Constructor Details

StaticPageStore

public StaticPageStore(@NotNull
 ColumnRegionObject<DATA_TYPE,ATTR>[] regions,
 @NotNull
 ParquetFormatColumnLocation<ATTR> location)

Method Details

getObject

public DATA_TYPE getObject(long elementIndex)

Description copied from interface: ColumnRegionObject

Get a single object from this region.

Specified by:

getObject in interface ColumnRegionObject<DATA_TYPE,ATTR extends Attributes.Values>

Parameters:

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

Returns:

The object value at the specified element (object) index

getObject

public DATA_TYPE 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<DATA_TYPE,ATTR extends Attributes.Values>

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

supportsDictionaryFormat

public RegionVisitResult supportsDictionaryFormat(@NotNull
 ReadOnlyIndex.SearchIterator keysToVisit)

Description copied from interface: ColumnRegionObject

Check if this region can expose an alternate form as paired regions of long keys and DATA_TYPE values covering all of its row keys in keysToVisit.

Both alternate regions must use the same or smaller row key space as this one. Indices fetched from the keys region must represent valid element indices in the values region. Values regions must support ColumnRegionObject.gatherDictionaryValuesRowSet(Index.SearchIterator, Index.Iterator, Index.SequentialBuilder).

Use ColumnRegionObject.getDictionaryKeysRegion() to access the region of keys and ColumnRegionObject.getDictionaryValuesRegion() to access the region of values.

Specified by:

supportsDictionaryFormat in interface ColumnRegionObject<DATA_TYPE,ATTR extends Attributes.Values>

Parameters:

keysToVisit - Iterator positioned at the first relevant row key belonging to this region. Will be advanced to after this region if true is returned. No guarantee is made if false is returned.

Returns:

A RegionVisitResult specifying FAILED if this region cannot supply a dictionary, CONTINUE if it can and keysToVisit is not exhausted, and COMPLETE if it can and keysToVisit is exhausted

gatherDictionaryValuesRowSet

public boolean gatherDictionaryValuesRowSet(@NotNull
 ReadOnlyIndex.SearchIterator keysToVisit,
 @NotNull
 ReadOnlyIndex.Iterator knownKeys,
 @NotNull
 Index.SequentialBuilder sequentialBuilder)

Description copied from interface: ColumnRegionObject

Optional method that should only be used on regions returned by ColumnRegionObject.getDictionaryValuesRegion(). Gathers

Specified by:

gatherDictionaryValuesRowSet in interface ColumnRegionObject<DATA_TYPE,ATTR extends Attributes.Values>

Parameters:

keysToVisit - A search iterator over the enclosing table address space (which must have the same regions at the same masks), positioned at a row key in this region. Used to identify regions to visit. Should be advanced to after this region as a side-effect.

knownKeys - An iterator over the previously-known row keys, positioned at the first known key in this region, or after the region's maximum key if no keys are known. Should be advanced to after this region as a side effect.

sequentialBuilder - Output builder; implementations should append ranges for row keys not found in knownKeys

Returns:

Whether keysToVisit has been exhausted

getDictionaryRegionType

public ChunkType getDictionaryRegionType()

Specified by:

getDictionaryRegionType in interface ColumnRegionObject<DATA_TYPE,ATTR extends Attributes.Values>

getDictionaryKeysRegion

public ColumnRegionLong<Attributes.DictionaryKeys> getDictionaryKeysRegion()

Description copied from interface: ColumnRegionObject

Get a view of this region as long dictionary keys.

Specified by:

getDictionaryKeysRegion in interface ColumnRegionObject<DATA_TYPE,ATTR extends Attributes.Values>

Returns:

A dictionary keys region as specified by ColumnRegionObject.supportsDictionaryFormat(Index.SearchIterator)

getDictionaryValuesRegion

public ColumnRegionObject<DATA_TYPE,ATTR> getDictionaryValuesRegion()

Description copied from interface: ColumnRegionObject

Get a view of this region as dictionary values.

Specified by:

getDictionaryValuesRegion in interface ColumnRegionObject<DATA_TYPE,ATTR extends Attributes.Values>

Returns:

A dictionary values region as specified by ColumnRegionObject.supportsDictionaryFormat(Index.SearchIterator)

getNativeType

public Class<?> getNativeType()

Specified by:

getNativeType in interface ChunkSource<DATA_TYPE>

Specified by:

getNativeType in interface ColumnRegionObject<DATA_TYPE,ATTR extends Attributes.Values>
