Specified by:

getChunk in interface DefaultChunkSource<ATTR extends Attributes.Any>

Specified by:

getChunk in interface DefaultChunkSource.SupportsContiguousGet<ATTR extends Attributes.Any>

Parameters:

context - A context containing all mutable/state related data used in retrieving the Chunk. In particular, the Context may be used to provide a Chunk data pool

firstKey - The beginning key (inclusive) of the range to fetch in the chunk

lastKey - The last key (inclusive) of the range to fetch in the chunk

Returns:

A chunk of data corresponding to the keys from the given range.

fillChunkAppend

public void fillChunkAppend(@NotNull ChunkSource.FillContext context, @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<ATTR extends Attributes.Any>
